Stress physiology and inflammation

وَنُوحًا إِذۡ نَادَىٰ مِن قَبۡلُ فَٱسۡتَجَبۡنَا لَهُۥ فَنَجَّيۡنَٰهُ وَأَهۡلَهُۥ مِنَ ٱلۡكَرۡبِ ٱلۡعَظِيمِ

Long before that, We answered Noah when he cried out to Us: We saved him and his family from the great calamity

وَنَجَّيۡنَٰهُمَا وَقَوۡمَهُمَا مِنَ ٱلۡكَرۡبِ ٱلۡعَظِيمِ

We saved them and their people from great distress

وَنَجَّيۡنَٰهُ وَأَهۡلَهُۥ مِنَ ٱلۡكَرۡبِ ٱلۡعَظِيمِ

We saved him and his people from great distress

قُلِ ٱللَّهُ يُنَجِّيكُم مِّنۡهَا وَمِن كُلِّ كَرۡبࣲ ثُمَّ أَنتُمۡ تُشۡرِكُونَ

Say, ‘God rescues you from this and every distress; yet still you worship others beside Him.’

وَلَمَّا بَلَغَ أَشُدَّهُۥٓ ءَاتَيۡنَٰهُ حُكۡمࣰ ا وَعِلۡمࣰ اۚ وَكَذَٰلِكَ نَجۡزِي ٱلۡمُحۡسِنِينَ

When he reached maturity, We gave him judgement and knowledge: this is how We reward those who do good

وَلَا تَقۡرَبُواْ مَالَ ٱلۡيَتِيمِ إِلَّا بِٱلَّتِي هِيَ أَحۡسَنُ حَتَّىٰ يَبۡلُغَ أَشُدَّهُۥۚ وَأَوۡفُواْ ٱلۡكَيۡلَ وَٱلۡمِيزَانَ بِٱلۡقِسۡطِۖ لَا نُكَلِّفُ نَفۡسًا إِلَّا وُسۡعَهَاۖ وَإِذَا قُلۡتُمۡ فَٱعۡدِلُواْ وَلَوۡ كَانَ ذَا قُرۡبَىٰۖ وَبِعَهۡدِ ٱللَّهِ أَوۡفُواْۚ ذَٰلِكُمۡ وَصَّىٰكُم بِهِۦ لَعَلَّكُمۡ تَذَكَّرُونَ

Stay well away from the property of orphans, except with the best [intentions], until they come of age; give full measure and weight, according to justice’- We do not burden any soul with more than it can bear- ‘ when you speak, be just, even if it concerns a relative; keep any promises you make in God’s name. This is what He commands you to do, so that you may take heed’

And mention Noah what follows Nūhan substitutes for it when he called when he supplicated to God against his people — with the words My Lord do not leave upon the earth any inhabitant from among the disbelievers … to the end of the verse Q. 7126 before that is before the time of Abraham and Lot. And We responded to him and delivered him and his people who were in the Ark with him from the great agony namely from drowning and his people’s denial of him.

and We delivered them and their people the Children of Israel from the great distress namely Pharaoh’s enslavement of them.

And We delivered him and his family from the great distress which was the drowning

And (remember) Nuh, when he cried (to Us) aforetime. We answered to his invocation and saved him and his family from the great distress (76)We helped him against the people who denied Our Ayat. Verily, they were a people given to evil. So We drowned them all (77) Nuh and His People Allah tells us how He responded to His servant and Messenger Nuh, peace be upon him, when he prayed to Him against his people for their disbelief in him: فَدَعَا رَبَّهُ أَنِّي مَغْلُوبٌ فَانتَصِرْ (Then he invoked his Lord (saying): "I have been overcome, so help (me)!")(54:10) وَقَالَ نُوحٌ رَّبِّ لَا تَذَرْ عَلَى الْأَرْضِ مِنَ الْكَافِرِينَ دَيَّارًا - إِنَّكَ إِن تَذَرْهُمْ يُضِلُّوا عِبَادَكَ وَلَا يَلِدُوا إِلَّا فَاجِرًا كَفَّارًا (And Nuh said: "My Lord! Leave not any inhabitant of the disbelievers on the earth! If You leave them, they will mislead Your servants, and they will beget none but wic

And, indeed We gave Our grace to Musa and Harun (114)And We saved them and their people from the great distress (115)And helped them, so that they became the victors (116)And We gave them the clear Scripture (117)And guided them to the right path (118)And We left for them among the later generations (119)"Salam (peace!) be upon Musa and Harun! (120)Verily, thus do We reward the doers of good (121)Verily, they were two of Our believing servants (122) Musa and Harun Allah tells us how He blessed Musa and Harun with prophethood and how He saved them, along with those who believed, from the oppression of Fir'awn and his people, who had persecuted them by killing their sons and sparing their women, and by forcing them to do the most menial tasks, then ultimately He caused them to prevail over them and to seize their lands and their wealth and all that they had spent their entire lives amass

And indeed Nuh invoked Us, and We are the best of those who answer (75)And We rescued him and his family from the great distress (76)And, his progeny, them We made the survivors (77)And left for him (a goodly remembrance) among the later generation (78)"Salam (peace!) be upon Nuh among the all creatures! (79)Verily, thus We reward the gooddoers (80)Verily, he [Nuh] was one of Our believing servants (81)Then We drowned the others (82) Nuh and His People When Allah tells us about how most of the early people went astray from the path of salvation, He starts the detailed explanation of that with the story of Nuh and the rejection of his people. Only a few of Nuh's people believed in him, despite the long period of time he spent among them. He stayed among them for one thousand years less fifty, and after he stayed among them for so long and their disbelief became too much for him to bear

Narrated Abu Huraira:Allah's Messenger (ﷺ) said, "The example of a believer is that of a fresh tender plant; from whatever direction the wind comes, it bends it, but when the wind becomes quiet, it becomes straight again. Similarly, a believer is afflicted with calamities (but he remains patient till Allah removes his difficulties.) And an impious wicked person is like a pine tree which keeps hard and straight till Allah cuts (breaks) it down when He wishes." (See Hadith No. 558, Vol)

Umm Al-Mundhir said:"The Messenger of Allah (ﷺ) entered upon me, while `Ali was with him, and we had a cluster of unripe dates hanging." She said: "The Messenger of Allah (ﷺ) began eating, and `Ali ate with him. The Messenger of Allah (ﷺ) said to `Ali: 'Stop, stop, for you are still recovering.' So `Ali sat and the Prophet (ﷺ) ate." She said: "I made some chard and barley for them, so the Prophet (ﷺ) said: 'O `Ali eat from this, for indeed it will be more suitable for you." Another chain reports a similar narration

Disruption of multisystem responses to stress in type 2 diabetes: investigating the dynamics of allostatic load.: Psychological stress-related processes are thought to contribute to the development and progression of type 2 diabetes, but the biological mechanisms involved are poorly understood. Here, we tested the notion that people with type 2 diabetes experience chronic allostatic load, manifest as dynamic disturbances in reactivity to and recovery from stress across multiple (cardiovascular, neuroendocrine, inflammatory, metabolic) biological systems, coupled with heightened experience of chronic life st

The influences of vitamin D and omega-3 co-supplementation on clinical, metabolic and genetic parameters in women with polycystic ovary syndrome.: Objective: The aim of this study was to evaluate the effect of the co-administration of vitamin D and omega-3 fatty acid on clinical, metabolic and genetic parameters in women with polycystic ovary syndrome (PCOS). Methods: This randomized, double-blinded, placebo-controlled clinical trial was conducted on 60 subjects, aged 18-40 years old with PCOS. Subjects were randomly allocated to take either 50,000 IU vitamin D every 2 weeks plus 2000 mg/day omega-3 fatty acid from fish oil (n = 30) or pla

The effect of Nigella sativa (black seed) on biomarkers of inflammation and oxidative stress: an updated systematic review and meta-analysis of randomized controlled trials.: Objective: This study was conducted to assess the effect of Nigella sativa (N. sativa) supplementation on inflammatory and oxidative markers among the adult population. Methods: We carried out a comprehensive, systematic search of Scopus, Embase, Cochrane Library, Web of Science, PubMed, and Google Scholar till December 2022. A random-effects model was used to estimate the overall effect size. Results: In total, twenty trials consisting of 1086 participants were included in the meta-analysis. Fi

Cumulative meta-analysis of interleukins 6 and 1β, tumour necrosis factor α and C-reactive protein in patients with major depressive disorder.: Cumulative meta-analyses are used to evaluate the extent to which further studies are needed to confirm or refute a hypothesis. We used this approach to assess observational evidence on systemic inflammation in individuals with major depressive disorder. We identified 58 studies of four common inflammatory markers in a literature search of PubMed, Embase and PsychInfo databases in May 2014. Pooled data from the earliest eight studies already showed an association between interleukin-6 concentrat

Towards a consensus definition of allostatic load: a multi-cohort, multi-system, multi-biomarker individual participant data (IPD) meta-analysis.: Background: Allostatic load (AL) is a multi-system composite index for quantifying physiological dysregulation caused by life course stressors. For over 30 years, an extensive body of research has drawn on the AL framework but has been hampered by the lack of a consistent definition. Methods: This study analyses data for 67,126 individuals aged 40-111 years participating in 13 different cohort studies and 40 biomarkers across 12 physiological systems: hypothalamic-pituitary-adrenal (HPA) axis, s

Cytokines and C-reactive protein alterations with respect to cognitive impairment in schizophrenia and bipolar disorder: A systematic review.: Background: The aim of this article was to perform a systematic review of studies investigating the association between peripheral levels of cytokines and C-reactive protein (CRP), cytokine gene polymorphisms and cognition in patients with schizophrenia and bipolar disorder (BD). Methods: The following databases: PubMed, CINAHL Complete, Academic Search Complete, ERIC and Health Source: Nursing/Academic Edition databases were searched according to the PRISMA guidelines. We included studies that

Validation of a high-sensitivity assay for C-reactive protein in human saliva.

This study aimed to validate a high-sensitivity assay for C-reactive protein (CRP) in saliva as an alternative medium to study inflammation in large epidemiological cohorts and young people. We measured CRP in saliva and serum in 61 (29.5% males) healthy adult volunteers. We found a moderate-to-strong association between CRP measured in saliva and in serum (r=.72, p<.001). In agreement with the non-steroidal structure and the high molecular weight of CRP, we observed a low saliva-to-serum CRP ratio (1:1633.64). Furthermore, a dichotomous index of salivary CRP, equivalent to a clinically relevant serum CRP cut-off (3mg/l), was associated to known correlates of systemic inflammation (IL-6, BMI and smoking). Finally, we showed that CRP in saliva is stable at room temperature up to 8h after collection. Our study provides initial evidence suggesting that non-invasive assessment of CRP in sali…

Procysteine stimulates expression of key anabolic factors and reduces plantaris atrophy in alcohol-fed rats.

Background: Long-term alcohol ingestion may produce severe oxidant stress and lead to skeletal muscle dysfunction. Emerging evidence has suggested that members of the interleukin-6 (IL-6) family of cytokines play diverse roles in the regulation of skeletal muscle mass. Thus, our goals were (i) to minimize the degree of oxidant stress and attenuate atrophy by supplementing the diets of alcohol-fed rats with the glutathione precursor, procysteine, and (ii) to identify the roles of IL-6 family members in alcoholic myopathy. Methods: Age- and gender-matched Sprague-Dawley rats were fed the Lieber-DeCarli liquid diet containing either alcohol or an isocaloric substitution (control diet) for 35 weeks. Subgroups of alcohol-fed rats received procysteine (0.35%, w/v) for the final 12 weeks. Plantaris morphology was assessed by hematoxylin and eosin staining. Major components of glutathione metabo…

Homocysteine levels and leukocyte telomere length.

Objective: Elevated plasma homocysteine is a risk factor for vascular diseases, possibly due to homocysteine-mediated increase in oxidative stress and inflammation. As leukocyte telomere length (LTL) registers the cumulative oxidative stress and inflammation, we examined the relationship between homocysteine and LTL. Methods: LTL was measured using the Southern blot method. The relationship between LTL and homocysteine levels was considered for confounding with the following covariates: age, sex, smoking, obesity, physical activity, menopause, hormone replacement therapy use and creatinine clearance. Results: 1,319 healthy subjects were recruited from a population-based cohort. LTL was negatively correlated with plasma homocysteine levels, after adjustment for smoking, obesity, physical activity, menopause, hormone replacement therapy use and creatinine clearance. The difference in multi…

Ethnobotanical knowledge is associated with indices of child health in the Bolivian Amazon.

Culture is a critical determinant of human behavior and health, and the intergenerational transmission of knowledge regarding the use of available plant resources has historically been an essential function of culture. Local ethnobotanical knowledge is important for health and nutrition, particularly in rural low-resource settings, but cultural and economic transitions associated with globalization threaten such knowledge. This prospective study investigates the association between parental ethnobotanical knowledge and child health among the Tsimane', a horticulturalist and foraging society in Amazonian Bolivia. Anthropometric data and capillary blood samples were collected from 330 Tsimane' 2- to 10-year-olds, and mothers and fathers were interviewed to assess ethnobotanical knowledge and skills. Comprehensive measures of parental schooling, acculturation, and economic activities were a…

Increased serum levels of 8-hydroxy-2'-deoxyguanosine in clinical depression.

Objective: We sought to understand the pathophysiological effects of depression by examining group differences in serum levels of 8-hydroxy-2'-deoxyguanosine (8-OHdG), a biomarker of oxidative damage. Methods: Our sample consisted of 169 participants. Eight-four of these participants met diagnostic criteria for clinical depression. The 85 participants in our comparison group were matched on age, gender, and ethnicity to the depressed group. 8-OHdG was measured by enzyme-linked immunosorbent assay. Results: After adjusting for age, gender, race/ethnicity, years of education, daily smoking, average number of alcoholic drinks per week, average amount of physical activity per week, and body mass index, participants in the depressed group had significantly higher levels of oxidative DNA damage compared with participants in the control group. Pairwise comparisons showed that participants with …

AGA Clinical Practice Update on Diet and Nutritional Therapies in Patients With Inflammatory Bowel Disease: Expert Review.

Description: Diet plays a critical role in human health, but especially for patients with inflammatory bowel disease (IBD). Guidance about diet for patients with IBD are often controversial and a source of uncertainty for many physicians and patients. The role of diet has been investigated as a risk factor for IBD etiopathogenesis and as a therapy for active disease. Dietary restrictions, along with the clinical complications of IBD, can result in malnutrition, an underrecognized condition among this patient population. The aim of this American Gastroenterological Association (AGA) Clinical Practice Update (CPU) is to provide best practice advice statements, primarily to clinical gastroenterologists, covering the topics of diet and nutritional therapies in the management of IBD, while emphasizing identification and treatment of malnutrition in these patients. We provide guidance for tail…

Using social risk factors to predict allostatic biotypes of depression: A latent profile and multinomial regression analysis.

Objective: Major depression is often difficult to treat, particularly among individuals exposed to psychosocial risks like childhood maltreatment, loneliness, and recent stress. These experiences may lead to biological dysregulation consistent with allostatic load theory. This study explored whether distinct biological profiles among adults with depression are associated with specific psychosocial and health-related factors. Method: Data were drawn from the Midlife in the United States study (MIDUS), including 367 participants with clinically significant depressive symptoms (CES-D ≥ 16). Latent profile analysis identified biological profiles based on 23 biomarkers across seven systems: inflammation, glucose, sympathetic and parasympathetic nervous systems, HPA-axis, cardiovascular, and lipids. Multinomial regression models examined associations between profile membership and psychosocial…

Association of dietary inflammatory potential, dietary oxidative balance score and biological aging.

Background & aims: The interaction between diet, inflammation, and oxidative stress significantly influences aging, but the available evidence has been limited. We evaluated potential associations of dietary inflammatory index (DII), dietary oxidative balance score (DOBS), and measures of biological aging. Methods: This cross-sectional study was performed among 8839 individuals from NHANES 2003-2014. DII and DOBS were determined by aggregating data from 26 to 17 a priori selected dietary components. Biological aging metrics included homeostatic dysregulation (HD), Klemera-Doubal method (KDM), phenotypic age (PA), and allostatic load (AL). Binomial logistic regression models and multivariate linear regression models were conducted. Results: The associations of dietary inflammation and oxidative stress potential and biological aging metrics were significant among American adults nationwide…

Sex differences in age trajectories of physiological dysregulation: inflammation, metabolic syndrome, and allostatic load.

There is a paucity of knowledge from population data about sex differences and their age variation in physiological determinants of longevity. This study fills this gap using nationally representative samples of 38,000 individuals aged 17+ from the National Health and Nutrition Examination Survey (1988-2006). It examines sex differences in the age trajectories of 14 markers of physiological functions across multiple systems and three summary indices including inflammation burden, metabolic syndrome, and allostatic load. Statistical analyses show substantial sex differences, age variations, and sex by age interaction effects for all variables examined. These patterns remain robust after adjustment of risk factors and shed light on the biological base of the reduction of sex difference in mortality in the post-reproductive life span.

Psychoneuroimmunology of Mood Disorders.

Recent research has shed light on the intricate relationship between mood disorders, such as major depressive disorder (MDD) and bipolar disorder (BD), and inflammation. This chapter explores the complex interplay involving immune and metabolic dysfunction in the pathophysiology of these disorders, emphasizing their association with autoimmunity/inflammatory conditions, chronic low-grade systemic inflammation, T cell overactivation, and immunosenescence. This perspective underscores the notion that MDD and BD are not solely brain disorders, highlighting their nature as multi-system conditions.

Oxytocin and oxygen: the evolution of a solution to the 'stress of life'.

Oxytocin (OT) and the OT receptor occupy essential roles in our current understanding of mammalian evolution, survival, sociality and reproduction. This narrative review examines the hypothesis that many functions attributed to OT can be traced back to conditions on early Earth, including challenges associated with managing life in the presence of oxygen and other basic elements, including sulfur. OT regulates oxidative stress and inflammation especially through effects on the mitochondria. A related nonapeptide, vasopressin, as well as molecules in the hypothalamic-pituitary-adrenal axis, including the corticotropin-releasing hormone family of molecules, have a broad set of functions that interact with OT. Interactions among these molecules have roles in the causes and consequence of social behaviour and the management of threat, fear and stress. Here, we discuss emerging evidence sugge…

Polycystic ovarian syndrome (PCOS) is a prevailing endocrine and metabolic disorder occurring in about 6-20% of females in reproductive age. Most symptoms of PCOS arise early during puberty. Since PCOS involves a combination of signs and symptoms, thus it is considered as a heterogeneous disorderliness. The most accepted diagnostic criteria is Rotterdam criteria which involves two of the latter three features: (a) hyperandrogenism, (b) oligo- or an-ovulation, and (c) polycystic ovaries. The persistent hormonal imbalance leads to multiple small antral follicles formation and irregular menstrual cycle, ultimately causing infertility among females. Insulin resistance, cardiovascular diseases, abdominal obesity, psychological disorders, infertility, and cancer are also related to PCOS. These pathophysiologies associated with PCOS are interrelated with each other. Hyperandrogenism causes insu…

Basic Concept of Microglia Biology and Neuroinflammation in Relation to Psychiatry.

The hypothesis that the neuroimmune system plays a role in the pathogenesis of different psychiatric disorders, including schizophrenia, depression, and bipolar disease, has attained increasing interest over the past years. Previously thought to have the sole purpose of protecting the central nervous system (CNS) from harmful stimuli, it is now known that the central immune system is critically involved in regulating physiological processes including neurodevelopment, synaptic plasticity, and circuit maintenance. Hence, alterations in microglia - the main immune cell of the CNS - and/or inflammatory factors do not unequivocally connote ongoing neuroinflammation or neuroinflammatory processes per se but rather might signify changes in brain homoeostasis. Despite this, psychiatric research tends to equate functional changes in microglia or alterations in other immune mediators with neuroin…

Stress, sex hormones, inflammation, and major depressive disorder: Extending Social Signal Transduction Theory of Depression to account for sex differences in mood disorders.

Social Signal Transduction Theory of Depression is a biologically plausible, multi-level theory that describes neural, physiologic, molecular, and genomic mechanisms that link experiences of social-environmental adversity with internal biological processes that drive depression pathogenesis, maintenance, and recurrence. Central to this theory is the hypothesis that interpersonal stressors involving social threat (e.g., social conflict, evaluation, rejection, isolation, and exclusion) upregulate inflammatory processes that can induce several depressive symptoms, including sad mood, anhedonia, fatigue, psychomotor retardation, and social-behavioral withdrawal. The original article describing this formulation (Psychol Bull 140:774-815, 2014) addressed critical questions involving depression onset and recurrence, as well as why depression is strongly predicted by early life stress and comorb…

The influence of neuroinflammation in Autism Spectrum Disorder.

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterised by deficits in social communication and restricted or repetitive behaviours. The clinical presentation of ASD is highly variable and diagnosis is based on the presence of impaired social communication and repetitive and/or restricted behaviours. Although the precise pathophysiologies underlying ASD are unclear, growing evidence supports a role for dysregulated neuroinflammation. The potential involvement of microglia and astrocytes reactive to inflammatory stimuli in ASD has generated much interest due to their varied roles including in mounting an immune response and regulating synaptic function. Increased numbers of reactive microglial and astrocytes in both ASD postmortem tissue and animal models have been reported. Whether dysregulation of glial subtypes exacerbates alterations in neural connectivity in the…

Inflammation and depression: a causal or coincidental link to the pathophysiology?

This review summarises the evidence that chronic low grade inflammation triggers changes that contribute to the mental and physical ill health of patients with major depression. Inflammation, and the activation of the hypothalamic pituitary axis by stress, are normal components of the stress response but when stress is prolonged and the endocrine and immune system become chronic resulting in the activation of the peripheral macrophages, the central microglia and hypercortisolemia, the neuronal networks are damaged and become dysfunctional. The proinflammatory cytokines, in addition to activating the hypothalamic-pituitary-adrenal axis and thereby increasing cortisol synthesis, also activate the tryptophan-kynurenine pathway. This results in the synthesis of the neurotoxic N-methyl-d-aspartate (NMDA) glutamate agonist quinolinic acid and 3-hydroxykynurenine thereby enhancing oxidative str…

Why are depressed patients inflamed? A reflection on 20 years of research on depression, glucocorticoid resistance and inflammation.

Studies over the last 20 years have demonstrated that increased inflammation and hyperactivity of the hypothalamic-pituitary-adrenal (HPA) axis are two of the most consistent biological findings in major depression and are often associated: but the molecular and clinical mechanisms underlying these abnormalities are still unclear. These findings are particularly enigmatic, especially considering the accepted notion that high levels of cortisol have an anti-inflammatory action, and therefore the coexistence of inflammation and hypercortisolemia in the same diagnostic group appears counter-intuitive. To celebrate the 2015 Anna-Monika Foundation Award to our laboratory, this review will discuss our own 20 years of research on the clinical and molecular evidence underlying the increased inflammation in depression, especially in the context of a hyperactive HPA axis, and discuss its implicati…

Contribution of neuroinflammation and immunity to brain aging and the mitigating effects of physical and cognitive interventions.

It is widely accepted that the brain and the immune system continuously interact during normal as well as pathological functioning. Human aging is commonly accompanied by low-grade inflammation in both the immune and central nervous systems, thought to contribute to many age-related diseases. This review of the current literature focuses first on the normal neuroimmune interactions occurring in the brain, which promote learning, memory and neuroplasticity. Further, we discuss the protective and dynamic role of barriers to neuroimmune interactions, which have become clearer with the recent discovery of the meningeal lymphatic system. Next, we consider age-related changes of the immune system and possible deleterious influences of immunosenescence and low-grade inflammation (inflammaging) on neurodegenerative processes in the normally aging brain. We survey the major immunomodulators and n…

Psychedelics as Medicines: An Emerging New Paradigm.

Scientific interest in serotonergic psychedelics (e.g., psilocybin and LSD; 5-HT2A receptor agonists) has dramatically increased within the last decade. Clinical studies administering psychedelics with psychotherapy have shown preliminary evidence of robust efficacy in treating anxiety and depression, as well as addiction to tobacco and alcohol. Moreover, recent research has suggested that these compounds have potential efficacy against inflammatory diseases through novel mechanisms, with potential advantages over existing antiinflammatory agents. We propose that psychedelics exert therapeutic effects for psychiatric disorders by acutely destabilizing local brain network hubs and global network connectivity via amplification of neuronal avalanches, providing the occasion for brain network "resetting" after the acute effects have resolved. Antiinflammatory effects may hold promise for eff…

Inflammasomes, hormesis, and antioxidants in neuroinflammation: Role of NRLP3 in Alzheimer disease.

Alzheimer disease (AD) is a progressive neurodegenerative disorder leading to cognitive decline, neuropsychiatric symptoms, disability, caregiver burden, and premature death. It represents the most prevalent cause of dementia, and its incidence rates exponentially increase with increasing age. The number of Americans living with AD is rapidly increasing. An estimated 5.4 million Americans of all ages have AD in 2016. One in nine people aged 65 and older has AD, and by midcentury, someone in the United States will develop the disease every 33 sec. It is now accepted that neuroinflammation is a common feature of neurological disease. Inflammasomes, which are a multiprotein complex part of the innate immune system, induce inflammation in response to various stimuli, such as pathogens and stress. Inflammasomes activate proinflammatory caspases, such as caspase-1, leading to the activation of…

N-3 polyunsaturated fatty acids in animal models with neuroinflammation: An update.

Neuroinflammation is a characteristic of a multitude of neurological and psychiatric disorders. Modulating inflammatory pathways offers a potential therapeutic target in these disorders. Omega-3 polyunsaturated fatty acids have anti-inflammatory and pro-resolving properties in the periphery, however, their effect on neuroinflammation is less studied. This review summarizes 61 animal studies that tested the effect of omega-3 polyunsaturated fatty acids on neuroinflammatory outcomes in vivo in various models including stroke, spinal cord injury, aging, Alzheimer's disease, Parkinson's disease, lipopolysaccharide and IL-1β injections, diabetes, neuropathic pain, traumatic brain injury, depression, surgically induced cognitive decline, whole body irradiation, amyotrophic lateral sclerosis, N-methyl-D-aspartate-induced excitotoxicity and lupus. The evidence presented in this review suggests a…

The resolution code of acute inflammation: Novel pro-resolving lipid mediators in resolution.

Studies into the mechanisms in resolution of self-limited inflammation and acute reperfusion injury have uncovered a new genus of pro-resolving lipid mediators coined specialized pro-resolving mediators (SPM) including lipoxins, resolvins, protectins and maresins that are each temporally produced by resolving-exudates with distinct actions for return to homeostasis. SPM evoke potent anti-inflammatory and novel pro-resolving mechanisms as well as enhance microbial clearance. While born in inflammation-resolution, SPM are conserved structures with functions discovered in microbial defense, pain, organ protection and tissue regeneration, wound healing, cancer, reproduction, and neurobiology-cognition. This review covers these SPM mechanisms and other new omega-3 PUFA pathways that open their path for functions in resolution physiology.

The paradox of chronic neuroinflammation, systemic immune suppression, autoimmunity after traumatic chronic spinal cord injury.

During the transition from acute to chronic stages of recovery after spinal cord injury (SCI), there is an evolving state of immunologic dysfunction that exacerbates the problems associated with the more clinically obvious neurologic deficits. Since injury directly affects cells embedded within the "immune privileged/specialized" milieu of the spinal cord, maladaptive or inefficient responses are likely to occur. Collectively, these responses qualify as part of the continuum of "SCI disease" and are important therapeutic targets to improve neural repair and neurological outcome. Generic immune suppressive therapies have been largely unsuccessful, mostly because inflammation and immunity exert both beneficial (plasticity enhancing) and detrimental (e.g. glia- and neurodegenerative; secondary damage) effects and these functions change over time. Moreover, "compartimentalized" investigation…

Neurogenesis, inflammation and behavior.

Before the 1990s it was widely believed that the adult brain was incapable of regenerating neurons. However, it is now established that new neurons are continuously produced in the dentate gyrus of the hippocampus and olfactory bulb throughout life. The functional significance of adult neurogenesis is still unclear, but it is widely believed that the new neurons contribute to learning and memory and/or maintenance of brain regions by replacing dead or dying cells. Many different factors are known to regulate adult neurogenesis including immune responses and signaling molecules released by immune cells in the brain. While immune activation (i.e., enlargement of microglia, release of cytokines) within the brain is commonly viewed as a harmful event, the impact of immune activation on neural function is highly dependent on the form of the immune response as microglia and other immune-reacti…
