Macrophages and microglia play a key role in the maintenance of nervous system homeostasis. However, upon different challenges, they can adopt several phenotypes, which may lead to divergent effects on tissue repair. After spinal cord injury (SCI), macrophages show predominantly pro-inflammatory activation contribute damage. factors that hamper their conversion an anti-inflammatory state after SCI, or other protective are poorly understood. Here, we IL-4 protein levels undetectable contusion...
Abstract Background Parkinson’s disease (PD) is characterized by a progressive degeneration of dopaminergic neurons, which leads to irreversible loss peripheral motor functions. Death neurons induces an inflammatory response in microglial cells, further exacerbates neuronal loss. Reducing inflammation expected ameliorate and arrest dysfunctions. Because the contribution NLRP3 inflammasome PD, we targeted using specific inhibitor OLT1177 ® . Methods We evaluated effectiveness reducing MPTP...
Spinal cord injury (SCI) usually causes a devastating lifelong disability for patients. After traumatic lesion, disruption of the blood-spinal barrier induces infiltration macrophages into lesion site and activation resident glial cells, which release cytokines chemokines. These events result in persistent inflammation, has both detrimental beneficial effects, but eventually limits functional recovery contributes to appearance neuropathic pain. Bromodomain extra-terminal domain (BET)...
The IL-1 family member IL-37 broadly suppresses innate inflammation and acquired immunity. Similar to IL-1α IL-33, is a dual-function cytokine in that translocates the nucleus but also transmits signal via surface membrane receptors. role of nuclear remains unknown on ability this inhibit inflammation. Here, we compared suppression transgenic mice expressing native human (IL-37Tg) with those carrying mutation aspartic acid (D) alanine (A) at amino 20 (IL-37D20ATg). D20A prevents cleavage...
Background: Microglia and macrophages adopt a pro-inflammatory phenotype after spinal cord injury (SCI), what is thought to contribute secondary tissue degeneration.We previously reported that this due, in part, the low levels of anti-inflammatory cytokines, such as IL-4.Since IL-13 IL-4 share receptors both cytokines drive microglia towards an vitro, here we studied whether administration SCI leads beneficial effects.Methods: We injected mice with recombinant or at 48 h assessed their...
A role for microglia in neuropsychiatric diseases, including major depressive disorder (MDD), has been postulated. Regulation of microglial phenotype by immune receptors become a central topic many neurological conditions. We explored preclinical and clinical evidence the CD300f receptor fine regulation its contribution to MDD. found that prevalent nonsynonymous single-nucleotide polymorphism (C/T, rs2034310) human cytoplasmic tail inhibits protein kinase C phosphorylation threonine is...
Background: Interleukin 37 (IL-37), a member of IL-1 family, broadly suppresses inflammation in many pathological conditions by acting as dual-function cytokine that IL-37 signals via the extracellular receptor complex IL1-R5/IL-1R8, but it can also translocate to nucleus. However, whether exerts beneficial actions neuroinflammatory diseases, such multiple sclerosis, remains be elucidated. Thus, goals present study were evaluate therapeutic effects mouse model and if so, this is mediated...
IL-38 is a recently discovered cytokine and member of the IL-1 Family. In Family, unique because primarily B lymphocyte product functions to suppress inflammation. Studies in humans with inflammatory bowel disease (IBD) suggest that may be protective for ulcerative colitis or Crohn’s disease, acts maintain homeostasis intestinal tract. Here we investigated role endogenous experimental mice deficient by deletion exons 1-4 C57 BL/6 mice. Compared WT mice, subjected dextran sulfate sodium (DSS)...

In this study, we report PDAC cells release CSF-1 induce nucleotide-binding domain, leucine-rich containing family, pyrin domain-containing-3 (NLRP3) activation myeloid cells. Increased NLRP3 expression was found pancreas patients with when compared normal correlated...
Abstract Spinal cord injury (SCI) leads to irreversible devastating neurological disabilities. Accumulated evidence in the literature indicates that inflammatory response occurs spinal following contributes importantly spread tissue damage healthy regions adjacent lesion site, and consequently, increase deficits. Therefore, targeting inflammation could lead development of new therapies prevent impairments after SCI. Inflammation is regulated, part, by expression pro‐inflammatory...
Introduction Interleukin-18 (IL-18), a pro-inflammatory cytokine belonging to the IL-1 Family, is key mediator ofautoinflammatory diseases associated with development of macrophage activation syndrome (MAS).High levels IL-18 correlate MAS and COVID-19 severity mortality, particularly in COVID-19patients MAS. As an inflammation inducer, binds its receptor Receptor 5 (IL-1R5), leadingto recruitment co-receptor, 7 (IL-1R7). This heterotrimeric complex subsequentlyinitiates downstream signaling,...
The IL-1 Family member IL-38 has been characterized primarily as an antiinflammatory cytokine in human and mouse models of systemic diseases. Here, we examined the role murine small intestine (SI). Immunostaining SI revealed that expression partially confines to intestinal stem cells. Cultures organoids reveal functions a growth factor by increasing organoid size via inducing WNT3a. In contrast, from IL-38-deficient mice develop more slowly. This reduction is likely due downregulation...
Metabolism is a fundamental process by which biochemicals are broken down to produce energy (catabolism) or used build macromolecules (anabolism). has received renewed attention as mechanism that generates molecules modulate multiple cellular responses. This was first identified in cancer cells the Warburg effect, but it also present immunocompetent cells. Studies have revealed bidirectional influence of metabolism and immune cell function, highlighting significance metabolic reprogramming...
Activating and inhibitory immune receptors play a critical role in regulating systemic central nervous system (CNS) inflammatory processes. The CD200R1 immunoreceptor induces restraining signal modulating inflammation phagocytosis the CNS under different conditions. However, it remains unknown whether has response after peripheral nerve injury, an essential component of successful regeneration. Expression its ligand CD200 was analyzed during homeostasis sciatic crush injury C57Bl/6 mice....
