In this review, we aim to provide a comprehensive summary of the current knowled Dysregulation of the NLRP3 inflammasome has been implicated in the progression of several neurodegenerative disorders, such as Alzheimer's disease, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, and prion diseases
NLRP3 -associated autoinflammatory diseases (NLRP3 -AIDs) include conditions of various severities, due to germline or somatic mosaic NLRP3 mutations However, NLRP3 inflammasome-mediated inflammatory cytokines play dual roles in mediating human disease. While they are detrimental in the pathogenesis of inflammatory and metabolic diseases, they.. Once activated, NLRP3 nucleates the assembly of an inflammasome, leading to caspase 1-mediated proteolytic activation of the interleukin-1β (IL-1β) family of cytokines, and induces an inflammatory,.. Neonatal onset multisystem inflammatory disease (NOMID) is a genetic disease, often caused by mutations in the NLRP3 (also known as CIAS1) gene. In almost all cases, NOMID results from new mutations within this gene. These cases occur in people with no history of the disorder in their family (de novo)
The NLRP3 inflammasome has been implicated in a wide range of diseases, including Alzheimer's disease, Prion diseases, type 2 diabetes, and some infectious diseases In recent years, our understanding of NLRP3 inflammasome activation and regulation has rapidly progressed, leading the way to new developments in potential therapeutics for several autoinflammatory diseases (Caseley et al., 2020).This review aims to summarise recent progress in our understanding of several neurodegenerative diseases, whose development and/or progression has been linked to.
Neuroinflammation has been identified as a causative factor of multiple neurological diseases. The nucleotide-binding oligomerization domain-, leucine-rich repeat- and pyrin domain-containing 3 (NLRP3) inflammasome, a subcellular multiprotein complex that is abundantly expressed in the central nervous system (CNS), can sense and be activated by a wide range of exogenous and endogenous stimuli.

In this study, we showed that TR directly bound to NLRP3 and inhibited NLRP3 inflammasome assembly and the subsequent caspase-1 activation and IL-1b production. More importantly, TR could prevent or treat NLRP3-dependent inflammatory. NLRP3 inflammasome is a part of the innate immune system and responsible for the rapid identification and eradication of pathogenic microbes, metabolic stress products, reactive oxygen species, and other exogenous agents. NLRP3 inflammasome is overactivated in several neurodegenerative, cardiac, pulmonary, and metabolic diseases. Therefore, suppression of inflammasome activation is of utmost.
Due to the effects of the NLRP3 genetic mutation causing this syndrome, there is a chance of some inflammation developing while the baby is still in the mother's womb. Most NOMID patients are born with uneventful deliveries or pregnancies, but at birth or shortly after in the neonatal period develop severe NOMID symptoms, usually starting with. NLRP3 (NOD-, LRR- and pyrin domain-containing 3) is the primary sensor for inflammatory signals caused by aging, physical inactivity, over-nutrition or environmental factors. NLRP3 can be the cause of chronic diseases because it acts as a whistleblower, passing danger signals downstream to initiate chronic inflammatory tissue reactions.

Activation of the NLRP3 inflammasome in the body is implicated in many diseases caused by chronic, uncontrolled inflammation. Inflammasomes are understood to drive many chronic inflammatory conditions, from Parkinson's and Alzheimer's to asthma, inflammatory bowel disease, chronic kidney disease, cardiovascular disease, arthritis and NASH Muckle-Wells Syndrome (MWS) is a form of CAPS that is caused by genetic mutations on the NLRP3 (CIAS1) gene that encodes the cryopyrin protein. MWS can be caused by a spontaneous mutation of the NLRP3 gene; but in most cases the genetic mutation has been passed along for generations in families. The NLRP3 mutation is autosomal dominant, which means that if one parent has the NLRP3 mutation and. Whether NLRP3 is a transcription or epigenetic factor that affects differentiation and function of epithelial and mesothelial cells to more abnormal cell types culminating in malignant or nonmalignant lung diseases is an unexplored area Increased activation of NLRP3 has been related to several chronic pathologies, including neurodegenerative and cardiovascular diseases, diabetes, fibrosis and rheumatoid arthritis.
