alzheimer's disease (ad), the most ordinary form of dementia and extracellular accumulation of amyloid-β (aβ) in senile plaques, is an important and a main event in the pathogenesis of ad. deposition of aβ peptide initiates a spectrum of cellular responses that are interposed by the resident neuroimmune cells of the brain, the microglia. recently, a novel inflammasome signaling  pathway ha...

Background: Hemin is an important sterile component that induces a neuroinflammatory response after intracerebral hemorrhage, in which NLRP3 inflammasome activation has also proved to be involved. Although microglial activation acts as a key contributor in the neuroinflammatory response, the relationship between hemin and NLRP3 in microglia remains poorly understood. Objective: To investigate w...

Hyperhomocysteinemia (HHcy) has been shown to promote vascular inflammation and atherosclerosis, but the underlying mechanisms remain largely unknown. The NLRP3 inflammasome has been identified as the cellular machinery responsible for activation of inflammatory processes. In this study, we hypothesized that the activation of NLRP3 inflammasomes contributes to HHcy-induced inflammation and athe...

NLRP3 is a cytosolic pattern recognition receptor that senses microbes and endogenous danger signals. Upon activation, NLRP3 forms an inflammasome with the adapter ASC, resulting in caspase-1 activation, release of proinflammatory cytokines and cell death. How NLRP3 activation is regulated by transcriptional and posttranslational mechanisms to prevent aberrant activation remains incompletely un...

The release of cytochrome c from the inner mitochondrial membrane, where it is anchored by caridolipin, triggers the formation of the Apaf-1 apoptosome. Cardiolipin also interacts with NLRP3 recruiting NLRP3 to mitochondria and facilitating inflammasome assembly. In this study we investigated whether cytosolic cytochrome c impacts NLRP3 inflammasome activation in macrophages. We report that cyt...

il-1β and il-17a are two cytokines with strong proinflammatory activities and are now known to be involved in a number of chronic inflammatory disorders. high-mobility group box 1 (hmgb1) is a nuclear protein regulating the expression of these proinflammatory cytokines. the nlrp3 inflammasome promotes the maturation of the il-1β and its activation has been shown as a critical mechanism in the p...

The NLRP3 inflammasome has a fundamental role in host defence against microbial pathogens and its deregulation may cause diverse inflammatory diseases. NLRP3 protein expression is a rate-limiting step for inflammasome activation, thus its expression must be tightly controlled to maintain immune homeostasis and avoid detrimental effects. However, how NLRP3 expression is regulated remains largely...

NLRP3 inflammasome has emerged as a key regulator of glucose and insulin homeostasis. Several studies have shown that activation of the NLRP3 inflammasome contributes to obesityinduced inflammation and insulin resistance [1]. Increased oxidative stress may also contribute to NLRP3 inflammasome activation during diabetes and its complications [2]. The NLRP3 inflammasome is a complexe that consis...

NLRP3 inflammasomes recognize non-microbial danger signals and induce release of proinflammatory cytokine interleukin (IL)-1β, leading to sterile inflammation in cardiovascular disease. Because sterile inflammation is involved in doxorubicin (Dox)-induced cardiotoxicity, we investigated the role of NLRP3 inflammasomes in Dox-induced cardiotoxicity. Cardiac dysfunction and injury were induced by...
