The use of Trametes robiniophila Murr. (Huaier) as a complementary therapy for cancer has recently become increasingly common in China. However, whether Huaier can regulate host immune responses, especially innate immunity, remains largely unknown. The NLRP3 inflammasome is a multimeric complex consisting of NLRP3, ASC and caspase-1. NLRP3 inflammasomes respond to a variety of endogenous (damag...

BACKGROUND/AIMS Primary glomerulonephritis (PGN) is the most common reason inducing end stage renal disease in China, however, its pathogenesis remains unclear. The present study was designed to test the hypothesis that the formation and activation of NLRP3 (Nod-like receptor family pyrin domain containing 3) inflammasomes is an important initiating mechanism resulting in PGN. METHODS Serum s...

BACKGROUND Nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome is associated with metabolic disorder and cell death, which are important triggers in diabetic cardiomyopathy (DCM). We aimed to explore whether NLRP3 inflammasome activation contributes to DCM and the mechanism involved. METHODS Type 2 diabetic rat model was induced by high fat diet and low dose...

Excessive activation of the NLRP3 inflammasome results in damaging inflammation, yet the regulators of this process remain poorly defined. Herein, we show that the orphan nuclear receptor small heterodimer partner (SHP) is a negative regulator of NLRP3 inflammasome activation. NLRP3 inflammasome activation leads to an interaction between SHP and NLRP3, proteins that are both recruited to mitoch...

The Nod-like receptor NLRP3 is involved in the formation of NLRP3. Up to now, the immunological functions of NLRP3 independently of inflammasome is unclear. In this dataset containing 6 samples (TH0, TH2 cells at day 3 and day 6 in wild type or Nlrp3 deficient cells), we show that NLRP3 expression in CD4(+) T cells supports a T helper 2 (TH2) transcriptional program in a cell-intrinsic manner (...

BACKGROUND Chronic obstructive pulmonary disease (COPD) is now recognized as an inflammatory disease and the nucleotide-binding oligomerization domain-like receptor 3 (NLRP3) inflammasome was speculated to participate into its pathophysiological process, however, a direct role of NLRP3 has yet to be clearly shown. METHOD COPD model was established by tobacco inhalation, COPD modeling and NLRP...

IL-1β production is critically regulated by cytosolic molecular complexes, termed inflammasomes. Different inflammasome complexes have been described to date. While all inflammasomes recognize certain pathogens, it is the distinctive feature of NLRP3 inflammasome to be activated by many and diverse stimuli making NLRP3 the most versatile, and importantly also the most clinically implicated infl...

The NLRP3 inflammasome plays a critical role in host defense by facilitating caspase I activation and maturation of IL-1β and IL-18, whereas dysregulation of inflammasome activity results in autoinflammatory disease. Factors regulating human NLRP3 activity that contribute to the phenotypic heterogeneity of NLRP3-related diseases have largely been inferred from the study of Nlrp3 mutant mice. By...

Growing evidence has shown that NLRP3 inflammasome activation promotes the development of tubularinterstitial inflammation and progression of renal injury. We previously found that mitochondrial dysfunction is a critical determinant for the activation of NLRP3 inflammasome in albumin-overload rats. Angiotensin (Ang) II plays an important role in mitochondrial homeostasis. Here, we investigated ...

NOD-like receptor (NLR) NLRP3 inflammasome activation has been implicated in the progression of non-alcoholic fatty liver disease (NAFLD) from non-alcoholic fatty liver (NAFL) to non-alcoholic steatohepatitis (NASH). It has been also shown that palmitic acid (PA) activates NLRP3 inflammasome and promotes interleukin-1β (IL-1β) secretion in Kupffer cells (KCs). However, the specific mechanism of...
