Acidic Environment Induces Pyroptosis of NLRP3 Inflammatory Vesicle-Mediated Nucleus Pulposus Cells Through Up-Regulation of POSTN Expression

Int. j. morphol; 41 (6), 2023
SUMMARY: Intervertebral disc degeneration (IVDD) is induced by nucleus pulposus (NP) dysfunction as a result of massive loss of NP cells. It has been reported that the acidic microenvironment of the intervertebral disc (IVD) can induce NP cell pyroptosis, and that up-regulation of periostin (POSTN) expre...

Diacerein mitigates renal ischemia/reperfusion injury via inhibition of renal inflammation, dendritic cells maturation and apoptosis: the role of TLR4/NF-kB/NLRP3/IL-1beta signaling pathway

Int. j. morphol; 41 (2), 2023
SUMMARY: One of the reasons for acute kidney damage is renal ischemia. Nevertheless, there are limited protective and therapeutic approaches for this problem. Diacerein is an anti-inflammatory drug characterized by numerous biological activities. We aimed to determine the ameliorative impact of diacerein...

Protective effect of Guanxin Danshen formula on myocardial ischemiareperfusion injury in rats

Acta cir. bras; 38 (), 2023
Purpose: Myocardial ischemia/reperfusion injury (MIRI) leads to myocardial tissue necrosis, which will increase the size of myocardial infarction. The study examined the protective effect and mechanism of the Guanxin Danshen formula (GXDSF) on MIRI in rats. Methods: MIRI model was performed in rats; rat ...

NLRP3 inflammasome inhibitor MCC950 can reduce the damage of pancreatic and intestinal barrier function in mice with acute pancreatitis

Acta cir. bras; 37 (7), 2022
Purpose: Abnormal activation of NOD-like receptor protein 3 (NLRP3) inflammasome can lead to the occurrence and progression of acute pancreatitis. This study investigated the protective effect of MCC950 on pancreatitis mice. Methods: Eighteen mice were randomly divided into control group, severe acute p...

Tanshinone IIA ameliorates myocardial ischemia/reperfusion injury in rats by regulation of NLRP3 inflammasome activation and Th17 cells differentiation

Acta cir. bras; 37 (7), 2022
Purpose: Tanshinone IIA is a well-known lipophilic active constituent refined from traditional Chinese medicines, danshen. It has been previously demonstrated to possess various biological properties, including anti-inflammatory, antioxidant, promoting angiogenesis effect and so on. However, the mechanis...

High glucose induces pyroptosis of retinal microglia through NLPR3 inflammasome signaling

Arq. bras. oftalmol; 84 (1), 2021
ABSTRACT Purpose: Diabetic retinopathy is currently considered a chronic inflammatory disease involving NOD-like receptor family pyrin domain containing 3 inflammasome activation and retinal microglial pyroptosis. In this study, we aimed to investigate whether NOD-like receptor family pyrin domain conta...

Impacto funcional de la inhibición farmacológica de Tmem176b en diferentes subpoblaciones de células dendríticas

Nuestro grupo ha reportado que la proteína Tmem176b es un canal/transportador iónico intracelular fuertemente expresado en células dendríticas (DCs), que bloquea la respuesta inmune anti-tumoral. Identificamos al compuesto BayK8644 como un inhibidor de Tmem176b. BayK8644 promueve el control tumoral e...

Paeoniflorin mitigates PBC-induced liver fibrosis by repressing NLRP3 formation

Acta cir. bras; 36 (11), 2021
ABSTRACT Purpose: To delve into the influence of paeoniflorin (PA) on abating primary biliary cholangitis (PBC)-induced liver fibrosis and its causative role. Methods: Our team allocated the mice to control group, PA group, PBC group and PBC+PA group. We recorded the weight change of mice in each group...

Expression of NLRP3 inflammasome in leprosy indicates immune evasion of Mycobacterium leprae

Mem. Inst. Oswaldo Cruz; 115 (), 2020
BACKGROUND Leprosy is an infectious-contagious disease caused by Mycobacterium leprae that remain endemic in 105 countries. This neglected disease has a wide range of clinical and histopathological manifestations that are related to the host inflammatory and immune responses. More recently, the inflamma...

Baicalin suppresses Propionibacterium acnes-induced skin inflammation by downregulating the NF-κB/MAPK signaling pathway and inhibiting activation of NLRP3 inflammasome

Braz. j. med. biol. res; 53 (12), 2020
Acne is a kind of common, chronic skin condition caused by the inflammation of the sebaceous glands in hair follicles. Recent studies have demonstrated that baicalin (BA) possesses potential anti-inflammatory properties. In this study, we evaluated the anti-inflammatory activity of BA in vitro and in viv...
