- |||||||||| Preclinical, Journal: NKT cells promote both type 1 and type 2 inflammatory responses in a mouse model of liver fibrosis. (Pubmed Central) - May 5, 2021
The induction of the type 1 inflammatory response was followed by an altered cytokine profile of the tgNKT cell population with a biased production of anti-inflammatory/profibrotic cytokines and development of liver fibrosis. These findings illustrate how the plasticity of NKT cells modulates the inflammatory response, suggesting a key role for the NKT cell population in the control of sterile liver inflammation.

In addition, compared with the LPS group, IL-32 knockdown significantly inhibited LPS-induced enhancement of cell proliferation, cell apoptosis, GSDMD activation and production of inflammatory cytokines, and reversed the increased protein expression of NLRP3, cleaved-caspase-1, activated GSDMD, NOD1/2 and TLR4. In conclusion, IL-32 may play a role in the progression of AH via promoting inflammation, and the potential mechanism may involve the activation of NLRP3-mediated pyroptosis.

[VIRTUAL] Multiple mediators of inflammation correlate with IRAK4 expression in the skin of Hidradenitis Suppurativa patients and are blocked by the IRAK4 protein degrader KT-474 in TLR-activated monocytes () - May 4, 2021 - Abstract #SID2021SID_907; The upregulation of many of these same genes in human monocytes stimulated ex vivo with the TLR7/8 agonist R848 was blocked by KT-474, including IL-1β, TNF-α, IL-6, IL-8, NLRP3, PTGS2, CXCL2/3, IRF7, IFN-γ, IL- 2RA, granzyme B and perforin. These findings suggest a central role for IRAK4 in the pleiotropic inflammation in HS, and support the development of KT-474, currently in Phase 1 testing in healthy volunteers and patients with HS or AD.

Lastly, we observed that mice fed high fat diet have high expression of NLRP3 and a greater secretion of PCSK9 than mice fed a standard diet, and this increased secretion of PCSK9 in high fat diet-fed mice was attenuated in IL-1β mice. This study based on extensive in vitro and in vivo data provides evidence that NLRP3 inflammasome via IL-1β plays an important role in determining PCSK9 secretion, particularly in the presence of high-fat diet.
- |||||||||| Journal: Cholesterol Crystals and NLRP3 Mediated Inflammation in the Uterine Wall Decidua in Normal and Preeclamptic Pregnancies. (Pubmed Central) - May 4, 2021
Preeclampsia without FGR was associated with increased trophoblast dependent NLRP3 and IL-1β expression, particularly in the decidual areas of trophoblast and leukocyte proximity. Our findings suggest that decidual accumulation of cholesterol crystals may activate the NLRP3 inflammasome and contribute to decidual inflammation and that this pathway is strengthened in areas with close maternal-fetal interaction in preeclampsia without FGR.
- |||||||||| Journal: Mechanism of scavenger receptor-A in high glucose-induced inflammatory injury of mesangial cells (Pubmed Central) - May 4, 2021
In high glucose siNC group, the NLRP3, IL-1β proteins, the NLRP3, Caspase-1 and IL-1β mRNA, all of the mRNA levels of FN, ColⅣ, α-SMA, GRP78 and the proportion of DNA synthesis phase were all higher than those in high glucose siSR-A group and normal glucose siNC group (all P<0.05). High glucose can promote abnormal cell proliferation, increase mesangial matrix production and enhance oxidative stress response through upregulating SR-A expression, and ultimately aggravate cellular inflammatory damage in HMC, which may be associated with NLRP3-Caspase-1-IL-1β pathway regulated by SR-A expression.

In this review, we focus on the role of pyroptosis in cardiovascular diseases including atherosclerosis, coronary heart disease, myocardial infarction, diabetic cardiomyopathy, pressure overload-induced ventricular remodeling and cardiac hypertrophy, myocarditis, arrhythmia and so on, and summarize the potential treatment targeting pyroptosis. It will provide the basis for prevention and treatment of clinical cardiovascular diseases.

Moreover, serum levels of the inflammatory factor, IL-1β, and the levels of NLRP3, ASC, and CASPASE-1 mRNA and DNA in the colon were significantly reduced. Therefore, Xiaoyaosan may alleviate anxiety and depression by modulating the gut microbiota, correcting excessive LPS release, and inhibiting the immoderate activation of the NLRP3 inflammasome in the colon.

However, the mechanism of the effects of ERS on NLRP3 inflammasome in diabetes has not been fully understood. This review summarizes the recent researches about the effects of ERS on NLRP3 inflammasome and the related mechanism in diabetes to provide ideas for the relevant basic research in the future.

Importantly, GTD treatment effectively restored but not induced LPS/GalN-reduced the expression of AMP-activated protein kinase (AMPK) and acetyl-CoA carboxylase (ACC) phosphorylation, as well as the level of pro-autophagy proteins. Taken together, our investigation indicated that GTD played an essential role in liver protection by relieving hepatocyte apoptosis and inflammation reaction, which may be closely involved in the inhibition of NLRP3 inflammasome and NF-κB activation, regulation of apoptosis-related proteins expression, and the recovery of AMPK/ACC/autophagy.

Preclinical, Journal: Intravitreal administration of adalimumab delays retinal degeneration in rd10 mice. (Pubmed Central) - May 1, 2021 Necroptosis seems to be inhibited by the downregulation of RIPK1. Adalimumab prevented from retinal degeneration without affecting caspase -dependent mechanisms but decreasing PARP activation, microglia activation as well as NLRP3 inflammasome.
- |||||||||| Preclinical, Journal: Melatonin exerts neuroprotective effects by inhibiting neuronal pyroptosis and autophagy in STZ-induced diabetic mice. (Pubmed Central) - May 1, 2021
Furthermore, downregulation of miR-214-3p abrogated the anti-pyroptotic and anti-autophagic actions of melatonin in vitro. Our results indicate that melatonin exhibits a neuroprotective effect by inhibiting neuronal pyroptosis and excessive autophagy through modulating the miR-214-3p/caspase-1 and miR-214-3p/ATG12 axes, respectively, and it might be a potential agent for the treatment of brain damage in the setting of DM.

These data indicate that the elevated expression of gut-microbial-inflammasome components may be an important trigger for subsequent downstream activation of inflammatory and potentially cytotoxic mediators, and gastrointestinal NLRP3 may promote NLRP3 inflammasome-mediated neuroinflammation. Thus, modulation of the gut microbiota may be a potential strategy for the treatment of AD-related neurological disorders in genetically susceptible hosts.

Journal: New mechanism of neuroinflammation in Alzheimer's disease: The activation of NLRP3 inflammasome mediated by gut microbiota. (Pubmed Central) - Apr 29, 2021 In APP/PS1 mice transplanted with gut microbiota from AD patients, transplantation of healthy human gut microbiota or oral administration of minocycline was further used to improve the composition of gut microbiota...The absorption and circulation of inflammatory factors through the intestinal tract could further aggravate the inflammation in the nervous tissues and the activation of microglia. Therefore, improving the composition of gut microbiota in AD patients can further attenuate neuroinflammation, which is considered as a novel idea for AD treatment.
