CB2R activation ameliorates late adolescent chronic alcohol exposure-induced anxiety-like behaviors during withdrawal by preventing morphological changes and suppressing NLRP3 inflammasome activation in the microglia of the prefrontal cortex in mice

85 views | Feb 25 2023

Chronic alcohol exposure in late adolescence increases anxiety-like behaviors by activating microglia in the prefrontal cortex, which can be prevented by activating the cannabinoid type 2 receptor through CB2R agonist treatment. [Read the Full Post]

Dapagliflozin protects against dilated cardiomyopathy progression by targeting NLRP3 inflammasome activation

86 views | Feb 25 2023

Dapagliflozin, a SGLT2 inhibitor, improves cardiac function in doxorubicin-induced dilated cardiomyopathy by suppressing the activation of the NLRP3 inflammasome through decreased p38-dependent TLR4 expression. [Read the Full Post]

Metabolomic profiling in kidney cells treated with a sodium glucose-cotransporter 2 inhibitor

58 views | Feb 25 2023

Our study found that high glucose conditions in kidney cells altered the metabolomic profile, and treatment with SGLT2 inhibitor dapagliflozin led to significant changes in the levels of metabolites such as asparagine, PC ae C34:1 and PC ae C36:2 in tubular epithelial cells, and PC aa C32:0 in podocytes, which affected multiple metabolic pathways.
