Clinical use showed visible improvement in skin brightness and reduction in surface pigmentation
SCFAs activate GPCR41/43 to reduce hepatic cholesterol synthesis, inhibit NF-B-mediated inflammation, and enhance endothelial nitric oxide (NO) production ( / mice, SCFAs reduce aortic plaque area by 3040% ( 3.2 Inflammatory activation: LPS and cytokine cascades Gut barrier disruption (reduced occludin, ZO-1 expression) allows LPS translocation, activating TLR4/NF-B signaling in macrophages and endothelial cells ( 3.3 Vascular dysfunction: endothelial injury and oxidative stress Dysbiosis-derived metabolites (TMAO, LPS) and reduced SCFAs impair endothelial function by decreasing NO bioavailability and increasing reactive oxygen species (ROS) ( 4 Probiotics in atherosclerosis: mechanisms of action Probiotics exert anti-atherosclerotic effects through strain-specific modulation of gut microbiota, metabolic homeostasis, inflammation, and vascular function ( Table 1 )

Extended Data Table 1) were randomly divided into two groups at a ratio of 1:1, where one group received SCAN stimulation (SCAN group, n = 18) and the other M1 effector-specific stimulation (effector group, n = 18), over a span of 14 consecutive days

The underlying mechanism for hyperhomocysteinemia-induced NLRP3 inflammasome activation is through the generation of ROS (Wang et al
