However, when the adaptive capacity is overcome, hemolytic erythrocyte-derived products act as signaling molecules, namely DAMPs, which promote inflammation via triggering TLR4-dependent activation of endothelial cells associated with NF-B-mediated synthesis of proinflammatory cytokines, TLR4-independent, ROS-, NADPH oxidase- and heme iron-mediated promotion of neutrophil extracellular traps (NETs) formation, TLR4-dependent activation of macrophages accompanied by secretion of tumor necrosis factor (TNF-), and MyD88/TRIF pathway-mediated TLR4-dependent microglia activation that triggers neuroinflammation [224]
Meta-analyses show SGLT2 inhibitors and GLP-1 receptor agonists lower dementia risk by 38% and 28%, respectively [250]
