One such molecule is the microglial cell surface receptor TREM2 (triggering receptor expressed on myeloid cells 2), which recognizes misfolded proteins like amyloid and activates microglia to clear them
This is demonstrated by comparing the effects of DPP-4 inhibitors vs
Excessive stress can lead to increased glutamate release and overactivation of NMDAR, resulting in calcium influx and subsequent activation of intracellular signaling pathways that cause neuronal atrophy and death, ultimately leading to mood disorders and depression-like symptoms ( Lycium barbarum polysaccharide (LBP, 25, 50, and 100 mg/kg) to rats for three consecutive weeks intragastrically was found to effectively inhibit the excessive activation of NR2B in the prefrontal cortex of rats, reduce the expression of calmodulin kinase II (CaMKII), a crucial downstream signaling molecule of NMDAR, and alleviate depressive-like behaviors in rats with PTSD ( The natural plant polysaccharides have the ability to modulate neurotransmitters in the brain
