PLXDC2 Pathway

The PLXDC2 pathway is a transmembrane receptor associated with immunoregulatory functions. Immunologically, PLXDC2 activation leads to the production of IL-10 and prevention of oxidative stress. PLXDC2 intercepts the receptor for advanced glycation end-products (RAGE) signaling pathway. This leads to downstream inhibition of NF-kappa B and HIF-1-alpha signaling that is associated with TNF-alpha, IL-6, MCP1 and other cytokines. Further supporting this anti-inflammatory cascade is an inhibition of the semaphorin 4A/plexin B1 axis that regulates MAPK activation. Through proteolysis of the VEGF receptor, activation of PLXDC2 can also induce anti-angiogenic effects that can limit immune cell infiltration and defects in tissue vascularization and anti-fibrotic effects that can reduce the production of fibronectin.
