Schematic diagram depicting the proposed role of proNGF/p75NTR in mediating EC death and development of acellular capillaries. Overexpression of proNGF impairs endogenous NGF/TrkA survival signaling pathway and activates p75NTR-mediated apoptotic signal. ProNGF triggers interaction of intracellular domain of p75NTR (p75ICD) and the transcriptional factor neurotrophin interacting factor (NRIF) to activate JNK apoptotic signal. Targeting p75NTR prevents the apoptotic signal and stimulates endogenous cell survival.
