PG - 2510-3 AB - We found that brain-derived neurotrophic factor (BDNF)-induced phosphorylation of mitogen-activated protein kinase (MAPK) and Akt in cerebellar granule neurons was specifically potentiated by LPC. LPC also augmented the BDNF-induced phosphorylation of TrkB, the receptor for BDNF. In TrkB-transfected CHO-K1 cells, LPC potentiated BDNF-induced MAPK phosphorylation. These results suggest that LPC plays a role in BDNF-TrkB signaling by regulating the activation of TrkB. FAU - Wuhanqimuge AU - Wuhanqimuge AD - Department of Biotechnology, The University of Tokyo.
