Mechanisms Controlling the Expression and Secretion of BDNF

Biomolecules. 2023 May 2;13(5):789. doi: 10.3390/biom13050789.

Abstract

Brain-derived nerve factor (BDNF), through TrkB receptor activation, is an important modulator for many different physiological and pathological functions in the nervous system. Among them, BDNF plays a crucial role in the development and correct maintenance of brain circuits and synaptic plasticity as well as in neurodegenerative diseases. The proper functioning of the central nervous system depends on the available BDNF concentrations, which are tightly regulated at transcriptional and translational levels but also by its regulated secretion. In this review we summarize the new advances regarding the molecular players involved in BDNF release. In addition, we will address how changes of their levels or function in these proteins have a great impact in those functions modulated by BDNF under physiological and pathological conditions.

Keywords: BDNF; Ca2+; expression; nerve cells; neurotrophin release; neurotrophins; proBDNF; secretion; synaptic activity.
