Brain-derived neurotrophic factor (BDNF) is a small, diffusible protein essential for the development and function of neurons. It is synthesized by many types of tissue, including muscle. BDNF actions are mediated via binding to its receptor, tyrosine receptor kinase B (TrkB). The BDNF-TrkB complex is endocytosed into a specialized vesicle, which induces downstream signaling cascades locally in the dendrites, or, more often, is delivered to the cell soma via retrograde axonal transport, where it modulates gene expression. BDNF activation of TrkB is critical for the initiation of axonal transport, and this cellular process relies on the interaction of numerous adaptor …

Brain-derived neurotrophic factor (BDNF) is a neurotrophin required for the differentiation, growth, and survival of neurons. BDNF is synthesized in several tissue types including skeletal muscle. Neuromuscular diseases (NMDs) are characterized by the degeneration of motorneurons and/or associated skeletal muscles, and reduced BDNF is implicated in NMDs. Using Cre-Lox gene recombination technology our lab generated transgenic mice in which the BDNF gene was knocked out of skeletal muscle. We hypothesized that skeletal muscle-BDNF is required for normal retrograde transport of proteins and mitochondria along gastrocnemius-associated motorneuron axons. We first measured accumulation of the retrogradely transported phosphorylated neurofilament-H (NF-H-P) protein at …
