The cell-intrinsic capacity of neurons to regenerate axons requires widespread coordination of the transcriptome, activation of multiple kinases, and reorganization of the cytoskeleton. Axonal repair is also influenced by extrinsic activating factors, such as neurotrophins. Here, we found that the neurotrophin BDNF amplifies multiple neuron-intrinsic programs to foster axonal regeneration in human iPSC-derived lower motor neurons (i Show less

The vital role of brain-derived neurotrophic factor (BDNF) in neuronal development, synaptic plasticity, and neuroprotection has been explored for decades. Therefore, the expression, processing, and signalling activities of this neurotrophin, which is reliant upon TrkB and p75NTR receptors, have been well characterised in both health and disease. This review summarises the latest findings on BDNF dysregulation in neuropathologies. Indeed, across diseases of both the central and peripheral nervous systems, BDNF signalling is frequently disrupted, contributing to neuronal dysfunction and degeneration. Consequently, through direct or indirect enhancement of its expression and/or function, BDNF has proved to be a promising therapeutic target across many neurological conditions. However, the complexity of its regulation and interaction with several different receptors underpins the need for further research to deepen our understanding of BDNF disruption in neuropathologies and to achieve its therapeutic potential.
