Nerve injury and regeneration

When a nerve is damaged, the body's ability to repair it depends heavily on a class of proteins called neurotrophins, which include BDNF and GDNF, molecules that regulate whether neurons survive, grow new connections, or strengthen existing ones. Researchers in this area investigate how these signaling proteins guide axon regrowth after injury, shape synaptic plasticity during recovery, and influence conditions ranging from spinal cord trauma to mood disorders like depression. A central challenge is that regeneration in the central nervous system remains far more limited than in peripheral nerves, and understanding why — and how neurotrophin pathways might be harnessed to overcome that barrier — is an active area of investigation. Open questions include how to deliver these signals precisely enough to promote recovery without triggering unwanted growth or off-target effects elsewhere in the nervous system.
