Neuroregeneration-related molecular targets

Neuroregeneration-related molecular targets encompass a broad array of proteins and signaling pathways involved in the repair, regrowth, and functional recovery of the nervous system. These targets are generally classified into two groups: those that intrinsically promote neuronal growth and those that extrinsically inhibit it within the central nervous system (CNS) environment. Key intrinsic targets include neurotrophic factors like Brain-derived neurotrophic factor (BDNF) and intracellular regulators such as PTEN and SOCS3, which modulate the mTOR and JAK/STAT pathways (Park et al., 2008, Science). Extrinsic targets include myelin-associated inhibitors like Nogo-A, Myelin-associated glycoprotein (MAG), and Chondroitin sulfate proteoglycans (CSPGs) found in the glial scar (Schwab & Strittmatter, 2014, Nature Reviews Neuroscience). In diseases such as spinal cord injury, stroke, and Amyotrophic Lateral Sclerosis (ALS), these pathways are often dysregulated, leading to permanent functional deficits. Therapeutic strategies targeting these molecules involve the use of monoclonal antibodies, small molecule inhibitors like Rho-kinase (ROCK) inhibitors, and gene therapies to stimulate axonal sprouting and synaptogenesis. Monitoring efficacy often relies on neuroimaging and fluid biomarkers like Neurofilament light chain (NfL) to assess axonal integrity (Zetterberg, 2016, Neuron).

The mechanisms of action for drugs in this category involve the antagonism of inhibitory signaling (e.g., blocking Nogo-A or Rho-associated protein kinase), the agonism of growth-promoting neurotrophic receptors such as TrkB, or the modulation of intracellular pathways like PI3K/AKT/mTOR and JAK/STAT to overcome the regenerative failure of adult central nervous system neurons (Park et al., 2008, Science; Schwab & Strittmatter, 2014, Nature Reviews Neuroscience).
