SCAR

Retinoic acid receptor (RAR) β signalling is involved in central nervous system (CNS) regeneration.RARβ is a neuronal transcription factor that regulates numerous pathways in CNS regeneration; these include, axonal outgrowth, synaptogenesis, modulation of the glial scar and axonal pathfinding.KCL‐286 is a preclinical RARβ agonist developed to treat CNS injuries.
