NTRK2 and central nervous system disorder: A novel tropomyosin receptor kinase B (TrkB) agonist was identified using T7 phage biopanning, reported by Ohnishi et al.[53] TrkB is a well‐known brain‐derived neurotrophic factor (BDNF) receptor, which shows the ability to regulate the survival, maturation, and development of neurons, making it a good target for the central nervous system diseases treatment.
