Tph2 deficiency shapes neurodevelopmental behavioral trajectories through interactions with the maternal environment, sex, and the gut microbiome
Serotonin (5-HT) is critical for neurodevelopment, influencing brain maturation, emotional regulation, and social behavior. Tryptophan hydroxylase 2 (TPH2), the rate-limiting enzyme for central 5-HT synthesis, causes lifelong 5-HT depletion when disrupted. While early-life 5-HT perturbations are linked to neuropsyc...
