Abstract

In addition to its role as a neurotransmitter, the indolamine serotonin [5-hydroxytryptamine (5-HT)] also acts as a signaling molecule for 5-HT neuron growth in the developing brain. Detected in the first trimester of the human central nervous system, 5-HT acts as a trophic factor-a regulator of neuronal growth, differentiation, migration, and survival. The trophic role of 5-HT occurs long before synapse formation and the need for 5-HT to perform as a neurotransmitter. The trophic role of 5-HT continues throughout prenatal and early postnatal development. Disruption, even transient deviations, of the 5-HT system during development, can lead to permanent alterations in brain function and behavior. One neurodevelopmental condition with growing evidence of 5-HT involvement is autism spectrum disorder.
