Serotonergic neuron markers

Commonly used serotonergic neuron markers

Serotonergic neurons synthesize the neurotransmitter serotonin (5-HT), which is found in the gastrointestinal tract, blood platelets, and the central nervous system (CNS).

Tryptophan hydroxylase (TPH)

An enzyme involved in serotonin synthesis. There are two isoforms of tryptophan hydroxylase, TPH1 and TPH2. TPH2 is the isoform predominantly found in the brain.

Serotonin transporter (SERT)
A transmembrane protein responsible for the re-uptake of 5-HT from the synaptic cleft into the presynaptic neuron.
