5-hydroxytryptamine receptor 1B also known as the 5-HT1B receptor is a protein that in humans is encoded by the HTR1B gene.[1][2] The 5-HT1B receptor is a 5-HT receptor subtype.[3]

Tissue distribution and function

5-HT1B receptors are widely distributed throughout the CNS with the highest concentrations found in the frontal cortex, basal ganglia, striatum, and the hippocampus.[4] The function of the 5-HT1B receptor differs depending upon its location. In the frontal cortex, it is believed to act as a postsynaptic receptor inhibiting the release of dopamine. In the basal ganglia and the striatum, evidence suggests 5-HT signaling acts on an autoreceptor, inhibiting the release of serotonin[5] and decreasing glutamatergic transmission by reducing miniature excitatory postsynaptic potential (mEPSP) frequency,[6] respectively. In the hippocampus, a recent study has demonstrated that activation of postsynaptic 5-HT1B heteroreceptors produces a facilitation in excitatory synaptic transmission which is altered in depression.[7] When the expression of 5-HT1B in human cortex was traced throughout life, significant changes during adolescence were observed, in a way that is strongly correlated with the expression of 5-HT1E.[8]

Outside the brain, 5-HT1B receptor activation also has vascular effects, such as pulmonary vasoconstriction. Furthermore, blocking 5-HT1B receptor signalling increases the number of osteoblasts, bone mass, and the bone formation rate.[9]

Knockout mice lacking the 5-HT1B gene have shown an increase in aggression and a higher preference for alcohol.[10] Under basal conditions, knockout mice present with a "normal" phenotype and exhibit a sucrose preference (lack of sucrose preference is considered a measure of anhedonia). However, after undergoing chronic unpredictable stress treatment to induce a "depression-like" phenotype these animals do not benefit from administration of selective serotonin reuptake inhibitor (SSRIs).[7]



Partial agonists

Antagonists and inverse agonists


In humans the protein is coded by the gene HTR1B.

A genetic variant in the promotor region, A-161T, has been examined with respect to personality traits and showed no major effect.[15]
