5-hydroxytryptamine receptor 1B also known as the 5-HT1B receptor is a protein that in humans is encoded by the HTR1B gene.[5][6] The 5-HT1B receptor is a 5-HT receptor subtype.[7]
Tissue distribution and function
5-HT1B receptors are widely distributed throughout the
The function of the 5-HT1B receptor differs depending upon its location. In the frontal cortex, it is believed to act as a terminal 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[9] and decreasing glutamatergic transmission by reducing miniature excitatory postsynaptic potential (mEPSP) frequency,[10] 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.[11] 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.[12]Outside of the CNS, the 5-HT1B receptor is also expressed on the endothelium of blood vessels, particularly in the meninges.[13] Activation of these receptors results in vasoconstriction. The high distribution of vasoconstrictive 5-HT1B and 5-HT1D receptors around the brain makes them a valuable drug target for the treatment of migraines.[13]
Blocking 5-HT1B receptor signalling also increases the number of osteoblasts, bone mass, and the bone formation rate.[14]
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).[11][failed verification]
