Intracellular 5-hydroxytryptamine receptors (5-HT6R) signaling was found to be linked to RhoA GTPase activation and was involved in the maturation of osteoclasts. This signaling pathway also showed enhanced bone destruction after lipopolysaccharide (LPS) administration in mice.

Results suggest that degeneration of the nigrostriatal pathway causes the decreased dopamine levels in the limbic and limbic related brain regions and the enhanced sensitivity of the 5-HT6 receptor on the glutamate and GABA neurons in the basolateral amygdala, which appear to be an etiologic and pathophysiological factor for anxiety in Parkinson's disease.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
