TRPC6
Transient receptor potential cation channel, subfamily C, member 6, also known as TRPC6, is a human gene encoding a protein of the same name. TRPC6 is a transient receptor potential channel of the classical TRPC subfamily. It has been associated with depression and anxiety (see below), as well as with focal segmental glomerulosclerosis (FSGS).[5]
Ligands
Two of the primary active constituents responsible for the antidepressant and anxiolytic benefits of Hypericum perforatum, also known as St. John's Wort, are hyperforin and adhyperforin.[9][10] These compounds are inhibitors of the reuptake of serotonin, norepinephrine, dopamine, γ-aminobutyric acid, and glutamate, and they are reported to exert these effects by binding to and activating TRPC6.[10][11] Recent results with hyperforin have cast doubt on these findings as similar currents are seen upon Hyperforin treatment regardless of the presence of TRPC6.[12]
