Research Abstract

Serotonergic neurons in the brain stem project their axons to the whole brain. The molecular mechanism of serotonergic projections had been almost unknown. We showed that single-pass transmembrane protein PcdhαC2 cell-autonomously regulates serotonergic axonal distribution, using Pcdhα mutant mice. The extracellular domain of PcdhαC2 showed homophilic interaction. Therefore distribution of serotonergic axons may be regulated by PcdhαC2 homophilic interaction
