TLDR p2y5, now called LPA6, is a receptor important for human hair growth.

The study identified p2y5 as a novel lysophosphatidic acid (LPA) receptor, designated LPA6, which was involved in the G12/13-Rho signaling pathways and influenced cellular morphology and cAMP accumulation. It was particularly responsive to 2-acyl-LPA and played a role in human hair growth, with genetic defects in p2y5 linked to hair growth deficiencies. The research used various assays and cell lines to confirm p2y5's function as an LPA receptor, highlighting its potential as a target for hair-related conditions. The findings extended the understanding of LPA's functional roles and receptor interactions, suggesting p2y5's involvement in specific cellular morphological changes and its impact on hair follicle development.
