April 2019 in “Journal of Investigative Dermatology” This study reported that gain-of-function mutations in TRPV3 lead to hair loss in mice by disrupting inner root sheath keratinocyte differentiation, ultimately causing follicular keratinocyte stem cell exhaustion and permanent follicle disruption.
This study utilized a pigmented human epidermal equivalent model to incorporate melanocytes into the epidermis and found enhanced differentiation potential compared to conventional in vitro systems, reflecting in vivo cellular trajectories and highlighting melanocyte-to-keratinocyte communication pathways.
