investigational drug targeting enzymes involved in autoimmune hair loss
Ritlecitinib is an investigational drug that targets specific enzymes known as Janus kinases (JAKs) and TEC family kinases, which are involved in the immune response. It is being studied for its potential to treat autoimmune conditions like alopecia areata, where the immune system mistakenly attacks hair follicles, leading to hair loss.
