BACKGROUND: Janus kinase (JAK) inhibitors are emerging as a promising new treatment modality for many inflammatory conditions. Two new studies researching a class of drugs called JAK inhibitors have shown that oral treatment results in significant hair regrowth in patients with alopecia areata, an autoimmune condition that causes non-scarring patches of localized hair loss. One such study was presented this month at the European Academy of Dermatology and Venereology Congress in Paris. The aim of this review article is to present updated data summary on the tofacitinib in the field of dermatology. The STATS, of which there are seven, bind to the phosphorylated cytokine-receptor complex and, after phosphorylation by a JAK, they translocate to the nucleus, bind DNA and activate target gene transcription (see Figure 1). 5 points for JAK3 and TYK2/JAK1, respectively) as The first JAK inhibitor to reach clinical trials was tofacitinib.

JAK inhibitors in dermatology: The promise of a new drug To date, JAK inhibitors have shown efficacy in the treatment of dermatologic conditions such as AD, alopecia areata (AA), psoriasis, and vitiligo, among others. Proteins in our cells need ways to carry messages, but since they don’t have iPhones, our cells often send messages via proteins that pass phosphates to one another like a message being carried from person to person. Harel et al. The Janus kinase (JAK) and signal transducer and activator of transcription (STAT) pathway is a ubiquitous intracellular signaling network. These skin-targeted, “soft” JAK inhibitors are designed to be active in the skin but rapidly metabolized in the circulation. Janus kinase inhibitors, also known as JAK inhibitors or jakinibs, are a type of medication that functions by inhibiting the activity of one or more of the Janus kinase family of enzymes (JAK1, JAK2, JAK3, TYK2), thereby interfering with the JAK-STAT signaling pathway. Pharmacologic inhibition of JAK-STAT signaling promotes hair growth. Therefore, some JAK inhibitors are more selective, (eg, JAK1 inhibitor or JAK3 inhibitor), and others have broader activity, (eg, JAK1/3 inhibitor). JAK inhibitors like Xeljanz have been shown to grow back hair and pigment, but a safer more practical approach would be to develop these drugs in a topical form.

Treating Alopecia Areata, Vitiligo and Atopic Dermatitis: JAK Inhibitors, Something New for Dermatology Janus kinase (JAK) inhibitors are small molecule drugs that can inhibit cytokine-mediated cell signaling in target cells by inhibiting JAK-1, JAK-2, and/or JAK-3 subtypes. Indeed, JAK inhibitors are demonstrating benefit across multiple dermatologic diseases and constitute a promising frontier for dermatologic therapy overall. JAK INHIBITORS IN THE TREATMENT ALGORITHM OF RHEUMATOID ARTHRITIS.
