Oclacitinib em processos dermatológicos da medicina veterinária – revisão de literatura

Abstract

The Janus kinase signal transducer and activator of transcription (JAK-STAT) pathway is utilized by cytokines, including interleukins (ILs), interferons (IFNs), and other molecules to transmit signal from the cell membrane to the nucleus. Inflammatory cytokines rely on JAK-STAT signaling, which is indispensable for immune and hematopoietic function. JAK inhibitors were developed for the treatment of a variety of inflammatory, immune-mediated, and hematopoietic disorders in humans. Evidence suggests that JAK inhibitors are efficacious in the treatment of atopic dermatitis, alopecia areata, psoriasis, and vitiligo. The first generation of JAK inhibitors included tofacitinib, ruxolitinib, baricitinib, and oclacitinib. Oclacitinib is used exclusively in veterinary medicine, and recent studies have shown that this drug has a rapid effect on pruritus and lesion reduction in dogs with atopic dermatitis. This article aimed to review this new class of drugs, focusing on the use of oclacitinib in veterinary medicine.
