Glossary Janus Kinase Inhibitors

medications that block enzymes involved in immune response signaling

Janus Kinase Inhibitors, often referred to as JAK inhibitors, are a class of medications that block the activity of Janus kinases, which are enzymes involved in the signaling pathways that regulate immune responses and inflammation. By inhibiting these enzymes, JAK inhibitors can help manage conditions like rheumatoid arthritis, psoriasis, and certain types of alopecia, where the immune system mistakenly attacks the body's own tissues.
