JAK inhibitors function by blocking pivotal components ofsignaling mechanisms that are utilized by a variety of inflammatory cytokines,among them cytokines that are thought to play significant roles in themediation of disease in people who suffer from immune-mediated inflammatorydiseases.
Rheumatoid arthritis is a long-term, autoimmune diseasecharacterized by inflammation of the joints and surrounding tissues, with thepotential to affect other organs as well. In addition to pain and inflammation,the disease can also lead to joint destruction and disability. Though it canset in at any time, it appears most often in middle age, affecting women moreoften than men. Currently, approximately 1 to 2 percent of the world'spopulation suffers from rheumatoid arthritis, with roughly 2.1 million peopleafflicted in the United States.
Psoriasis is another chronic inflammatory disease, and iscaused by the overproduction of skin cells. The condition can range from mild,with only occasional flare-ups in select locations on the body, to severe,and an estimated 125 million people suffer from the condition worldwide.
