How does Tremfya (guselkumab) work?
Psoriasis is a chronic autoimmune condition, characterized by raised areas of inflamed skin. Psoriatic arthritis is a type of chronic inflammatory arthritis that presents with painful inflammation of the joints and surrounding connective tissue.[2]
The cytokine interleukin 23 (IL-23) is found to be very important in the development of psoriasis. Cytokines play a role in signaling in a cell. IL-23 signaling can increase the risk of developing inflammation in the body, which causes the onset of psoriasis.[2]
Guselkumab is a human monoclonal antibody, a type of protein, that binds to the IL-23. Hereby, it will block its action, and thereby slow down inflammation in patients.[1]
