Overview of Interleukin Inhibitors
Interleukins are cytokines that play a central role in immune cell communication and inflammatory responses. Dysregulation of interleukin signaling is strongly associated with chronic inflammatory and autoimmune diseases. Interleukin inhibitors work by selectively blocking these pathways, thereby reducing inflammation and disease progression.
Common interleukin targets include:
-
IL-1 inhibitors – used in autoinflammatory disorders
-
IL-6 inhibitors – widely applied in rheumatoid arthritis and cytokine release syndrome
-
IL-17 inhibitors – key therapies for psoriasis and psoriatic arthritis
-
IL-23 inhibitors – effective in inflammatory bowel disease and dermatological conditions
