medications that suppress immune response by blocking calcineurin activity
Calcineurin inhibitors (CNIs) are a class of medications that suppress the immune system by blocking the activity of calcineurin, a protein involved in activating T-cells. They are commonly used to prevent organ transplant rejection and to treat autoimmune diseases. In dermatology, CNIs like tacrolimus and pimecrolimus are used topically to manage conditions such as atopic dermatitis and certain types of alopecia, as they help reduce inflammation and immune response in the skin.
