Immunophilins

Immunophilins are a group of proteins inside cells that help regulate the immune system and assist in proper protein folding. They act as "chaperones," ensuring other proteins achieve their correct shape and function properly. Immunophilins also bind to certain drugs, like cyclosporine and tacrolimus, which are used to suppress immune responses after organ transplants. This makes them important in controlling immune activity and preventing organ rejection. Overall, immunophilins play a key role in maintaining cell health and immune system balance through their interactions with proteins and drugs.
