Immune-modulatory protein targets

Immune-modulatory protein targets represent a broad and diverse class of molecules that regulate the activity, intensity, and duration of immune responses. These targets include cell surface receptors such as immune checkpoints (e.g., PD-1, CTLA-4), secreted signaling molecules like cytokines (e.g., TNF-alpha, IL-6), and intracellular enzymes (e.g., JAK kinases). Drugs designed to interact with these proteins are used to either enhance the immune response, as seen in cancer immunotherapy, or to suppress it, as in the treatment of autoimmune diseases and the prevention of organ transplant rejection. The therapeutic modulation of these targets has revolutionized the management of numerous conditions, including melanoma, rheumatoid arthritis, and inflammatory bowel disease. However, because these proteins are central to immune homeostasis, their pharmacological manipulation can lead to significant safety concerns, such as immune-related adverse events or a heightened susceptibility to infections.
