CD33

CD33 is a protein found on the surface of certain blood cells, especially some immune cells involved in regulating immune responses. It plays a role in controlling inflammation and immune activity by transmitting signals that can inhibit or modulate the immune system's reactions. In medical research, CD33 is significant because it is involved in some blood cancers like acute myeloid leukemia (AML). Drugs targeting CD33 are being developed to help treat these cancers by directing therapies specifically to the cells expressing this protein, aiming to destroy cancerous cells while sparing healthy ones.
