CD22

CD22 is a protein found on the surface of certain immune system cells called B cells, which produce antibodies to fight infections. It acts as a regulator, helping B cells control their activity and prevent them from overreacting. In some blood cancers like specific types of leukemia or lymphoma, B cells grow abnormally. Targeting CD22 with specialized therapies can help direct treatments precisely at these cancerous cells, reducing harm to healthy cells. Understanding CD22 is key in developing targeted treatments that improve outcomes for patients with B cell-related diseases.
