Immune Reconstitution

Immune reconstitution refers to the process where the immune system recovers and regains its ability to fight infections after it has been weakened or suppressed, such as during treatments like chemotherapy, HIV therapy, or bone marrow transplants. During this recovery, the immune cells — especially lymphocytes — increase in number and function, restoring the body’s defenses against illnesses. This process varies in speed depending on individual health and treatment type. Essentially, immune reconstitution is the body's way of rebuilding its immune defenses to protect against future infections and ensure overall immune health.
