lymphocytes
White blood defenders
Lymphocytes are white blood cells central to the immune system's response to infection and disease.
The main types are T cells, which attack infected cells directly, and B cells, which produce antibodies.
Lymphocyte counts in blood tests help diagnose infections, immune disorders, and cancers like leukemia and lymphoma: Her lymphocyte count was dangerously low after chemotherapy.
