T lym·pho·cyte

a lymphocyte formed in the bone marrow from which it migrates to the thymic cortex to become an immunologically competent cell; T lymphocytes have long lifespans (months to years) and are responsible for cell-mediated immunity; T lymphocytes form rosettes with sheep erythrocytes and differentiate and divide in the presence of transforming agents (mitogens); T lymphocytes have characteristic T cell receptor-CD3 complexes as surface markers and may be further categorized by function, such as helper and cytotoxic.

Q. What is the best treatment for Acute Lymphocytic Leukemia? What is the best treatment for Acute Lymphocytic Leukemia? Can you please give me the hospital names and the location where the treatment could be done?

A. Combination chemotherapy. St. Jude Children's Research Hospital has reported a 5-year-survival rate of more than 90 percent for acute lymphoblastic leukemia (ALL)- on adults it's a bit lower but still a remarkable success. About the hospital- it depends where you do you live I guess…
