Difference between B-Cells and T-Cells – Comparison Table

B Lymphocytes vs T Lymphocytes

B-Cells vs T-Cells
(Similarities and Differences between B-Lymphocytes and T-Lymphocytes)

Lymphocytes are the key cells of the immune system and they are responsible for the adaptive immune response of an organism. They are also responsible many of the immunological characteristics such as specificity, diversity, memory and self/non-self recognition. Lymphocytes constitute about 20 – 40% of the body’s White blood cells and 99% of the cells of the lymph. Lymphocytes are broadly classified into THREE populations based on their function, lifespan, cell surface components and most importantly their place of maturation. They are B-Lymphocytes (B-Cells), T-Lymphocytes (T-Cells) and Natural Killer Cells (NK Cells).

B-Lymphocytes (B-Cells): They mature in the bone marrow or bursa (in birds). B-cells possess membrane bound immunoglobulins which acts as the receptors for the antigens. They are involved in the humoral (antibody mediated) immune responses.

T-Lymphocytes (T-Cells): They mature in the thymus, hence the name. T-cells possess receptors for antigens on their surface but it is structurally different from immunoglobulins. They are involved in Cell-mediated immune responses.

The present post discusses the Similarities and Differences between B-Lymphocytes (B-Cells) and T-Lymphocytes (T-Cells) with a Comparison Table.
