B Lymphocytes vs. T Lymphocytes: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Updated on October 9, 2023
B lymphocytes produce antibodies for immunity, while T lymphocytes kill infected cells and regulate immune responses.

Key Differences

B lymphocytes, or B cells, play a crucial role in the humoral immunity branch of the immune system. T lymphocytes, on the other hand, are fundamental for the cell-mediated immune response.

When B lymphocytes encounter pathogens, they differentiate into plasma cells, producing antibodies. In contrast, T lymphocytes can differentiate into various types, including cytotoxic T cells, which destroy infected cells.

B lymphocytes are primarily matured in the bone marrow. In contrast, T lymphocytes mature in the thymus, which gives them their "T" name.

The receptors on B lymphocytes recognize free-floating antigens in body fluids. T lymphocytes, however, recognize antigens presented by other cells, mainly via major histocompatibility complexes (MHC).

Both B lymphocytes and T lymphocytes have memory cells, which provide long-term immunity. However, their functions differ: memory B cells swiftly produce antibodies upon re-exposure, while memory T cells quickly launch an attack on previously encountered pathogens.
