B cells produce and secrete antibodies, activating the immune system to destroy the pathogens. The main difference between T cells and B cells is that T cells can only recognize viral antigens outside the infected cells whereas B cells can recognize the surface antigens of bacteria and viruses.

Pro-B cells become pre-B cells when they express membrane m chains with surrogate light chains in the pre-B receptor. Surrogate L chains resemble actual L chains but are the same on every pre-B cell. The cell halts recombination of H chain and proliferates into a clone of B cells all producing the same m chain.

The T and B lymphocytes (T and B Cells) are involved in the acquired or antigen-specific immune response given that they are the only cells in the organism able to recognize and respond specifically to each antigenic epitope.

T cell and B cell lymphocytes work together to recognize foreign substances called antigens. As the primary agents responsible for adaptive immunity, T cells and B cells are sometimes called the “special ops” of the immune system.

A lymphocyte is a type of white blood cell in the immune system of jawed vertebrates. Lymphocytes include natural killer cells (which function in cell-mediated, cytotoxic innate immunity), T cells (for cell-mediated, cytotoxic adaptive immunity), and B cells (for humoral, antibody-driven adaptive immunity).

B cells and T cells are the white blood cells of the immune system that are responsible for adaptive immune response in an organism….T Cells vs B Cells.

T cells (also called T lymphocytes) are major components of the adaptive immune system. Their roles include directly killing infected host cells, activating other immune cells, producing cytokines and regulating the immune response.

There are two main types of lymphocytes: B cells and T cells. The B cells produce antibodies that are used to attack invading bacteria, viruses, and toxins. The T cells destroy the body’s own cells that have themselves been taken over by viruses or become cancerous.

Helper T cells activate cytotoxic T cells and B cells while cytotoxic T cells kill pathogens by phagocytosis. On the other hand, B lymphocytes produce and secrete antibodies in order to activate the immune system to destroy the antigens.

The B Cells have the ability to transform into plasmocytes and are responsible for producing antibodies (Abs). Thus, humoral immunity depends on the B Cells while cell immunity depends on the T Cells.

B lymphocytes are formed in the marrow of bone while T lymphocytes are formed in the marrow of thymus. T cells kill the infected cells while B cells produces antibodies that react with antigens.

As mentioned, the development of the heavy chain on the surface of the pro-cell transforms it into the Pre B cell. Therefore, one of the differences between the two is the fact that the pre B cell has a heavy chain on its surface.
