What is AB cell?

What is AB cell?

B cells are a type of lymphocyte that are responsible for the humoral immunity component of the adaptive immune system. These white blood cells produce antibodies, which play a key part in immunity. Lymphocytes account for about 25% of white blood cells, and B cells represent approximately 10% of total lymphocytes.

How does AB cell produce antibodies?

Antibodies are produced by specialized white blood cells called B lymphocytes (or B cells). When an antigen binds to the B-cell surface, it stimulates the B cell to divide and mature into a group of identical cells called a clone. Antibodies attack antigens by binding to them.

What lymphocytes make antibodies?

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.

This is different from T-cells, which can only connect to virus antigens on the outside of infected cells. Your body has up to 10 billion different B-cells.
