WebB-Cell receptors are protein molecules attached to the B-Cell surface. The principal element of a B cell is to create antibodies against the foreign organisms that enter our body. These are known as B lymphocytes or simply the B-Cells. These cells form an essential part of creating immunity. WebBoth types of T-cell receptor differ from the membrane-bound immunoglobulin that serves as the B-cell receptor: a T-cell receptor has only one antigen-binding site , whereas a B-cell receptor has two, and T-cell receptors are never secreted, whereas immunoglobulin can be secreted as antibody.
