Antigen receptor Definition

  • In adaptive immunity, recognition occurs when a B cell or T cell binds to an antigen, such as a bacterial or viral protein, via a protein called an antigen receptor.

Antigen receptor Explanation

An antigen receptor is basically an antibody protein that is not secreted but is anchored to the B-cell membrane. An antigen receptor recognizes the antigen particle and initiates a specific immune response against. Each antibody is specifically produced by the immune system to match an antigen after cells in the immune system come into contact with it; this allows a precise identification or matching of the antigen and the initiation of a tailored response.All antigen receptors found on a particular B cell are identical, but receptors located on other B cells differ
