This part of the immune response is perpetuated by antibodies which are produced by activated B cells.

Antibodies have three ways of attacking and eliminating an invading pathogen

B Cell Activation:

           B cell act

The B cell is activated by interaction with a helper T cell and differentiates in to plasma cells that secrete antibody specific to the antigen presented by the T cell. 

This process requires two seperate signals to occur at the same time:

Signal 1 – B Cell receptor crosslinking by the antigen itself

Signal 2 –
