The BCR signalling pathway is a pathway that plays a vital role in the development and all other functions of B-cells, which means it is vital for the immune response. The BCR, also known as the B-cell receptor, is usually found on the outer membrane of B-cells. B-cells grab antigens from immune synapses, through a number of processes including cell spreading and receptor transport. After these have been performed, endocytosis and antigen-presentation occur. B-cells manipulate the dynamic of BCR-antigen bonds. They group and spread the antigen, increasing the relation with BCR, which creates sensitivity. The two main functions of the BCR pathway is to signal transduction, and the second is to prepare the antigen for processing by the helper T cells. Any defects in this pathway may lead to the patient being immunodeficient, or having B-cell malignancy.
