Question

How do B cells recognize antigens?

Answer 1

B cells:

1. On the surface of B-cells are B-cell Receptors, which can recognize a million distinct types of antigens.
2. When it comes into touch with an antigen, however, it transforms into memory and plasma cells, which have only one type of receptor, antigenic specificity.
3. The form of the antigens on the surfaces of infectious particles helps B lymphocytes recognize them.
4. Antibodies are produced by cells that descend from a single B cell, and they remember the antigen and invader that caused them to form.
5. The B-cell receptor's principal function is to recognize and bind antigen via the V regions on the cell's surface.
