What are the two types of B-lymphocytes selection ?

Author: Shay 1vcc



Answer:

• Positive selection→intact receptors (IgM) • Negative selection→recognition of self antigen: B cell deletion: Alternatively, immature B cells that recognize antigens in bone marrow will die. Mature B cells: follicular B cells in lymph nodes and spleen. B-1 lymphocytes in lymphoid organs and in peritoneal cavity develop earlier.
