B cells, also known as B lymphocytes, are a type of white blood cell of the small lymphocyte In mammals, B cells mature in the bone marrow, which is at the core of most bones. In birds, B cells mature in the bursa of Fabricius, a lymphoid.
The T Cell: T-cells mature in the thymus gland or in the lymph nodes. Since the thymus is only % functional in the adult, the lymph nodes take on greater.
Rather, eventual B cells continue to mature in the bone marrow. The first step of B cell maturation is an assessment of the functionality of their antigen-binding.
T3 B cells do not give rise to mature B cells, but instead represent a subset of anergic B cells which have been selected away from the B cell developmental.
