are also known as B cells.
B cells are part of the immune response
. They are responsible for the humoral response
in fighting against a virus or bacteria.
B cells, types of lymphocytes, develop in the bone marrow
They fight specifically against free bacteria
, and viruses
in body fluids
(hence the humoral response
The cells involved in the defensive
response of the humoral response are the plasma cells
, memory cells
, and helper T cells which activate the B-cells
B-cells that have come in contact with an antigen
display pieces of the antigen on the surface of the cell.
The B-cell is activated
by a helper T-cell
when they bind together. The B-cell proliferates and differentiates
and grows into a clone of plasma cells and memory
The plasma cells secrete antibodies
specific to the antigen, which tag cells for destruction
