Lymphocyte Function
Main function
of lymphocytes:
Regulation
of immune function
1. Antigen fragments carried to lymph
nodes
3. Follicle dendritic cells in cortex
process antigen
2. Macrophages in medullary area
process antigen
4. IL-1 from macrophage:
Activates CD8+ cells
to destroy cells
Process of
lymphocyte in immune response:
Activates B-cells to
produce antibodies
5. Ag + MHC-I required for CD8+
activation
6. Ag + MHC-II required for CD4+
activation
7. B-cells don’t need CD4+
stimulation if antigen is a polysaccharide
