CELLS OF THE IMMUNE RESPONSE Immune responsive cells can be divided into five groups based on i) the presence of specific surface components and ii) function: B-cells (B lymphocytes), T-cells (T lymphocytes), Accessory cells (Macrophages and other antigen-presenting cells), Killer cells (NK and K cells), and Mast cells. Some of the properties of each group are listed below . Cell group Surface components Function B-lymphocytes Surface immunoglobuli n (Ag recognition) Immunoglobuli n Fc receptor Class II Major Histocompatabi lity Complex (MHC) molecule (Ag presentation) Direct antigen recognition Differentiation into antibody- producing plasma cells Antigen presentation within Class II MHC T-lymphocytes CD3 molecule T-cell receptor (TCR, Ag recognition) Involved in both humoral and cell- mediated responses Helper T-cells (T H ) CD4 molecule Recognizes antigen presented within Class II
