Some more points about agranulocytes

Dear student,

agranulocytes contain lymphocytes and monocytes. Monocytes further differentiate into macrophages ( phagocytic ) cells in the tissues and lymphocytes are the main cells that provide adaptive/humoral immunity. Lymphocytes contain following cell types :

1. Natural killer cells : kill any injured / infected cell which will be phagocytosed by phagocytic cells.
2. B cells : produce antibodies that will bind with antigen to initiate other effective mechanisms to eliminate the antigen from system.
3. T cells are further of two types:

•         T helper cells : recognise the antigen (extracellular) and guide B cells to produce antibodies          
•          T cytotoxic cells or killer cell and it kills the infected and cancerous cells.

Regards.
