The cell-mediated immunity inside the human body is carried out by

  • T-lymphocytes

  • B-lymphocytes

  • thrombocytes

  • erythrocytes

Solution

A.

T-lymphocytes

T- lymphocyte receptors can recognise only antigen that bound to cell membrane proteins. These lymphocytes mediate CMI (cell mediated immunity).

B-lymphocytes are the major effector molecules of humoral immunity. Erythrocytes are red blood cells. Thrombocytes or platelets secrete factors that are involved in vascular repair.
