Cellular immune response following thermal injury in human patients.
Cellular immune response was studied longitudinally for a period of 1 month in a group of 51 patients sustaining burns between 20 and 55 per cent of their body surface area. The results indicated lymphocytopenia and significant depression in the total T cells in all the patients. T cells showed a significant rise in their levels in those patients who showed clinical improvement. Further, the loss of expression of 'E' receptor correlated with the lowering of the protein-synthesizing capacity of the mononuclear cells. The functional integrity of the lymphocytes also showed an inability to recognize and stimulate normal alloantigens in an MLR reaction. Investigation of the mechanisms responsible for immunosuppression revealed the generation of T suppressor activity.
