Abstract
Human peripheral blood mononuclear cells showed increased synthesis and secretion of protein in response to stimulation by mitogens. Protein secretion in response to concanavalin A (Con A) correlated with cellular proliferation and originated from the proliferating cells. Selective depletion of either B lymphocytes or monocytes did not lead to a reduction in the total protein secreted, suggesting that the T lymphocyte was the cell contributing most of the synthetic activity. It is concluded that the measurement of newly synthesized and secreted protein by Con A activated mononuclear cells is a measurement of the T-lymphocyte response.
