Do plasma glycoproteins induce lymphocyte hyporesponsiveness and insulin resistance?
Depression of lymphocyte transformation and an increase in insulin resistance are common to pregnancy, oral contraceptive use, widespread malignancy, infection, and tissue destruction. We suggest that these abnormalities are caused by a rise in the plasma-glycoprotein level which is also common to these clinical states. There is evidence that glycoproteins can inhibit cell division, lymphocyte transformation, and the action of hormones on target cells. Because of the increase in plasma glycoprotein the cells in many organs and their hormone receptors may have a thicker coating of glycoproteins which blunts their response to variuos stimuli.
