Soluble alpha 1 acid-glycoprotein is considered an "acute phase protein" with an inhibitory effect on lymphocyte activity; it has recently been shown that a lymphocyte modulatory variant of alpha 1 acid-glycoprotein has a positive role on T cell activation. It is not clear whether the presence of this glycoprotein on lymphocyte membranes is due to an endogenous production or to a passive uptake of soluble alpha 1 acid-glycoprotein by its carbohydrate moiety. Our data show an increase of membrane alpha 1 acid-glycoprotein both in peripheral blood lymphocyte and T-enriched lymphocytes after phytohemagglutinin stimulation. Peripheral blood lymphocyte enzymatic treatment by neuraminidase does not affect alpha 1 acid-glycoprotein expression while pronase digestion induces a strong decrease of alpha 1 acid-glycoprotein positive lymphocytes and a resynthesis after phytohemagglutinin stimulation. Furthermore, the presence of alpha 1 acid-glycoprotein was prevalently, found on helper/inducer lymphocytes. These data support the hypothesis of a synthesis of alpha 1 acid-glycoprotein by T lymphocytes during their activation process.
