title: Surface IgM on lymphocytes from pregnant women.
abstract: Surface IgM on peripheral lymphocytes from pregnant women were passively acquired from autologous serum. These cytophilic IgM antibodies occurred as relatively large molecules, suggesting that they were in the form of complexes or aggregates. The lymphocytes involved were mainly B cells. It was postulated that the present findings could be a mechanism for the modulation of lymphocyte surface receptors by serum factors during pregnancy.
