The role of peripheral blood T and B lymphocytes in mitogen responses during human pregnancy
Studies on the role of T and B lymphocytes of pregnant and post-partum women were performed in a pokeweed mitogen (PWM) stimulated culture system. The responses were assessed by immunofluorescent staining for intracytoplasmic immunoglobulins and solid-phase radioimmunoassay for Ig secretion into culture supernatants. As compared with non-pregnant control subjects, a slight decrease of helper T cell function and accelerated suppressor activity of T cells in pregnant and post-partum women in B cell differentiation promoted by PWM were demonstrated. Conversely, B lymphocytes in pregnant and post-partum women were hyperreactive in the presence of T lymphocytes from non-pregnant control subjects in the mitogen stimulated culture system.
