Abstract: | The functional capability of antigen-stimulated breast milk cells to produce an immunologic mediator was examined. Colostrum and comparison peripheral blood samples were obtained from ten women, two to four days postpartum, and supernatants from PPD-stimulated mononuclear cell cultures were assayed for the lymphokine, monocyte chemotactic factor. Five of the ten women studied had a history of a positive tuberculin skin test and one had received BCG immunization. Peripheral blood lymphocyte cultures and colostrum cell cultures from four of these six women produced monocyte chemotactic factor. These results demonstrated the functional capability of antigen-stimulated colostra! cells to produce immunologic mediators. |
