| Abstract: | Induction of the immunoglobulin production by pokeweed mitogen (PWM) and S. aureus. Cowan I has been evaluated in cultures of human peripheral blood mononuclear cells gradually depleted of adherent cells. Partial depletion cells (monitoglobulins while almost complete depletion caused decreased production. These results suggest that an optimal balance of monocytes to lymphocytes is essential in the triggering of immunoglobulin production by human mononuclear cells (MNC) in vitro and that normal monocytes, when in excess, suppress in vitro differentiation of B lymphocytes into immunoglobulin secreting cells. |
