[The effect of Mycoplasma arthritidis superantigen on immunogenesis in transplacental infection].
The immune responsiveness of the progeny of BALB/c mice, responsive to M. arthritidis superantigen (MAS), and C57BL/6 mice, nonresponsive to MAS, infected with M. arthritidis during the second half of pregnancy was studied. The investigation revealed that in responsive animals the proliferative response of spleen cells to MAS was suppressed with the level of response to concanavalin A remaining unchanged. The spleen cells of the test mice reacted to syngenic intact cells as to xenogenic ones and suppressed reaction to MAS and the production of interleukin 1 in the culture of spleen cells taken from the intact syngenic animals. The data obtained in this study suggest that after the infection of pregnant BALB/c mice with M. arthritidis immune tolerance to MAS developed in their progeny, which was accompanied by the induction of suppressor cells inhibiting the production of interleukin 1.
