Popis: Mouse amniotic fluid has been shown to suppress T lymphocyte proliferation and suggested to be important in regulating immunity during pregnancy. In allogeneic pregnancy, cytotoxic T cells in pregnant lymphocytes against paternal transplantation antigen are impaired. We examined the effect of amniotic fluid to the alloreactive CTL responses. Although the amniotic fluid suppressed Con A or LPS stimulated lymphocyte proliferation as previously reported, the amniotic fluid taken from syngeneic C57BL/6 pregnant mice or allogeneic C57BL/6 x BALB/c pregnant mice enhanced the anti-H-2d or anti-H-2k CTL responses dose-dependently. We speculate that amniotic fluid contains not only immunosuppressive factors but also immunoenhancing factors which upregulate the allogeneic CTL responses.
