It has been postulated that the progression of a pregnancy to term is, in part, the result of a relative maternal Th2 immunological state. Prostaglandins (PG) are critical mediators throughout pregnancy. Recent studies have demonstrated that one PG, PGD2, may be a mediator of a Th2 immunological state. To date, ...

An understanding of how the fetus escapes the maternal immune system may be relevant for the prevention of transplant rejection. There is evidence that the same immunosuppressive cytokines contribute to a successful pregnancy and transplant success. Transforming growth factor beta (TGF-beta) is a multifunctional cytokine that exhibits potent immunoregulatory and ...
