Does anyone care to answer this question: if an embryo is implanted
into the uterus of a female, why are the alloantigens not recognized by the
recipient's immune system? Does the embryo produce proteins that somehow
modulate the immune system of the woman until implantation can occur? When
the embryo continues to develop, and there is an exchange of proteins and
cells between mother and embryo, why then doesn't the mother's immune system
attack? If her immune system is somehow modulated, does this not then
diminish the effectiveness of her immune system, thus compromising it a bit?
Thank you for any response.
