This system modulates the allergic response by creating immune tolerance to antigens.

It is one method of immune tolerance.

But they also hoped the transplants would induce a state of immune tolerance in the patient, a condition known as mixed chimerism.

It may thus be regarded as insufficient immune tolerance in pregnancy.

The antibodies may exert a physical effect on the T cells, changing them in subtle ways that induce immune tolerance, he said.

The results look promising, he said, but those experiments used only one antibody and researchers have not looked to see if they achieved immune tolerance.

They have found that this strategy, called immune tolerance, reduces the effects of the disease.

He worked on graft rejection and the discovery of acquired immune tolerance.

This phenomenon is commonly known as "acquired immune tolerance".
