Pregnancy-induced involution of the thymus can be prevented by immunizing with paternal skin grafts: a strain-dependent effect.
C57Bl female mice immunized and then mated to CBA males do not show the normal pregnancy-dependent involution of the thymus. In the reciprocal mating combination thymic involution is normal.
