title: Rat pregnancy induces two suppressor cell activities.
abstract: Pregnancy in rat is able to stimulate two suppressor cell activities. One is specific to the paternal histocompatibility antigens and it resides in the T-lymphocyte population. The second is nonspecific and is of non-T nature. The use of various methods for pseudopregnancy and deciduoma installation has allowed the demonstration of two inducing circuits: (a) the presence of fertilized ova in the female genital tract and (b) the progestation hormonal status.
