Characterization of suppressor T cells in graft-versus-host reactions.

abstract：PROBLEM:NK lymphocytes play critical yet poorly defined role in implantation and during development in early pregnancy. METHODS OF STUDY:Recently, we showed that the proportion of NK that expressed CD69⁺ after incubation with K562 (CD69(stim)) cells reflected the NK population excitation potential. In the present stud...
