The murine F$ sb1$ hybrid model of graft-versus-host (GVH) disease was used to investigate the nature of GVH-induced T cell immunodeficiency. Chronic GVH reactions were induced in BAF$ sb1$ mice by the i.v. injection of 50 $ times$ 10$ sp6$ parental A strain lymphoid cells. At various days (43-139) after GVH induction the thymi and spleens were excised and used for in vitro functional studies. In addition, both lymphoid and non-lymphoid organs were evaluated histologically. Interleukin 1 (IL-1) and 2 (IL-2) were used as probes to assess the functional status of the peanut agglutinin positive (PNA$ sp-$) and peanut agglutinin negative (PNA$ sp+$) subpopulations. The results obtained strongly suggest that GVH-induced T cell immunodeficiency is due in part to a decreased responsiveness to IL-1 and IL-2, and to a marked deficiency in IL-2 production.
