CD4 is a molecule expressed on the surface of T lymphocytes which recognize foreign protein antigens in the context of class II major histocompatibility complex (MHC) molecules. Recognition of antigen:class II MHC complexes by CD4+ T cells can be inhibited by anti-CD4 (ref. 3). Nevertheless, specific recognition of the antigen:Ia complex is clearly a(More)
A murine cloned Th cell line specific for the antigen conalbumin in the context of self I-A molecules can be activated by low concentrations of soluble antireceptor mAb. By using an antireceptor mAb to shared antigenic determinants on T cell receptors, we have shown that the ability to be activated by soluble antireceptor mAb is an unusual, although not(More)
The cutaneous graft-versus-host disease (GVHD) lesions induced by intradermal injection of cloned autoreactive T cells have been shown to subside rapidly and the epidermis returns to normal 2 wk after injection. Those mice that had spontaneously recovered from the cutaneous GVHD became resistant to subsequent attempts to induce the cutaneous GVHD by the T(More)
