Class II MHC molecules are heterodimeric transmembrane glycoproteins that function in the presentation of Ag to CD4+ T cells. Deletion of the cytoplasmic domains of the murine class II A alpha- and A beta-chains has previously been shown to diminish

The MHC class II transactivator gene (CIITA) coordinately controls the expression of the three major human class II genes, HLA-DR, HLA-DQ, and HLA-DP. Indeed, patients with one form of MHC class II immunodeficiency disease, due to defective CIITA gen

Many tumor cells that have been transfected with genes encoding B7 costimulatory molecules become effective cellular vaccines against wild-type tumor. The improved immunity is dependent on newly induced tumor-specific CD8+ and/or CD4+ T cells and pre

Immune responses to pathogens often lead to the generation of polarized T helper subsets designated Th1 and Th2. Th1 cells, characterized by the production of IL-2 and IFN-gamma, stimulate cellular immune responses important for protection against in

The ability of the staphylococcal enterotoxins to stimulate T cells has been thought to depend on their association with class II MHC products. Here, we demonstrate that a subgroup of staphylococcal enterotoxins, which includes staphylococcal enterot

Recent evidence suggests that I-E+ thymic epithelium, especially medullary epithelium, can induce partial deletion of superantigen-reactive T cells expressing TcR V beta 5, V beta 11, and V beta 17. To seek further information on this issue, we const

We have examined the transcriptional regulation of the Th1-specific IL-2 gene and the Th2-specific IL-4 gene by transient transfection of promoter-chloramphenicol acetyl transferase (CAT) constructs into T cell clones and by electrophoretic mobility

MHC class I and class II molecules are essential for intrathymic maturation of a normal repertoire of alpha beta T cells. The development of gamma delta T cells may similarly require exposure to conventional MHC or MHC-like molecules for appropriate

Transforming growth factor beta 1 (TGF-beta 1) is a pleiotropic cytokine that decreases the expression of class II MHC Ag in the melanoma cell line Hs294T(c). To investigate the mechanism of this repression, we have examined the effect of TGF-beta 1

The class II genes of the major histocompatibility complex are a family of genes whose expression is regulated developmentally in cells of the B lineage and by IFN-gamma in many other cell types. Using the approach of in vivo footprinting, which allo
