Altered peptide ligands derived from T cell-reactive self antigens have been shown to be protective therapeutic agents in animal models of autoimmunity. In this study we identified several altered peptide ligands derived from the type 1 diabetes-asso

Human CD4 T cell responses to an epitope of hGAD65 (GAD = glutamic acid decarboxylase), residues 555-567, are modulated by interaction with an altered peptide ligand containing modifications at TCR contact residues. Using different HLA-DR4 molecules

Complex protein antigens contain multiple potential T cell recognition epitopes, which are generated through a processing pathway involving partial antigen degradation via proteases, binding to MHC molecules, and display on the APC surface, followed

TCR engagement of peptide-MHC class II ligands involves specific contacts between the TCR and residues on both the MHC and peptide molecules. We have used molecular modeling and assays of peptide binding and T cell function to characterize these inte

Immune recognition of foreign HLA molecules is initiated by T cell recognition mediated by alloreactive T cell receptor (TCR) molecules. We analyzed the diversity of TCR expression in the clinical setting of allorecognition in a patient with acute gr

Bacterial superantigens have two immunologically important features. They bind MHC class II molecules and stimulate T cells bearing certain V beta TCR phenotypes. Superantigens such as SEA, SEB, and TSST bind to each of the three HLA class II isotype

HLA-DR4 has been shown to be associated with risk for developing rheumatoid arthritis (RA) in multiple populations and racial groups. The allelic variants of DR4 share the DR4 serologic specificity but differ by 1 to 3 amino acids in the third hyperv

Crosslinking HLA-DR molecules by monoclonal antibodies (mAb) induces protein tyrosine phosphorylation and results in a secondary elevation of free cytoplasmic Ca2+ concentration ([Ca2+]i) in activated human T cells. Here we have studied the effect of

HLA-DQw3 is a broadly defined alloantigen that has been subdivided by serological, biochemical, and molecular methods into three distinct specificities: DQw7, DQw8, and DQw9. In order to characterize functionally relevant structural polymorphisms wit

Alloreactive T-cell clones were used to study allodeterminants associated with the HLA-DR1, DR4 and -DRw14 allelic families. Three clones derived by priming against the DR4,Dw14 alloantigen were tested against a panel of HLA-D homozygous B-cell lines
