Abstract: Described are generally a T cell immune response cDNA 7 (TIRC7) encoding a novel T-cell transmembrane protein as well as peptides und polypeptides derived therefrom and antibodies recognizing said (poly)peptides. More particularly, peptide and polypeptide as well as antibodies being capable of inhibiting T-cell stimulation through the T-cell membrane protein (TIRC7) are provided. Furthermore, vectors comprising the aforementioned polynucleotides and host cells transformed therewith as well as their use in the production of the above-defined proteins, peptides or polypeptides are described. Additionally, pharmaceutical and diagnostic compositions are provided comprising any one of the afore described polynucleotide, vector, protein, peptide, polypeptide, or antibody. Furthermore, methods and uses for modulating immune responses through the novel TIRC7 membrane protein as well as pharmaceutical compositions comprising agents which act on the TIRC7 membrane protein or its ligand are described.

Abstract: Immortal, antibody-producing, hybridomally-produced clones which produce antibodies that react specifically with human HLA antigens and which are produced from rat lymphocyte cells sensitized against cells from a rat strain having different histocompatibility antigens are disclosed along with methods of producing the clones and antibodies and methods of using the antibodies in tissue crossing tests.
