PHARMACEUTICAL COMPOSITION THAT CELLS WHICH EXPRESS MHC CLASS II ANTIGENS MAKE TARGET CELLS FOR CYTOTOXIC T CELLS.

摘要

The present invention concerns a pharmaceutical composition for treating malignancies and autoimmune diseases involving cells expressing MHC class II antigens. The composition comprises a substance making said cells targets for cytotoxic T cells. The substance may be selected from the group consisting of staphylococcal enterotoxines, toxoids, active fragments or peptides of said enterotoxins and substances having essentially the same mode of action, such as Toxic Shock Syndrome toxins (TSST-1), bacterial exoproteins, such as streptococcal exoproteins, and proteins produced by mycoplasma arthritidis, which have capacity to interact with parts of the TCR and specifically the V beta chains thereof.
