    摘要: The present invention is related to the field of molecular immunology, particularly to a peptide derived from the sequence of interleukine-15 (IL-15), wherein said peptide was optimized to inhibit the biological activity of this molecule. In the present invention, it is shown that this peptide inhibits IL-15-induced T cell proliferation, Tumor Necrosis Factor α (TNFα) induction and the expression of IL-8 and IL-6 by the IL-15 receptor α subunit (IL-15Rα), all these effects mediated by the binding of the peptide to the IL-15Rα. The invention is also related to the use of the peptide to treat pathologies where the abnormal expression of IL-15 or IL-15Rα is related to the course of the disease, such as rheumatoid arthritis (RA) and prostate cancer.
