Abstract
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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
