POLYNUCLEOTIDE, POLYPEPTIDE WITH IMMUNOSUPPRESIVE ACTIVITY, EXPRESSION CASSETTE, EXPRESSION VECTOR, HOST CELL, PHARMACEUTICAL COMPOSITION, METHODS FOR PRODUCING A POLYPETIDE WITH IMMUNOSUPPRESIVE ACTIVITY AND FOR PREVENTING OR TREATING CONDITIONS THAT REQUIRE IMMUNOSUPPRESION AND USE OF A POLYPEPTIDE

摘要

This invention refers to polynucleotides and non-hemorrhagic and non-immunogenic polypeptides of selective immunosuppressive activity on production of antibodies to antigens of different natures. The polypeptides described herein are useful for preparing pharmaceutical compositions for prevention or treatment of conditions that require immunosuppression, preferably, inflammatory, autoimmune, allergic and infectious diseases and rejection to transplanted organs.
