ABSTRACT:
The present invention relates to regulation of antigen presentation by cytokine signaling regulators in antigen presenting cells, such as dendritic cells. The invention provides methods of modulating antigen presentation through modulation of cytokine signaling regulators, such as SOCS (SOCS1-7, CIS), SHP (SHP-1 and SHP-2) or PIAS (PIAS1, PIAS3, PIASx and PIASy). The present invention provides vaccines and therapies in which antigen presentation is enhanced through modulation of cytokine signaling regulators. The present invention also provides a mechanism to break self tolerance in tumor vaccination methods that rely on presentation of self tumor antigens.
