Viral peptides that meet the stringent binding characteristics of class I proteins are generated by the 20S proteasome2,3. The interferon (IFN)-γ-inducible activator of the 20S proteasome, PA28 (refs 4–6), strongly influences the proteasomal cleavage pattern in vitro 7. This led us to investigate whether changes in cellular levels of PA28 affect the efficiency of viral antigen processing. A mouse fibroblast line expressing the murine cytomegalovirus pp89 protein was transfected with either the human or murine gene encoding the PA28α subunit, which is sufficient to activate the peptide-hydrolysing activity of the 20S proteasome in vitro. Here we report that enhanced expression of PA28α at a level similar to that obtained after IFN-γ induction resulted in a marked enhancement of recognition by pp89-specific cytotoxic T cells; the presentation of influenza nucleoprotein was also significantly improved. These results demonstrate a fundamental in vivo function for PA28α in antigen processing.</dcterms:abstract> <dc:creator>Schild, Hansjörg</dc:creator> <dc:creator>Rammensee, Hans-Georg</dc:creator> <dc:creator>Dick, Tobias P.</dc:creator> <dc:creator>Eggers, Maren</dc:creator> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/16677"/> <dcterms:issued>1996-05-09</dcterms:issued> <dc:contributor>Eggers, Maren</dc:contributor> <dc:rights>deposit-license</dc:rights> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-11-16T06:37:26Z</dc:date> <dc:creator>Kloetzel, Peter-M.</dc:creator> <dc:contributor>Rammensee, Hans-Georg</dc:contributor> <dc:creator>Kuehn, Lothar</dc:creator> <dcterms:title>A role for the proteasome regulator PA28α in antigen presentation</dcterms:title> </rdf:Description> </rdf:RDF>
