In this study, we investigated the influence of LMP7 on T helper cell differentiation in response to the fungus Candida albicans. We observed a strong effect of ONX 0914, an LMP7-selective inhibitor of the immunoproteasome, on IFN-γ and IL-17A production by murine splenocytes and human peripheral blood mononuclear cells (PBMCs) stimulated with C. albicans in vitro. Using a murine model of systemic candidiasis, we could confirm reduced generation of IFN-γ- and IL-17A-producing cells in ONX 0914 treated mice in vivo. Interestingly, ONX 0914 treatment resulted in increased susceptibility to systemic candidiasis, which manifested at very early stages of infection. Mice treated with ONX 0914 showed markedly increased kidney and brain fungal burden which resulted in enhanced neutrophil recruitment and immunopathology. Together, these results strongly suggest a role of the immunoproteasome in promoting proinflammatory T helper cells in response to C. albicans but also in affecting the innate antifungal immunity in a T helper cell-independent manner.</dcterms:abstract> <dc:contributor>Mundt, Sarah</dc:contributor> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2016-04-20T06:48:30Z</dc:date> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dspace:isPartOfCollection rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/28"/> <dcterms:hasPart rdf:resource="https://kops.uni-konstanz.de/bitstream/123456789/33620/3/Mundt_0-321573.pdf"/> <dc:contributor>Groettrup, Marcus</dc:contributor> <dc:creator>Basler, Michael</dc:creator> <bibo:uri rdf:resource="https://kops.uni-konstanz.de/handle/123456789/33620"/> <dc:contributor>Buerger, Stefanie</dc:contributor> <dc:contributor>Engler, Harald</dc:contributor> <dc:contributor>Basler, Michael</dc:contributor> <dc:language>eng</dc:language> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2016-04-20T06:48:30Z</dcterms:available> <dc:creator>Engler, Harald</dc:creator> <dc:creator>Mundt, Sarah</dc:creator> <dcterms:isPartOf rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/28"/> <dcterms:issued>2016</dcterms:issued> </rdf:Description> </rdf:RDF>
