Bortezomib, a proteasome inhibitor, is clinically approved for treatment of multiple myeloma and mantle cell myeloma. In the present study, we investigated the effect of bortezomib on viral infection. Infection of bortezomib-treated mice with the lymphocytic choriomeningitis virus (LCMV) led to a decreased cytotoxic T cell response to several LCMV-derived CD8+ T cell epitopes. Bortezomib treatment caused a reduced expansion of CD8+ T lymphocytes and increased viral titers in LCMV-infected mice. Administration of bortezomib during expansion of CD8+ T cells had no influence on the cytotoxic T cell response, suggesting that bortezomib interferes with priming of naive T cells. Indeed, determination of Ag load in spleen 4 days post infection, revealed a reduced presentation of LCMV-derived cytotoxic T cell epitopes on MHC class I molecules. In summary, we show that proteasome inhibition with bortezomib led to an increased susceptibility to viral infection, and demonstrate for the first time, that proteasome inhibitors can alter Ag processing in vivo.</dcterms:abstract> <dc:rights>deposit-license</dc:rights> <dcterms:bibliographicCitation>Publ. in: The Journal of Immunology 183 (2009), 10, pp. 6145-6150</dcterms:bibliographicCitation> <dc:contributor>Groettrup, Marcus</dc:contributor> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103416863-3868037-7"/> <dc:contributor>Beck, Ulrike</dc:contributor> </rdf:Description> </rdf:RDF>
