This study demonstrates that CD40 is neither involved in Th-dependent nor Th-independent antiviral CTL responses. Moreover, the data show that DC maturation occurs in vivo after viral infection in the absence of CD40 and Th. This maturation did not require viral infection of \u2009DCs but was mediated by peptide-specific CD8+ T cells. Surprisingly, naive CD8+ T cells were able to trigger DC maturation within 24 h after activation in vivo and in vitro. Moreover, peptide-activated CD8+ T cells were able to induce maturation in trans, as DCs that failed to present the relevant antigen in vivo also underwent maturation. Upon isolation, the in vivo\u2013stimulated DCs were able to convert a classically Th-dependent CTL response (anti-HY) into a Th-independent response in vitro. Thus, antiviral CD8+ T cells are sufficient for the maturation of DCs in the absence of CD40.<\/jats:p>","DOI":"10.1084\/jem.189.12.1875","type":"journal-article","created":{"date-parts":[[2002,7,26]],"date-time":"2002-07-26T16:49:30Z","timestamp":1027702170000},"page":"1875-1884","update-policy":"https:\/\/doi.org\/10.1084\/jem.crossmarkpolicy","source":"Crossref","is-referenced-by-count":96,"title":["CD8+
