In this study we investigated the impact of CCR7 on CD8+ T cell responses by infecting CCR7\u2212\/\u2212 mice with lymphocytic choriomeningitis virus (LCMV). We found that the absence of CCR7 affects the magnitude of an antiviral CTL response during the acute phase, with reduced numbers of virus-specific CTL in all lymphoid and nonlymphoid organs tested. On the single cell level, CCR7-deficient CTL gained full effector function, such that antiviral protection in CCR7-deficient mice was complete, but delayed. Similarly, adoptive transfer experiments using DC from CCR7-deficient or competent mice for the priming of CCR7-positive or CCR7-negative CD8+ T cells, respectively, revealed that ectopic positioning of DC and CTL outside organized T cell zones results in reduced priming efficacy. In the memory phase, CCR7-deficient mice maintained a stable LCMV-specific CTL population, predominantly in nonlymphoid organs, and rapidly mounted protective CTL responses against a challenge infection with a vaccinia virus recombinant for the gp33 epitope of LCMV. Taken together, the CCR7-dependent organization of the T cell zone does not appear to be a prerequisite for antiviral effector CTL differentiation and the sustenance of antiviral memory responses in lymphoid or peripheral tissues.<\/jats:p>","DOI":"10.4049\/jimmunol.173.11.6684","type":"journal-article","created":{"date-parts":[[2014,4,22]],"date-time":"2014-04-22T04:54:49Z","timestamp":1398142489000},"page":"6684-6693","source":"Crossref","is-referenced-by-count":69,"title":["Impact of CCR7 on Priming and Distribution of Antiviral Effector and Memory CTL"],"prefix":"10.1093","volume":"173","author":[{"given":"Tobias","family":"Junt","sequence":"first","affiliation":[{"name":"Institute of Experimental Immunology , Zurich ,","place":["Switzerland"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elke","family":"Scandella","sequence":"additional","affiliation":[{"name":"Research Department, Kantonsspital St. Gallen , St. Gallen ,","place":["Switzerland"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Reinhold","family":"Fo\u0308rster","sequence":"additional","affiliation":[{"name":"Medizinische Hochschule Hannover Institut fu\u0308r Immunologie , Hannover ,","place":["Germany"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philippe","family":"Krebs","sequence":"additional","affiliation":[{"name":"Institute of Experimental Immunology , Zurich ,","place":["Switzerland"]},{"name":"Research Department, Kantonsspital St. Gallen , St. Gallen ,","place":["Switzerland"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefan","family":"Krautwald","sequence":"additional","affiliation":[{"name":"Department of Nephrology and Hypertension, University of Schleswig-Holstein , Campus Kiel, Kiel ,","place":["Germany"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin","family":"Lipp","sequence":"additional","affiliation":[{"name":"Max Delbru\u0308ck Center for Molecular Medicine , Berlin ,","place":["Germany"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hans","family":"Hengartner","sequence":"additional","affiliation":[{"name":"Institute of Experimental Immunology , Zurich ,","place":["Switzerland"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Burkhard","family":"Ludewig","sequence":"additional","affiliation":[{"name":"Institute of Experimental Immunology , Zurich ,","place":["Switzerland"]},{"name":"Research Department, Kantonsspital St. Gallen , St. Gallen ,","place":["Switzerland"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2004,12,1]]},"reference":[{"first-page":"371","volume-title":"Curr.
