Each virus vigorously induced an NK cell infiltrate into the peritoneal cavity and liver, causing some redistributions of NK cell subsets defined by monoclonal antibody (mAb) directed against Ly49A, C\/I, D, and G2. Striking results were seen with a mAb (1F8) reactive with the positively signaling molecule Ly49H, present in MCMV-resistant C57BL\/6 mice. mAb 1F8 also stains Ly49 C and I, but exclusion of those reactivities with mAb 5E6, which recognizes Ly49 C and I, indicated that Ly49H+ cells infiltrated the peritoneal cavity and liver and were particularly effective at synthesizing interferon \u03b3. Depletion of 1F8+ but not 5E6+ cells in vivo by mAb injections enhanced MCMV titers by 20-1,000-fold in the spleen and approximately fivefold in the liver. Titers of LCMV or VV were not enhanced. These anti-MCMV effects were attributed to prototypical NK1.1+CD3\u2212 NK cells and not to NK1.1+CD3+ \u201cNK\/T\u201d cells. This is the first evidence that control of a virus infection in vivo is mediated by a distinct NK cell subset.<\/jats:p>","DOI":"10.1084\/jem.194.1.29","type":"journal-article","created":{"date-parts":[[2002,7,26]],"date-time":"2002-07-26T12:48:33Z","timestamp":1027687713000},"page":"29-44","update-policy":"https:\/\/doi.org\/10.1084\/jem.crossmarkpolicy","source":"Crossref","is-referenced-by-count":346,"title":["Murine Cytomegalovirus Is Regulated by a Discrete Subset of Natural Killer Cells Reactive with Monoclonal Antibody to Ly49h"],"prefix":"10.1084","volume":"194","author":[{"given":"Keith A.","family":"Daniels","sequence":"first","affiliation":[{"name":"aDepartment of Pathology, University of Massachusetts Medical School, Worcester, MA 01655"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gene","family":"Devora","sequence":"additional","affiliation":[{"name":"bDepartment of Pathology, University of Texas Southwestern Medical Center, Dallas, TX 75235"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wayne C.","family":"Lai","sequence":"additional","affiliation":[{"name":"bDepartment of Pathology, University of Texas Southwestern Medical Center, Dallas, TX 75235"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carey L.","family":"O'Donnell","sequence":"additional","affiliation":[{"name":"aDepartment of Pathology, University of Massachusetts Medical School, Worcester, MA 01655"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Bennett","sequence":"additional","affiliation":[{"name":"bDepartment of Pathology, University of Texas Southwestern Medical Center, Dallas, TX 75235"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raymond M.","family":"Welsh","sequence":"additional","affiliation":[{"name":"aDepartment of Pathology, University of Massachusetts Medical School, Worcester, MA 01655"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"291","published-online":{"date-parts":[[2001,6,25]]},"reference":[{"key":"2023072509502213800_R1","first-page":"193","article-title":"Control of infections by NK cells","volume":"230","author":"Tay","year":"1998","journal-title":"Curr.
