In this study, we identify two subsets of myeloid cells that associate with the AFC and are the main producers of these factors during a T-dependent Ab response to alum-precipitated protein in mouse lymph nodes. First CD11c+CD8\u03b1\u2212 dendritic cells located in the perivascular area of the T zone provide about half of the IL-6 mRNA produced in the node together with significant amounts of APRIL mRNA. The number of these cells increases during the response, at least in part due to local proliferation. The second subset comprises Gr1+CD11b+F4\/80+ monocyte\/macrophages. These colonize the medullary cords during the response and are the other main IL-6 mRNA producers and the greatest source of APRIL mRNA. This medullary cord monocyte\/macrophage subset results in local increase of APRIL mRNA that mirrors the polarity of CXCL12 expression in the node. The distribution of these myeloid cell subsets correlates with a gradient of AFC maturation assessed by progressive loss of Ki67 as AFC pass from the B cell follicle along the perivascular areas to the medullary cords.<\/jats:p>","DOI":"10.4049\/jimmunol.0802771","type":"journal-article","created":{"date-parts":[[2009,2,9]],"date-time":"2009-02-09T12:02:33Z","timestamp":1234180953000},"page":"2113-2123","source":"Crossref","is-referenced-by-count":169,"title":["Dendritic Cells and Monocyte\/Macrophages That Create the IL-6\/APRIL-Rich Lymph Node Microenvironments Where Plasmablasts Mature"],"prefix":"10.1093","volume":"182","author":[{"given":"Elodie","family":"Mohr","sequence":"first","affiliation":[{"name":"Medical Research Council Centre for Immune Regulation, University of Birmingham Medical School , Birmingham,","place":["United Kingdom"]}]},{"given":"Karine","family":"Serre","sequence":"additional","affiliation":[{"name":"Medical Research Council Centre for Immune Regulation, University of Birmingham Medical School , Birmingham,","place":["United Kingdom"]}]},{"given":"Rudolf A","family":"Manz","sequence":"additional","affiliation":[{"name":"Department for Humoral Immunology, German Arthritis Research Centre , Berlin,","place":["Germany"]}]},{"given":"Adam F","family":"Cunningham","sequence":"additional","affiliation":[{"name":"Medical Research Council Centre for Immune Regulation, University of Birmingham Medical School , Birmingham,","place":["United Kingdom"]}]},{"given":"Mahmood","family":"Khan","sequence":"additional","affiliation":[{"name":"Medical Research Council Centre for Immune Regulation, University of Birmingham Medical School , Birmingham,","place":["United Kingdom"]}]},{"given":"Deborah L","family":"Hardie","sequence":"additional","affiliation":[{"name":"Medical Research Council Centre for Immune Regulation, University of Birmingham Medical School , Birmingham,","place":["United Kingdom"]}]},{"given":"Roger","family":"Bird","sequence":"additional","affiliation":[{"name":"Medical Research Council Centre for Immune Regulation, University of Birmingham Medical School , Birmingham,","place":["United Kingdom"]}]},{"given":"Ian C M","family":"MacLennan","sequence":"additional","affiliation":[{"name":"Medical Research Council Centre for Immune Regulation, University of Birmingham Medical School , Birmingham,","place":["United Kingdom"]}]}],"member":"286","published-online":{"date-parts":[[2009,2,15]]},"reference":[{"key":"2025032622232066500_R1","first-page":"1193","article-title":"T helper 1 (Th1) and Th2 characteristics start to develop during T cell priming and are associated with an immediate ability to induce immunoglobulin class switching.","volume-title":"J.
