We show that dendritic cells (DC) from GALT induce T cell\u2013independent expression of IgA and gut-homing receptors on B cells. GALT-DC\u2013derived retinoic acid (RA) alone conferred gut tropism but could not promote IgA secretion. However, RA potently synergized with GALT-DC\u2013derived interleukin-6 (IL-6) or IL-5 to induce IgA secretion. Consequently, mice deficient in the RA precursor vitamin A lacked IgA-secreting cells in the small intestine. Thus, GALT-DC shape mucosal immunity by modulating B cell migration and effector activity through synergistically acting mediators.<\/jats:p>","DOI":"10.1126\/science.1132742","type":"journal-article","created":{"date-parts":[[2006,11,16]],"date-time":"2006-11-16T16:48:48Z","timestamp":1163695728000},"page":"1157-1160","source":"Crossref","is-referenced-by-count":903,"title":["Generation of Gut-Homing IgA-Secreting B Cells by Intestinal Dendritic Cells"],"prefix":"10.1126","volume":"314","author":[{"given":"J.
