Vitamin A and its active metabolite retinoic acid are strongly linked with the modulation of gut immune responses. Here, we describe the temporal changes in the expression of aldehyde dehydrogenase (ALDH) enzymes, responsible for converting dietary\u2010absorbed vitamin A into the immuno\u2010modulatory retinoic acid in lamina propria leucocytes post\u2010infection. We show that ALDH enzymes are expressed by both colonic macrophages and dendritic cells. Further, during an on\u2010going T. muris infection, ALDH expression is repressed from uninfected levels and only recovers to normal levels following expulsion of the parasite. These results suggest that local regulation of cellular levels of retinoic acid is an important component of infection\u2010driven inflammation.<\/jats:p>","DOI":"10.1111\/pim.12032","type":"journal-article","created":{"date-parts":[[2013,3,18]],"date-time":"2013-03-18T06:32:07Z","timestamp":1363588327000},"page":"229-233","source":"Crossref","is-referenced-by-count":21,"title":["The retinoic acid\u2010producing capacity of gut dendritic cells and macrophages is reduced during persistent<i>T.\u00a0muris<\/i>infection"],"prefix":"10.1111","volume":"35","author":[{"given":"R.
