Vitamin A and other retinoids inhibit adipogenesis yet can show benefit to skin disorders, such as cystic acne, that are exacerbated by bacteria. We observed that retinoids potently increase and sustain the expression of Camp in preadipocytes undergoing adipogenesis despite inhibition of markers of adipogenesis, such as Adipoq, Fabp4, and Rstn. Retinoids increase cathelicidin in both mouse and human preadipocytes, but this enhancement of antimicrobial peptide expression did not occur in keratinocytes or a sebocyte cell line. Preadipocytes undergoing adipogenesis more effectively inhibited growth of Staphylococcus aureus when exposed to retinoic acid. Whole transcriptome analysis identified hypoxia-inducible factor 1-\u03b1 (HIF-1\u03b1) as a mechanism through which retinoids mediate this response. These observations uncouple the lipid accumulation element of adipogenesis from the innate immune response and uncover a mechanism, to our knowledge previously unsuspected, that may explain therapeutic benefits of retinoids in some skin disorders.<\/jats:p>","DOI":"10.4049\/jimmunol.1900520","type":"journal-article","created":{"date-parts":[[2019,8,16]],"date-time":"2019-08-16T18:35:13Z","timestamp":1565980513000},"page":"1589-1597","source":"Crossref","is-referenced-by-count":32,"title":["Retinoids Enhance the Expression of Cathelicidin Antimicrobial Peptide during Reactive Dermal Adipogenesis"],"prefix":"10.1093","volume":"203","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1402-9245","authenticated-orcid":false,"given":"Marc C","family":"Liggins","sequence":"first","affiliation":[{"name":"Department of Dermatology, University of California , San Diego, La Jolla, CA 92093"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5092-770X","authenticated-orcid":false,"given":"Fengwu","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Dermatology, University of California , San Diego, La Jolla, CA 92093"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ling-juan","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Dermatology, University of California , San Diego, La Jolla, CA 92093"},{"name":"School of Pharmaceutical Sciences, Xiamen University , Xiamen 361102 ,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3678-6781","authenticated-orcid":false,"given":"Tatsuya","family":"Dokoshi","sequence":"additional","affiliation":[{"name":"Department of Dermatology, University of California , San Diego, La Jolla, CA 92093"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1401-7861","authenticated-orcid":false,"given":"Richard L","family":"Gallo","sequence":"additional","affiliation":[{"name":"Department of Dermatology, University of California , San Diego, La Jolla, CA 92093"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2019,9,15]]},"reference":[{"key":"2025030417542204900_r1","first-page":"33","article-title":"Treatment of mice with retinoids in vivo and in vitro.
