Probiotics, naturally extracted substances, medicine, and chemical compounds have been used for wound healing, but the application of postbiotics as therapeutic agents has yet to be explored. Our study shows potential beneficial effects of heat-killed Lactococcus chungangensis CAU 1447 on type 1 diabetic mice. The postbiotic strain significantly decreased the skin wound size. The activity of myeloperoxidase secreted from neutrophils also decreased. The molecular mechanism of wound healing was adjusted by important mediators, growth factors, chemokines, and cytokines. These elements regulated the anti-inflammatory activity and accelerated wound healing. To determine the role of the postbiotic in wound repair, we showed a similar taxonomic pattern as compared to the diabetic mice using skin microbiome analysis. These findings demonstrated that heat-killed Lactococcus chungangensis CAU 1447 had beneficial effects on wound healing and can be utilized as postbiotic therapeutic agents.<\/jats:p>","DOI":"10.3390\/nu13082666","type":"journal-article","created":{"date-parts":[[2021,8,1]],"date-time":"2021-08-01T21:44:32Z","timestamp":1627854272000},"page":"2666","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":54,"title":["Improvement of Cutaneous Wound Healing via Topical Application of Heat-Killed Lactococcus chungangensis CAU 1447 on Diabetic Mice"],"prefix":"10.3390","volume":"13","author":[{"given":"Yohan","family":"Nam","sequence":"first","affiliation":[{"name":"Department of Microbiology, College of Medicine, Chung-Ang University, Seoul 06974, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3343-4820","authenticated-orcid":false,"given":"Jonghwa","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Microbiology, College of Medicine, Chung-Ang University, Seoul 06974, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jihye","family":"Baek","sequence":"additional","affiliation":[{"name":"Department of Microbiology, College of Medicine, Chung-Ang University, Seoul 06974, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9649-3919","authenticated-orcid":false,"given":"Wonyong","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Microbiology, College of Medicine, Chung-Ang University, Seoul 06974, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"409","DOI":"10.1016\/j.imbio.2010.06.007","article-title":"Oleic acid modulation of the immune response in wound healing: A new approach for skin repair","volume":"216","author":"Cardoso","year":"2011","journal-title":"Immunobiology"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"375","DOI":"10.1016\/j.ijpharm.2012.05.044","article-title":"Alginate based bilayer hydrocolloid films as potential slow-release modern wound dressing","volume":"434","author":"Thu","year":"2012","journal-title":"Int.
