While the pharmaceutical industry raced to develop vaccines, the emergence of mutant severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) strains continues to pose a significant threat. Beyond the immediate concerns, the long-term health repercussions of COVID-19 survivors are garnering attention, particularly due to documented cases of cardiovascular issues, liver dysfunction, pulmonary complications, kidney impairments, and notable neurocognitive deficits. Recent studies have delved into the pathophysiological changes in various organs following post-acute infection with murine hepatitis virus-1 (MHV-1), a coronavirus, in mice. One aspect that stands out is the impact on the skin, a previously underexplored facet of long-term COVID-19 effects. The research reveals significant cutaneous findings during both the acute and long-term phases post-MHV-1 infection, mirroring certain alterations observed in humans post-SARS-CoV-2 infection. In the acute stages, mice exhibited destruction of the epidermal layer, increased hair follicles, extensive collagen deposition in the dermal layer, and hyperplasticity of sebaceous glands. Moreover, the thinning of the panniculus carnosus and adventitial layer was noted, consistent with human studies. A long-term investigation revealed the absence of hair follicles, destruction of adipose tissues, and further damage to the epidermal layer. Remarkably, treatment with a synthetic peptide, SPIKENET (SPK), designed to prevent Spike glycoprotein-1 binding with host receptors and elicit a potent anti-inflammatory response, showed protection against MHV-1 infection. Precisely, SPK treatment restored hair follicle loss in MHV-1 infection, re-architected the epidermal and dermal layers, and successfully overhauled fatty tissue destruction. These promising findings underscore the potential of SPK as a therapeutic intervention to prevent long-term skin alterations initiated by SARS-CoV-2, providing a glimmer of hope in the battle against the lingering effects of the pandemic.<\/jats:p>","DOI":"10.3390\/microorganisms12020272","type":"journal-article","created":{"date-parts":[[2024,1,29]],"date-time":"2024-01-29T08:54:03Z","timestamp":1706518443000},"page":"272","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Dermatologic Changes in Experimental Model of Long COVID"],"prefix":"10.3390","volume":"12","author":[{"given":"Hussain","family":"Hussain","sequence":"first","affiliation":[{"name":"Department of Obstetrics, Gynecology and Reproductive Sciences, University of Miami Miller School of Medicine, Miami, FL 33136, USA"},{"name":"Department of Internal Medicine and Infectious Disease, Larkin Community Hospital, Miami, FL 33143, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael J.","family":"Paidas","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Gynecology and Reproductive Sciences, University of Miami Miller School of Medicine, Miami, FL 33136, USA"},{"name":"Department of Biochemistry and Molecular Biology, University of Miami Miller School of Medicine, Miami, FL 33136, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6992-0612","authenticated-orcid":false,"given":"Ramamoorthy","family":"Rajalakshmi","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Gynecology and Reproductive Sciences, University of Miami Miller School of Medicine, Miami, FL 33136, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aya","family":"Fadel","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Ocean University Medical Center\u2014Hackensack Meridian Health, Brick Township, NJ 08724, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Misha","family":"Ali","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology, Sylvester Comprehensive Cancer Center, University of Miami Miller School of Medicine, Miami, FL 33136, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pingping","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, University of Miami Miller School of Medicine, Miami, FL 33136, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-2115-7860","authenticated-orcid":false,"given":"Arumugam R.","family":"Jayakumar","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Gynecology and Reproductive Sciences, University of Miami Miller School of Medicine, Miami, FL 33136, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,27]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (2023, July 20).
