We studied the effects of ginseng, an immune-enhancing agent, on conferring immunity against SARS-CoV-2 in transgenic mice expressing the SARS-CoV-2 human angiotensin-converting enzyme 2 (ACE2) receptor. Methods: Human ACE2-transgenic (ACE2-tg) mice were fed ginseng extract for 180 days before they were intranasally infected with SARS-CoV-2. The mortality and morbidity were monitored for 10 days. The amount of antiviral interferon in the lung tissues was measured using enzyme-linked immunosorbent assay (ELISA) kits. Results: Thirty percent of the mice fed ginseng extract prior to infection survived, whereas all those that were not fed ginseng extract prior to infection died. Viral titers in the lungs were significantly lower in mice fed ginseng extract than in those not fed ginseng extract. The induction of antiviral interferon-gamma (IFN-\u03b3) was significantly higher in the lungs of mice fed ginseng extract than in those that were not. Conclusions: Our data indicate that a ginseng-containing diet may enhance immunity against SARS-CoV-2 in a mouse model.<\/jats:p>","DOI":"10.31083\/j.fbl2706180","type":"journal-article","created":{"date-parts":[[2022,6,10]],"date-time":"2022-06-10T02:45:43Z","timestamp":1654829143000},"source":"Crossref","is-referenced-by-count":5,"title":["Ginseng Protects ACE2-Transgenic Mice from SARS-CoV-2 Infection"],"prefix":"10.31083","volume":"27","author":[{"given":"Sang Heui","family":"Seo","sequence":"first","affiliation":[{"name":"Laboratory of Influenza Research, College of Veterinary Medicine, Institute of Influenza Virus, Chungnam National University, 99 Dae-Hak Ro, Yuseong Gu, 34134 Daejeon, Republic of Korea"},{"name":"Institute of Influenza Virus, Chungnam National University, 34134 Daejeon, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"16242","published-online":{"date-parts":[[2022,6,6]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","unstructured":"Dong E, Du H, Gardner L.
