Scabies mites stimulate host inflammatory symptoms via secreted and excreted proteins, which induce basophil and mast cell degranulation and host histamine release. However, the mechanism of degranulation and histamine release is unclear. Moreover, the Sarcoptes scabiei translationally controlled tumor protein (TCTP) is predicted as an excreted protein, which may be involved in host inflammatory response regulation. First, we evaluated S. scabiei TCTP gene (SsTCTP) transcription in larvae, nymphs, and adults by qRT-PCR, and SsTCTP transcription was highest in larvae, followed by nymphs. Second, we found that the S. scabiei TCTP recombinant protein (rSsTCTP) promoted mice histamine release in vivo by Evans blue Miles assay. Therefore, to further explore the possible role of S. scabiei TCTP in host inflammatory response regulation, we established a degranulation model of KU812 cells. The results of the degranulation model suggested that rSsTCTP could induce enhanced degranulation of KU812 cells and increase the secretion of histamine and the expression of IL-4, IL-6, and IL-13 in vitro. In conclusion, we speculate that scabies mites could stimulate host histamine release and Th2 response by excreting S. scabiei TCTP.<\/jats:p>","DOI":"10.3390\/ijms232112865","type":"journal-article","created":{"date-parts":[[2022,10,25]],"date-time":"2022-10-25T22:00:27Z","timestamp":1666735227000},"page":"12865","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Effects of Sarcoptes scabiei Translationally Controlled Tumor Protein (TCTP) on Histamine Release and Degranulation of KU812 Cells"],"prefix":"10.3390","volume":"23","author":[{"given":"Ziyi","family":"Xu","sequence":"first","affiliation":[{"name":"Department of Parasitology, College of Veterinary Medicine, Sichuan Agricultural University, Chengdu 611130, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yanting","family":"Xu","sequence":"additional","affiliation":[{"name":"Department of Parasitology, College of Veterinary Medicine, Sichuan Agricultural University, Chengdu 611130, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaobin","family":"Gu","sequence":"additional","affiliation":[{"name":"Department of Parasitology, College of Veterinary Medicine, Sichuan Agricultural University, Chengdu 611130, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9062-6928","authenticated-orcid":false,"given":"Yue","family":"Xie","sequence":"additional","affiliation":[{"name":"Department of Parasitology, College of Veterinary Medicine, Sichuan Agricultural University, Chengdu 611130, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ran","family":"He","sequence":"additional","affiliation":[{"name":"Department of Parasitology, College of Veterinary Medicine, Sichuan Agricultural University, Chengdu 611130, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jing","family":"Xu","sequence":"additional","affiliation":[{"name":"Department of Parasitology, College of Veterinary Medicine, Sichuan Agricultural University, Chengdu 611130, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bo","family":"Jing","sequence":"additional","affiliation":[{"name":"Department of Parasitology, College of Veterinary Medicine, Sichuan Agricultural University, Chengdu 611130, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xuerong","family":"Peng","sequence":"additional","affiliation":[{"name":"Department of Chemistry, College of Life and Basic Science, Sichuan Agricultural University, Chengdu 611130, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guangyou","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Parasitology, College of Veterinary Medicine, Sichuan Agricultural University, Chengdu 611130, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"64","DOI":"10.1186\/s41182-021-00348-6","article-title":"Scabies as a part of the World Health Organization roadmap for neglected tropical diseases 2021\u20132030: What we know and what we need to do for global control","volume":"49","year":"2021","journal-title":"Trop.
