This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy). This article has been retracted at the request of the Editor-in-Chief. A corrigendum for this article was previously published which corrected issues within Figure 1, as detailed here: https://www.sciencedirect.com/science/article/pii/S1567576920337887?via%3Dihub. The journal was subsequently alerted to additional issues, including an associated PubPeer comment concerning the provenance of the flow cytometry data in Figure 1B, as detailed here: https://pubpeer.com/publications/AD39B667B4ACD09C930F532D0BD985; and here https://docs.google.com/spreadsheets/d/1r0MyIYpagBc58BRF9c3luWNlCX8VUvUuPyYYXzxWvgY/edit#gid=262337249. As part of a journal investigation, the editorial team noticed that many of the Western blots contained within the article were pixelated. In addition, the published email address of the corresponding author (zhangyd78@126.com), differed from the version submitted to the journal (weiwu_drww@163.com). The journal asked the authors to provide a detailed explanation to these concerns and the associated raw data. The Authors did not respond to this request. The Editor-in-Chief assessed the case and decided to retract the article.
