For this study, we collected tumor tissues from nine HCC patients receiving anti-PD1 monotherapy and conducted RNA sequencing. These findings revealed significant upregulation of GSDME, which is predominantly expressed by tumor-associated macrophages (TAMs), in anti-PD1-resistant patients. Furthermore, patients with elevated levels of GSDME+ macrophages in HCC tissues presented a poorer prognosis. The analysis of single-cell sequencing data and flow cytometry revealed that the suppression of GSDME expression in nontumor cells resulted in a decrease in the proportion of M2-like macrophages within the tumor microenvironment (TIME) of HCC while concurrently augmenting the cytotoxicity of CD8 + T cells. The non-N-terminal fragment of GSDME within macrophages combines with PDPK1, thereby activating the PI3K-AKT pathway and facilitating M2-like polarization. The small-molecule Eliprodil inhibited the increase in PDPK1 phosphorylation mediated by GSDME site 1. The combination of Eliprodil and anti-PD1 was effective in the treatment of both spontaneous HCC in c-Myc + /+;Alb-Cre + /+ mice and in a hydrodynamic tail vein injection model, which provides a promising strategy for novel combined immunotherapy.</p>","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":" ","pages":""},"PeriodicalIF":21.8,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142575319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Psychological inoculation—an intervention intended to help people identify manipulation techniques—is being adopted at scale around the globe. Yet the efficacy of this approach for increasing belief accuracy remains unclear, as prior work uses synthetic materials that do not contain claims of truth. To address this issue, we conducted five studies with 7,286 online participants using a set of news headlines based on real-world true/false content in which we systematically varied the presence or absence of emotional manipulation. Although an emotional manipulation inoculation did help participants identify emotional manipulation, there was no improvement in participants’ ability to tell truth from falsehood. However, when the inoculation was paired with an intervention that draws people’s attention to accuracy, the combined intervention did successfully improve truth discernment (by increasing belief in true content).
