The capacity of a specific pMHC-I to elicit T cell responses is deeply influenced by its expression level (quantity) and its immunogenicity (quality). Tumor cells can evade T cell immunity by down-regulating the quantity of pMHC-Is or selectively eliminating highly immunogenic antigenic peptides. Augmenting the quantity or quality of pMHC-Is is essential for tumor immunotherapy. However, the complexity of pMHC-I regulation and tumor heterogeneity pose challenges to clinical strategies. Consequently, developing approaches grounded in comprehensive analyses of pMHC-I regulatory mechanisms remains a focal point in the research of T cell immunity. In this review, we discuss how tumors modulate their surface pMHC-Is through genetic, epigenetic, and proteomic mechanisms and summarize potential therapeutic strategies targeting these mechanisms, which may provide a valuable reference for the development of novel tumor immunotherapies based on pMHC-I modulation. Tumor cells can achieve immune escape by interfering with the quantity and quality of pMHC-Is, and corresponding immunotherapy can also be achieved by the regulation of pMHC-Is.</p>","PeriodicalId":6942,"journal":{"name":"Acta Pharmacologica Sinica","volume":" ","pages":""},"PeriodicalIF":6.9,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144085632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the well-established link between glutamine reliance and tumor progression, the specific role of glutamine transporters in HNSCC remains poorly understood. The alanine-serine-cysteine transporter 2 (ASCT2), a key glutamine transporter, is overexpressed in HNSCC, and its silencing has been shown to reduce intracellular glutamine and glutathione levels, inhibiting tumor growth. These facts suggest that targeting ASCT2-mediated glutamine uptake could offer a promising therapeutic strategy for HNSCC. But no clinically approved drugs directly target ASCT2, and challenges such as the limited stability of antisense oligonucleotides persist. In this study we evaluated the correlation between ASCT2-mediate glutamine metabolism and its impact on HNSCC patients. We established a virtual screening method followed by cytotoxic assays to identify small molecules that specifically target ASCT2. Among the top 15 candidates, we identified yuanhuacine (YC) as the most potent antitumor compound with IC₅₀ values of 1.43, 6.62, and 6.46 μM against HN6, CAL33, and SCC7 cells, respectively. We demonstrated that YC (0.3-5 μM) dose-dependently induced ASCT2 degradation by recruiting the E3 ubiquitin ligase RNF5, inhibiting glutamine uptake in HN6 cells. This disruption led to mitochondrial dysfunction and enhanced the therapeutic efficacy of YC.

Carrimycin could also inhibit the newly synthesized (nascent) viral RNA. In this study we investigated whether carrimycin also inhibited the newly emerged SARS-CoV-2 variants. We showed that carrimycin (1.25-10 µM) dose-dependently inhibited both viral RNA and protein levels in Vero E6 cells. We further demonstrated that carrimycin disrupted the formation of SARS-CoV-2 double membrane vesicles (DMVs), and identified the host transmembrane protein B (TMEM41B) as the key factor involved in this process. Overexpression of TMEM41B increased viral protein levels and mRNA levels, whereas TMEM41B knockdown reduced viral replication including HCoV-229E, HCoV-OC43 and SARS-CoV-2. Moreover, overexpression of TMEM41B partially reversed the inhibitory effect of carrimycin, suggesting that carrimycin indeed exerted antiviral effects through regulation of TMEM41B. We revealed that carrimycin directly bound to TMEM41B and induced its K48 ubiquitination degradation, thereby inhibiting viral replication.

This process is driven by uncontrolled extracellular matrix (ECM) deposition and the development of fibrous connective tissues. Here, we observed that the mRNA expression of Ffar1, the gene encoding G protein-coupled receptor 40 (GPR40), is repressed, while Cd36 is increased in the bronchoalveolar lavage fluid (BALF), which is predominantly composed of alveolar macrophages, of IPF patients. Furthermore, the GPR40 protein was found to be largely adhered to macrophages and was pathologically downregulated in the lungs of bleomycin (BLM)-induced PF model mice (PF mice) compared with those of control mice. Specific knockdown of GPR40 in pulmonary macrophages by adeno-associated virus 9-F4/80-shGPR40 (AAV9-shGPR40) exacerbated the fibrotic phenotype in the PF mice, and activation of GPR40 by its determined agonist compound SC (1,3-dihydroxy-8-methoxy-9H-xanthen-9-one) effectively protected the PF mice from pathological exacerbation. Moreover, Ffar1 or Cd36 gene knockout mouse-based assays were performed to explore the mechanism underlying the regulation of GPR40 activation in pulmonary macrophages with compound SC as a probe. We found that compound SC mitigated pulmonary fibrosis progression by preventing M2 macrophage polarization from exerting profibrotic effects through the GPR40/PKD1/CD36 axis.

We identified several microRNAs (412-5p, 412-3p, 93-3p, 7b-3p, and 204-5p) that were significantly increased in the NAc of Tsn KO mice. As regulator of G-protein signaling 8 (RGS8) is a predicted target gene shared by three of these microRNAs, and expressed in the NAc, we confirmed its reduced expression in this region in Tsn KO mice. Moreover, shRNA-mediated knockdown of RGS8 in the NAc attenuated locomotor sensitization to repeated cocaine administration.

We previously performed affinity maturation based on the parental antibody M912, and constructed the phage display library. In this study we identified four novel human anti-MSLN antibodies (LP12, HP4-11, HP4-41/LP6, and HP4-44/LP2) with varying degrees of enhanced affinity.

The CAR-T variants induced robust cytolytic activity, significant cytokine production, and activation-induced clonal proliferation against various MSLN-positive tumors in vitro, and effectively cleared disseminated tumors in mice. A single administration of the CAR-T variant LP12 potently eradicated various types of MSLN-positive solid tumors, achieved long-term persistence in vivo, effectively prevented tumor recurrence, and exhibited no non-specific toxicity. Therefore, optimizing the affinity of antigen-binding domain in CAR represents a promising strategy for advancing the development of safe and effective CAR-T cell therapies.
