Vaccine strategies in RCC have evolved from broad autologous whole tumor antigen (WTA) approaches to defined tumor-associated antigen (TAA) platforms and, more recently, personalized neoantigen vaccines enabled by next-generation sequencing. Early WTA vaccines demonstrated feasibility and immunogenicity, particularly in the adjuvant setting, but failed to consistently improve survival in metastatic disease. TAA-directed vaccines targeting Wilms’ tumor 1, survivin, mucin 1, carbonic anhydrase IX, and 5T4 confirmed on-target immune activation but yielded limited clinical benefit. Personalized neoantigen vaccines, particularly in high-risk resected clear cell RCC, have shown robust and durable T-cell responses with encouraging early clinical signals and are being investigated in larger clinical trials. However, vaccine efficacy in RCC is constrained by tumor-intrinsic immune suppression, heterogeneous antigen presentation, and subtype-specific tumor immune microenvironments. Emerging strategies to further modulate immunosuppressive signals from tumor cells and the microenvironment may enhance vaccine responsiveness, particularly in immune-cold subtypes. Future progress will require stage-specific application, improved antigen selection, and rational combinatorial approaches tailored to RCC biology.</div></div><div>Renal cell carcinoma (RCC) remains one of the most immunologically responsive solid tumors, yet durable benefit from immune checkpoint inhibitors (ICIs) is achieved in only a subset of patients.

However, these therapies show limited efficacy against solid tumors, in part due to the inefficient trafficking of effector cells to the tumor. This review explores the potential of engineering natural and synthetic G protein-coupled receptors (GPCRs) to overcome this migratory hurdle. Chemokine receptors have been the most used GPCR family in this setting. Engineering effector immune cells to express chemokine receptors that match tumor-derived chemokines has been shown to increase their chemotaxis and to improve antitumor efficacy in preclinical models. In addition to improved migration, chemokine receptor engineering can also have additional benefits, such as remodeling of the tumor microenvironment and metabolic rewiring of engineered cells. However, the effectiveness of this approach is limited by the tumor-specific and heterogeneous chemokine milieu. Emerging strategies make use of synthetic GPCRs and could overcome some of these limitations using chemogenetic and optogenetic approaches. Here, mutated GPCRs binding only to specific and orthogonal ligands or light-sensitive channels are used for cell modulation and trafficking. Equipping cells with these synthetic GPCRs allows for precise and stimulus-controlled immune cell migration. Together, natural and synthetic GPCR engineering form promising approaches to enhance immune cell trafficking, persistence, and efficacy.</div></div>","PeriodicalId":73352,"journal":{"name":"Immuno-oncology technology","volume":"29 ","pages":"Article 101582"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146168163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
