However, in advanced HCC, clinical trials have not demonstrated sufficient anti-tumor efficacy, in contrast with preclinical studies. Reverse translation, bedside-to-bench research, is crucial to identify the factors that have hindered GPC3 target immunotherapies.

GPC-3's re-expression in HCC and its involvement in key tumorigenic processes underscore its value as a biomarker for early diagnosis and a target for therapeutic intervention. Further research is warranted to fully exploit GPC-3's diagnostic and therapeutic potential in HCC management.

The protocol includes producing retroviral vectors, generating CAR T cells, and conducting ecto-ADA1 activity, cytotoxicity, cell migration, and RNA sequencing assays. For complete details on the use and execution of this protocol, please refer to Hu et al.1.

Overall, our study successfully generated GPC3 CAR-T cells expressing both IL-21 and CXCL9, demonstrated that combining PD-1 blockade can further enhance CAR-T cell function by promoting proliferation, cytokine secretion, chemotaxis and antitumor activity. These findings present a hopeful and potentially effective strategy for GPC3-positive HCC patients.

The anti-FAP-GPC3 bispecific CAR-T cells also exhibited superior antitumor efficacy and significantly prolonged the survival of mice compared with single-target CAR-T cells in vivo. Overall, the use of anti-FAP-GPC3 bispecific CAR-T cells is a promising treatment approach to reduce tumor recurrence caused by tumor antigen heterogeneity.

In 3D NACs-origami spheroid model of HCC, CAR-Ms were further demonstrated to have a significant tumor killing effect. Together, our study provides a new strategy for the treatment of HCC through CAR-M cells targeting GPC3, which provides a basis for the research and treatment of hepatocellular carcinoma.

The combination of mdivi-1 and CD39 knockdown in CAR-T cells yielded the highest proportion of infiltrated CD39int CAR-T cells and demonstrated a robust antitumor activity in vivo. In conclusion, this study revealed the crucial role of CD39 in CAR-T cell function, demonstrated the potential therapeutic efficacy of combining mdivi-1 with CD39 knockdown in HCC, and provided a novel treatment strategy for HCC patients in the field of cellular immunotherapy.

In this study, lapatinib-resistant cells were used to test the concept of "Evolutionary Traps" and no suitable target stand out because of the identified genes without accessible drug...To test whether this concept is cell line or drug dependent, we analyzed 21 drug-resistant tumor cell expression profiles reveal that JAG1, GPC3, and L1CAM, which are suitable targets for CAR-T treatment, are significantly upregulated in various drug-resistant tumor cells. Our findings shed light on the feasibility of utilizing CAR-T therapy to treat drug-resistant tumors and broaden the concept of the "Evolutionary Trap".

Finally, we revealed that GLUT1 or AGK maintained anti-apoptosis ability in CD8+ T cells via activation of the PI3K/Akt pathway. This finding might identify a therapeutic strategy for advanced HCC.

In conclusion, GPC3-7-19-CAR-T cells achieved antitumor effects superior to those of conventional GPC3-CAR-T cells by reconstructing the TME induced by the dominant CD4 T and CD8 T cell subsets. Most importantly, GPC3-7-19-CAR-T cells exhibited good safety and antitumor efficacy in HCC patients in the clinic. ► Novel GPC3-7-19-CAR-T cells designed with mediate level of IL-7 secretion and high level of CCL19 secretion, which could recruit more mature DCs to assist killing on GPC3HCCs. ►DC cells recruited by CCL19 could interact with CD4 T cells and promote the differentiation of CD4T cells into CD4T and CD8T subsets, leading a better anti-tumor effect on GPC3HCCs. ►Compared with conventional GPC3-CAR-T, GPC3-7-CCL19-CAR-T cells could reverse tumor immunosuppressive microenvironment by reducing PMN-MDSC and Treg cell infiltration.

GPC3 protein is expressed in a large percentage of HB and FLC tumors, but with variable intensity and distribution. Characterization of GPC3 tumor protein H-score and pattern of immunoreactivity are two independent parameters that may be helpful to quantitate GPC3 immunostaining of tumor and correlate with treatment response to a variety of GPC3 targeted therapeutics.

Importantly, STK-009 induced the expression of cytotoxic machinery, pro-survival, and proliferative genes in tumor-infiltrating SYNCAR-002 (figure 3). Conclusions These findings validate that the orthogonal IL-2 platform has the potential to improve the efficacy and durability of CAR T therapy for solid tumor targets such as GPC3 by selectively expanding CAR-T cells in vivo and activating CAR-T cells in a hostile tumor microenvironment.

CT017 CAR T cells were engineered to co-express CAR-GPC3 and runt-related transcription factor 3 (RUNX3), which triggers CD8 T-cell infiltration into the cancer microenvironment...These results need to be confirmed in a robust clinical trial. This study was funded by CARsgen Therapeutics Co., Ltd.
