Enhanced efficacy of dual chimeric antigen receptor-T cells targeting programmed death-ligand 1 and cancer-associated fibroblasts in colorectal cancer
Article in CytoJournal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: Colorectal cancer (CRC) presents significant treatment challenges, including immune evasion and tumor microenvironment (TME) suppression. Chimeric antigen receptor (CAR) T-cell therapy has shown promise in hematologic malignancies, but its effectiveness against solid tumors is hampered by the detrimental effects of the TME. This article aims to explore the potential of bispecific CAR T cells targeting programmed death-ligand 1 (PD-L1) and cancer-associated fibroblasts (CAFs) in CRC treatment. Material and Methods: Dual-targeted CAR-T cells against PD-L1 and CAF were engineered using the GV400 lentiviral vector. Programmed death-1 (PD-1)/nanobody (Nb) and fibroblast activation protein (FAP)/Nb-encoding lentiviral vectors were generated, and CAR T cells were produced through a three-plasmid system in 293T cells. Human peripheral blood mononuclear cells (PBMCs) were separated, transduced with these vectors, and then expanded. Functional characterization of CAR-T cells was performed through enzyme-linked immunosorbent assay (ELISA), Western blot analysis, flow cytometry, terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assays, and cell counting kit-8 (CCK-8) assay. Migration and invasion assays were conducted using Transwell chambers to assess the ability of FAP-PD-1/Nb CAR-T cells to migrate toward tumor cells and invade the extracellular matrix. Results: We developed dual-targeted CAR-T cells incorporating PD-L1 and CAF Nbs, which continuously secreted PD-1/Nb. Western blot confirmed PD-1/Nb expression in PD-1/Nb and FAP-PD-1/Nb CAR-T cells, with no expression in the untreated (UTD) group ( Conclusion: This study successfully developed dual-targeted CAR-T cells against PD-L1 and CAF and demonstrated their superior antitumor activity and immunomodulatory effects on CRC treatment. This novel therapeutic strategy was established using CAR T-cell technology for the treatment of CRC.
