Bispecific c-Met/PD-1 CAR-T Cells Have Enhanced Therapeutic Effects on Solid Tumor.
Article in Technology in cancer research & treatment. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
ObjectiveTo evaluate the killing effect of c-Met CAR-T on tumor cells with different degrees of c-Met expression. It was demonstrated that CAR-T autocrine PD-1 antibody could alleviate immune checkpoint inhibition and enhance the anti-tumor effect of T cells.MethodsThe specificity and clinical significance of c-Met and PD-L1 expression in various solid tumors were verified by bioinformatics analysis. c-Met specific CAR-T and c-Met specific CAR-T secreted by PD-L1 were synthesized, and c-Met CAR-T and c-Met/PD-1 CAR-T were prepared by constructing lentivirus. Flow cytometry was used to verify the positive rate and cell population of CAR-T, western blot was used to verify the secretion of PD-1 antibody, and cck-8 was used to detect the proliferation of CAR-T in tumor cells with different c-Met expression. LDH and ELISA further evaluated the antitumor effects of c-Met CAR-T and c-Met/PD-1 CAR-T in vitro.Resultsc-Met and PD-L1 were expressed in pancreatic cancer, ovarian cancer, esophageal cancer, bladder cancer, glioma and other tumors, and were associated with a variety of immune cell infiltration. Tumor cells with high expression of c-Met can strongly stimulate the proliferation of c-Met CAR-T, and c-Met CAR-T has strong cell lysis ability on tumor cells with high expression of c-Met. Autocrine PD-1 antibody can significantly improve the activity of c-Met CAR T cells, tumor lysis ability and cytokine secretion level.ConclusionThe antitumor activity of c-Met CAR-T is positively correlated with the expression of c-Met. c-Met CAR-T secreted by PD-1 showed enhanced antitumor function in solid tumor treatment.
