Construction of an anti-programmed death-ligand 1 chimeric antigen receptor and determination of its antitumor function with transduced cells.
Article in Oncology letters, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
A chimeric antigen receptor (CAR) is a type of fusion protein that comprises an antigen-recognition domain and signaling domains. In the present study, a programmed death-ligand 1 (PD-L1)-specific CAR, comprised of a single-chain variable fragment (scFv) derived from a monoclonal antibody, co-stimulatory domains of cluster of differentiation (CD) 28 and 4-1BB and a T-cell-activation domain derived from CD3ζ, was designed. The construction was cloned and packaged into the lentiviral vector pLVX. Flow cytometry confirmed that peripheral blood mononuclear cells were efficiently transduced and that the CAR was successfully expressed on T cells. The cytotoxicity of transduced T cells was detected using PD-L1-positive NCI-H358 bronchioalveolar carcinoma cells and A549 lung adenocarcinoma cells (with a low expression of PD-L1, only in the A549 cells). The results demonstrated mild cytotoxicity at an effector-to-target ratio of 10:1. An ELISA revealed a significant increase in the level of interferon-γ released from T cells transduced with scFv-28Bz when the cells were co-cultured with PD-L1-positive NCI-H358 cells, while interkeukin-2 and tumor necrosis factor-α levels remained unchanged. These data indicated a potential method for the treatment of solid tumors.
