Blockage of immune checkpoint molecules increases T-cell priming potential of dendritic cell vaccine.

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
Dendritic cell (DC) -based cancer immunotherapy is one of the most important anti-cancer immunotherapies, and has been associated with variable efficiencies in different cancer types. It is well-known that tumor microenvironment plays a key role in the efficacy of various immunotherapies such as DC vaccine. Accordingly, the expression of programmed death ligand 1 (PD-L1) on DCs, which interacts with PD-1 on T cells, leads to inhibition of anti-tumor responses following presentation of tumor antigens by DCs to T cells. Therefore, we hypothesized that down-regulation of PD-L1 in DCs in association with silencing of PD-1 on T cells may lead to the enhancement of T-cell priming by DCs to have efficient anti-tumor T-cell responses. In this study, we silenced the expression of PD-L1 in DCs and programmed cell death protein 1 (PD-1) in T cells by small interfering RNA (siRNA) -loaded chitosan-dextran sulfate nanoparticles (NPs) and evaluated the DC phenotypic and functional characteristics and T-cell functions following tumor antigen recognition on DCs, ex vivo. Our results showed that synthesized NPs had good physicochemical characteristics (size 77·5 nm and zeta potential of 14·3) that were associated with efficient cellular uptake and target gene silencing. Moreover, PD-L1 silencing was associated with stimulatory characteristics of DCs. On the other hand, presentation of tumor antigens by PD-L1-negative DCs to PD-1-silenced T cells led to induction of potent T-cell responses. Our findings imply that PD-L1-silenced DCs can be considered as a potent immunotherapeutic approach in combination with PD-1-siRNA loaded NPs, however; further in vivo investigation is required in animal models.
