1 · What the graph read from it

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.

2 · The registry

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

Tumor-derived extracellular vesicles (EVs) are a class of natural nanocarriers with phospholipid bilayers that show great promise as personalized cancer vaccine platforms due to their ability to carry tumor-specific antigens. However, their immunotherapeutic potential is hindered by limited tissue-specific targeting. In this study, we engineered tumor cell-derived EVs using an immunomodulatory peptide, DP7-C, to generate DP7-C engineered EVs (DP-EVs). These DP-EVs exhibited significantly enhanced accumulation in both lymph nodes and tumor tissues. Additionally, they demonstrated improved cellular uptake and facilitated more efficient endosomal escape. To further enhance the therapeutic efficacy, programmed cell death 1 ligand 1 targeting small interfering RNA (siPD-L1) was loaded into the DP-EVs, resulting in DP-EVs/siPD-L1. This formulation enabled concurrent suppression of PD-L1 expression in both dendritic cells (DCs) and tumor cells. In vivo experiments showed that DP-EVs/siPD-L1 significantly inhibited tumor growth and prolonged survival in tumor-bearing mice. The observed antitumor effect was attributed to the immune activation in the lymph nodes and the remodeling of the immunosuppressive tumor microenvironment (TME). Collectively, our findings demonstrate that DP-EVs/siPD-L1 functions as an effective therapeutic vaccine, which synergistically activates antitumor immunity and reverses immunosuppression through targeted PD-L1 blockade. This engineered EV platform represents a promising and translatable strategy for cancer immunotherapy.
