Ultrasound-Targeted Nanobubbles Codelivering NKP-1339 and miR-142-5p for Synergistic Mitochondrial Immunogenic Cell Death and PD-L1 Inhibition in Cancer Therapy.

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
The combination of chemical immunotherapy and gene therapy holds great promise for malignant tumor treatment. Here, we developed an ultrasound-targeted liposome nanobubbles system (NKP-1339/miR-142-NBs) for precise codelivery of drugs and genes to treat esophageal squamous cell carcinoma (ESCC) with ultrasound-targeted microbubble destruction (UTMD). This study systematically investigated the system's therapeutic mechanisms-including mitochondrial dysfunction induction, immunogenic cell death (ICD), and antitumor immune activation-alongside its pharmacokinetics and targeting efficiency. In an ESCC mouse model, NKP-1339/miR-142-NBs combined with ultrasound markedly suppressed tumor growth (79.72% ± 0.1% vs. NB control 18.79% ± 1.29%) through NKP-1339 triggering ICD and miR-142-5p down-regulating programmed death-ligand 1 (PD-L1) expression, synergistically potentiating immune responses. Furthermore, we found that triggering ICD, including the exposure of calreticulin on the cell membrane, was related to altering mitochondrial fission dynamics in the ESCC cells. The down-regulation of PD-L1 expression by miR-142-5p reactivated CD8
