Semisynthetic Viral Inhibitor for Light Control of the MHC I Peptide Loading Complex.
Article in Angewandte Chemie (International ed. in English), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 immune system detects virally or malignantly transformed cells via peptide-loaded major histocompatibility complex class I (pMHC I) molecules on the cell surface. MHC I molecules are loaded with cargo peptides in the endoplasmic reticulum (ER) by the highly dynamic multiprotein peptide loading complex (PLC). Here, we developed a semisynthetic approach to generate a photocleavable immune modulator ICP47 of Herpes simplex virus. Using this nanotool, we revealed key mechanistic events of the purified PLC, such as peptide binding and translocation coupled to ATP hydrolysis, triggered by light. We established a single-organelle flow cytometry assay to monitor light-controlled activation of the antigen processing machinery in native ER membranes. This photochemical modulation opens new opportunities for a comprehensive mechanistic analysis of the antigen processing machinery in vitro and native membrane environment.
