Optical control of the antigen translocation by synthetic photo-conditional viral inhibitors.
Article in Chemical science, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
The immune system makes use of major histocompatibility complex class I (MHC I) molecules to present peptides to other immune cells, which can evoke an immune response. Within this process of antigen presentation, the MHC I peptide loading complex, consisting of a transporter associated with antigen processing TAP, MHC I, and chaperones, is key to the initiation of immune response by shuttling peptides from the cytosol into the ER lumen. However, it is still enigmatic how the flux of antigens is precisely coordinated in time and space, limiting our understanding of antigen presentation pathways. Here, we report on the development of a synthetic viral TAP inhibitor that can be cleaved by light. This photo-conditional inhibitor shows temporal blockade of TAP-mediated antigen translocation, which is unleashed upon illumination. The recovery of TAP activity was monitored at single-cell resolution both in human immune cell lines and primary cells. The development of a photo-conditional TAP inhibitor thus expands the repertoire of chemical intervention tools for immunological processes.
