Membrane-wide screening identifies potential tissue-specific determinants of SARS-CoV-2 tropism.
Article in PLoS pathogens, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
While SARS-CoV-2 primarily infects the respiratory tract, clinical evidence indicates that cells from diverse cell types and organs are also susceptible to infection. Using the CRISPR activation (CRISPRa) approach, we systematically targeted human membrane proteins in cells with and without overexpression of ACE2, thus identifying unrecognized host factors that may facilitate viral entry. Validation experiments with replication-competent SARS-CoV-2 confirmed the role of newly identified host factors, particularly the endo-lysosomal protease legumain (LGMN) and the potassium channel KCNA6, upon exogenous overexpression. In orthogonal experiments, we show that disruption of endogenous LGMN or KCNA6 decreases viral infection and that inhibitors of candidate factors can reduce viral entry. Additionally, using clinical data, we find possible associations between expression of either LGMN or KCNA6 and SARS-CoV-2 infection in human tissues. Our results identify potentially druggable host factors involved in SARS-CoV-2 entry, and demonstrate the utility of focused, membrane-wide CRISPRa screens in uncovering tissue-specific entry factors of emerging pathogens.
