Exploring the Structural Divergence of HIV and SRLV Lentiviral Capsids.
Article in Journal of the American Chemical Society, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Lentiviruses require a mature capsid to package and traffic their viral genome for successful infection and propagation. Although the HIV-1 capsid structure has been extensively studied, structural information is lacking for other lentiviral capsids, limiting our understanding. Using cryo-electron microscopy (cryo-EM) and a liposome-templating system, we assembled capsid-like particles (CLPs) and resolved capsid protein (CA) pentamer and hexamer lattice structures from the two major phylogenetic groups of small ruminant lentiviruses (SRLVs). These structures exhibit an overall lattice organization like HIV-1 but differ in key characteristics, notably the absence of inositol hexakisphosphate (IP6) in the SRLV CA lattice─a critical factor for HIV-1 capsid assembly and function. Additionally, SRLV CA pentamers show a unique N-terminal domain orientation, providing insights into SRLV capsid assembly mechanisms. These observations, together with our molecular dynamics (MD) simulation, results suggest a possible mechanism for importing deoxynucleotide triphosphate (dNTP) molecules into SRLV capsids. Furthermore, key regions of host factor interaction, such as the CypA binding motifs, have diverged in the SRLV CA assemblies. Our results contribute to understanding the SRLV lentiviral capsids which may facilitate structure-based inhibitor design strategies.
