HDX-MS reveals pH and temperature-responsive regions on AAV capsids and the structural basis for DNA release.
Article in Gene therapy, 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
Recombinant adeno-associated viruses (AAVs) have become increasingly popular as gene therapy vectors in recent years. Like all viruses, AAVs undergo dynamic structural changes in response to varying temperature and pH conditions. However, the specific capsid regions involved in these processes remain unknown. In this study, we employed Hydrogen-Deuterium Exchange Mass Spectrometry (HDX-MS) to investigate the impact of pH and temperature on the structure and conformational dynamics of AAV capsids. Our analysis identified specific regions of the capsid that are sensitive to these environmental changes. Additionally, our data elucidated the structural basis for DNA uncoating or leakage triggered by low pH or high temperature. Detailed structural characterization of AAVs by HDX-MS in this study deepens our understanding of viral capsid conformational dynamics and stability in AAV transduction and manufacturing and storage conditions, paving the way for formulation development and next-generation capsid engineering.
