Fast Single-Particle Tracking of Membrane Proteins Combined with Super-Resolution Imaging of Actin Nanodomains.
Article in Scientific data, 2025. 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
Membrane protein dynamics regulates cell functions by initiating downstream signaling cascades. The cell membrane is compartmentalized into nanodomains by actin structures, restricting lateral protein diffusion. Single-particle tracking offers high spatiotemporal resolution for studying protein dynamics in living cells. However, directly observing actin filaments that form barriers of nanodomains for fast protein diffusion is challenging due to their size being below the diffraction limit. Single-molecule localization microscopy resolves these structures but requires imaging in fixed cells. We integrated fast single-particle tracking with single-molecule localization microscopy to generate a dataset of membrane protein dynamics and actin filaments within the same cells at the nanoscales. Optimizing the fixation protocol enabled transition from live-cell tracking to fixed-cell super-resolution imaging. Data for the high-affinity IgE receptor, a transmembrane protein, and the GPI-anchored protein, an outer leaflet protein, was collected at 490 Hz. After fixation, actin filaments were imaged using dSTORM. The treatment of actin structures with phalloidin and PMA generated a dataset of distinct actin architectures for studying their potential influence on membrane protein dynamics.
