An extracellular vesicle delivery platform based on the PTTG1IP protein.
Article in Extracellular vesicle, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Extracellular vesicles (EVs) are promising therapeutic delivery vehicles, although their potential is limited by a lack of efficient engineering strategies to enhance loading and functional cargo delivery. Using an in-house bioinformatics analysis, we identified N-glycosylation as a putative EV-sorting feature. PTTG1IP (a small, N-glycosylated, single-spanning transmembrane protein) was found to be a suitable scaffold for EV loading of therapeutic cargoes, with loading dependent on its N-glycosylation at two arginine residues. Chimeric proteins consisting of PTTG1IP fused with various cargo proteins, and separated by self-cleaving sequences (to promote cargo release), were shown to enable highly efficient functional delivery of Cre protein to recipient cell cultures and mouse xenograft tumors, and delivery of Cas9-sgRNA complexes to recipient reporter cells. The favorable membrane topology of PTTG1IP enabled facile engineering of further variants with improved properties, highlighting its versatility and potential as a platform for EV-based therapeutics.
