The parasitophorous vacuole membrane of Toxoplasma gondii: A custom structural framing with smart interior plumbing for resource allocation.
Review in PLoS pathogens, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
In essence, the parasitophorous vacuole (PV) of Toxoplasma is a "Do-It-Yourself" renovation project led by the parasite after invasion of a guest house (the host cell) to install itself surreptitiously in a private and custom-built room, reinforced by drywall (the PV membrane). The function of the PV membrane (PVM) is to keep away the host security guards (immune response, lysosomes) from the parasite while allowing necessary and controlled access to host resources. Inside the PV, Toxoplasma relies on a crew of creative interior designers (the GRA proteins or GRA) to remodel and transform the space into an efficient living and breeding suite. Some GRA set up specialized delivery systems in the PVM (pores) to siphon off groceries (nutrients) from the host cytosol. Other GRA build a complex network of tubules that attach to the PVM (intravacuolar network) to trap large grocery stores (host organelles) inside the PV, ensuring the massive supply of selective food (lipids). In a parallel circuit, specific GRA recruit host proteins at the PVM that shape this membrane and mediate scission (host ESCRT) to engulf more host resources. In addition to this interior layout, Toxoplasma establishes a plumbing system made of PVM tubules that pervade the host cell, which maximizes the surface area for nutrient uptake, and lasso host organelles (lipid droplets, ER) from the surroundings. Finally, the PV acts as a magnet to attract and keep possession of some host organelles (mitochondria, the ER) by hijacking their molecular Velcro (Membrane Contact Sites), allowing the parasite to tap into the host power grid to fuel its own metabolic needs.
