1 · What the graph read from it

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.

2 · The registry

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

Lipid bodies (LB; lipid droplets) are cytoplasmic organelles involved in lipid metabolism. Mammalian LBs display an important role in host-pathogen interactions, but the role of parasite LBs in biosynthesis of prostaglandin F2α (PGF2α) has not been investigated. We report herein that LBs increased in abundance during development of Leishmania infantum chagasi to a virulent metacyclic stage, as did the expression of PGF2α synthase (PGFS). The amount of parasite LBs and PGF2α were modulated by exogenous arachidonic acid. During macrophage infection, LBs were restricted to parasites inside the parasitophorous vacuoles (PV). We detected PGF2α receptor (FP) on the Leishmania PV surface. The blockage of FP with AL8810, a selective antagonist, hampered Leishmania infection, whereas the irreversible inhibition of cyclooxygenase with aspirin increased the parasite burden. These data demonstrate novel functions for parasite-derived LBs and PGF2α in the cellular metabolism of Leishmania and its evasion of the host immune response.
