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

Trypanosoma cruzi, the causative agent of Chagas disease, is a parasitic protist that affects millions of people worldwide. Currently there are no fully effective drugs or vaccines available. Contact of T. cruzi infective forms with their host cells or with the extracellular matrix increases their intracellular Ca2+ concentration suggesting a mechano-transduction process. We report here that T. cruzi possesses two distinct mechanosensitive Piezo channels, named TcPiezo1 and TcPiezo2, with different subcellular localizations but similarly essential for normal proliferation, differentiation, and infectivity. While TcPiezo1 localizes to the plasma membrane, TcPiezo2 localizes to the lysosomes. Downregulation of TcPiezo1 expression by a novel ligand-regulated hammerhead ribozyme (HHR) significantly inhibited Ca2+ entry in cells expressing a genetically encoded Ca2+ indicator while downregulation of TcPiezo2 expression inhibited Ca2+ release from lysosomes, which are now identified as novel acidic Ca2+ stores in trypanosomes. The channels are activated by contact with extracellular matrix and by hypoosmotic stress. The results establish the essentiality of Piezo channels for the life cycle and Ca2+ homeostasis of T. cruzi and a novel lysosomal localization for a Piezo channel in eukaryotes.
