Real-Time Flow Cytometry as a Tool to Monitor Cellular Consequences of P2X7 Activation in Multiple Cell Populations Mixed in a Single FACS Tube.

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
The P2X7 receptor is an ATP-gated ion channel expressed by cells of the immune system. In murine T cells, P2X7 activation by high concentrations of ATP or by covalent ADP-ribosylation are potent triggers of cell death. In innate immune cells, such as macrophages or brain microglia, P2X7 is a key regulator of inflammasome activation and the release of mature interleukin 1 beta. ATP-mediated P2X7 activation is accompanied by several direct downstream events, including the influx of calcium, pore formation at the plasma membrane, ectodomain shedding, and cell shrinkage. With this chapter we provide a protocol to monitor all these immediate consequences of P2X7 activation in a time dependent fashion using real-time flow cytometry. We illustrate, for example, how to simultaneously monitor calcium influx and shedding of CD27 in four T cell subpopulations and how to simultaneously analyze calcium influx, pore formation and cell shrinkage in mouse primary microglia. We further provide an extended protocol to compare consequences of P2X7 activation among identical cell populations from two or more different donor mice mixed in a single FACS tube. Taken together, the here presented real-time flow cytometry protocol for measuring P2X7 activation is flexible, scalable and can easily be transferred to other experimental settings.
