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

Plasminogen activation is involved in many processes within the central nervous system, including synaptic plasticity, neuroinflammation and neurodegeneration. However, the mechanisms that regulate plasminogen activation in the brain still remain unknown. Here we demonstrate that astrocytes participate in this regulation by two mechanisms. First, the astrocyte plasma membrane serves as a surface for plasminogen activation by tissue-type plasminogen activator. This activation triggers downstream plasmin-dependent processes with important impacts in brain health and disease, such as fibrinolysis and brain-derived neurotrophic factor conversion. Second, astrocytes take up plasminogen and plasmin in a regulated manner through a novel mechanism involving endocytosis mediated by cell-surface actin and triggered by extracellular plasmin activity at the surface of astrocytes. Following endocytosis, plasminogen and plasmin are targeted to lysosomes for degradation. Thus, cell-surface actin acts as a sensor of plasmin activity to induce a negative feedback through plasmin endocytosis. This study provides evidence that astrocytes control the balance between plasmin formation and plasmin elimination in the brain parenchyma.
