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

backgroundThe transient receptor potential vanilloid 1 (TRPV1) is a cation channel implicated in neurological disorders. Although TRPV1 activation contributes to intracerebral hemorrhage (ICH) pathology, its microglia-specific role and underlying mechanisms remain poorly defined. This study investigates how microglial TRPV1 influences ICH injury.

methodsWe utilized a mouse ICH model alongside microglia-specific TRPV1 knockout mice, BV2 cells, and primary microglial cultures. Interventions included TRPV1 antagonist capsazepine (CPZ), agonist capsaicin (CAP), microglial depletion agent PLX5622, and TRPV1 knockdown. Outcomes were assessed using immunofluorescence, behavioral tests, Western blot, magnetic resonance imaging (MRI), and transmission electron microscopy (TEM).

resultsTRPV1 expression was significantly upregulated post-ICH, primarily in microglia. TRPV1 blockade with CPZ treatment reduced hematoma volume, brain edema, neuronal apoptosis, and improved neurological function, whereas CAP exacerbated injury. These benefits were replicated in microglia-specific TRPV1 knockout mice. Mechanistically, CPZ shifted microglia from a pro-inflammatory (iNOS+) to a regulatory (Arg1+) phenotype and suppressed excessive mitophagy via the Ca

conclusionTRPV1 activation in microglia exacerbates ICH injury by promoting inflammation and disruptive mitophagy. Targeted inhibition of microglial TRPV1 represents a promising therapeutic strategy for ICH.
