WIF-1 contributes to lupus-induced neuropsychological deficits via the CRYAB/STAT4-SHH axis.

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
backgroundNeuropsychiatric systemic lupus erythematosus (NPSLE) often manifests as cognitive deterioration, with activated microglia and blood-brain barrier (BBB) disruption implicated in these neurological complications. Wnt-inhibitory factor-1 (WIF-1), a secreted protein, has been detected in the cerebrospinal fluid (CSF) of NPSLE patients. However, the contribution of WIF-1 in contributing to lupus cognitive impairment remains poorly understood.
methodsUsing MRL/MpJ-Faslpr (MRL/lpr) lupus-prone mice and TLR7 agonist imiquimod (IMQ)-induced lupus mice, recombinant WIF-1 protein (rWIF-1) and adeno-associated virus (AAV) encoding sh-WIF-1 were administered via intracerebroventricular injection. Behavioral tests, histopathological examinations, flow cytometry, and molecular biology techniques were employed to investigate the underlying mechanisms.
resultsMicroinjection of rWIF-1 exacerbated cognitive deficits and mood abnormalities, increased BBB leakage and neuronal degeneration, and caused aberrant activation of microglia and synaptic pruning in the hippocampus. Conversely, lupus mice injected with AAV-shWIF-1 exhibited significant remission. In vitro, rWIF-1 induced overactivation of microglia with an increased CD86
conclusionsIn conclusion, WIF-1 exacerbates lupus-induced cognitive dysfunction in mice by triggering aberrant microglial activation and BBB disruption through the CRYAB/STAT4-SHH axis, highlighting the potential therapeutic effects of SDMA for the treatment of NPSLE.
