Remimazolam alleviates hippocampal neuronal injury in an in vitro Alzheimer's disease model by promoting PINK1/Parkin-mediated mitophagy.
Article in European journal of medical research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by the pathological accumulation of amyloid-β (Aβ) plaques and hyperphosphorylated tau proteins. Remimazolam (RMZ), a novel ultra-short-acting benzodiazepine, exhibits neuroprotective effects by enhancing mitochondrial autophagy independently of traditional GABAergic mechanisms. This study investigates the protective role of RMZ against Aβ1-42-induced neuronal damage through PINK1/Parkin-mediated mitophagy. In hippocampal HT22 cells, RMZ significantly attenuated Aβ1-42-induced cytotoxicity, reduced apoptosis, suppressed reactive oxygen species (ROS) production, and decreased lactate dehydrogenase (LDH) release. Moreover, RMZ ameliorated mitochondrial membrane depolarization and tau hyperphosphorylation, while enhancing mitophagy, evidenced by an increased LC3-II/LC3-I ratio, elevated Beclin-1 expression, and decreased P62 levels. Mechanistically, RMZ upregulated PINK1 and Parkin expression, facilitating mitochondrial recruitment and clearance of damaged mitochondria. Importantly, knockdown of PINK1 abolished RMZ's protective effects, confirming the pathway's specificity. These findings suggest that RMZ promotes mitochondrial homeostasis and offers a promising strategy for AD therapy via PINK1/Parkin-mediated mitophagy.
