Microglia TFEB activation attenuates Alzheimer's disease pathology by enhancing autophagy-lysosomal function.

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 characterized by amyloid-β (Aβ) accumulation, neuroinflammation, synaptic dysfunction, and cognitive decline. Impairment of microglial autophagy-lysosomal pathway (ALP) is increasingly recognized as a key driver of the disease progression. Transcription factor EB (TFEB), a master regulator of ALP, has emerged as a promising therapeutic target; however, its specific role in microglia remains unclear. Here, we aimed to determine the therapeutic effects of microglial TFEB expression in AD pathogenesis. We established a tamoxifen-inducible, microglia-specific TFEB-overexpressing 5xFAD mouse line (5xTFEB) and conducted behavioural testing, histopathology and biochemical analyses, live-cell imaging of Aβ phagocytosis, and bulk RNA sequencing. Differential gene expressions were analysed, and inflammasome activation was evaluated. Microglial TFEB overexpression restored ALP function, promoted phagolysosomal clearance of oligomeric Aβ, and reduced the amyloid burden in the cortex, hippocampus, and entorhinal cortex of the 5xFAD mice. These changes rescued memory deficits in both male and female 5xTFEB mice. Transcriptomic profiling revealed upregulation of ALP and downregulation of inflammatory signalling. Additionally, inflammasome activation was attenuated in 5xTFEB mice. Targeted TFEB activation in microglia reprograms degradative and immune pathways, enhancing Aβ clearance while alleviating neuroinflammation and cognitive impairment in AD. Overall, microglial TFEB modulation is a promising cell-type-specific therapeutic strategy for AD and related neurodegenerative disorders.
