Miltefosine as a PPM1A activator improves AD-like pathology in mice by alleviating tauopathy via microglia/neurons crosstalk.

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 progressively neurodegenerative disease without effective treatment. Here, we reported that the levels of expression and enzymatic activity of phosphatase magnesium-dependent 1A (PPM1A) were both repressed in brains of AD patient postmortems and 3 × Tg-AD mice, and treatment of adeno-associated virus (AAV)-ePHP-overexpression (OE)-PPM1A for brain-specific PPM1A overexpression or the new discovered PPM1A activator Miltefosine (MF, FDA approved oral anti-leishmanial drug) for PPM1A enzymatic activation improved the AD-like pathology in 3 × Tg-AD mice. The mechanism was intensively investigated by assay against the 3 × Tg-AD mice with brain-specific PPM1A knockdown (KD) through AAV-ePHP-KD-PPM1A injection. MF alleviated neuronal tauopathy involving microglia/neurons crosstalk by both promoting microglial phagocytosis of tau oligomers via PPM1A/Nuclear factor-κb (NF-κB)/C-X3-C Motif Chemokine Receptor 1 (CX3CR1) signaling and inhibiting neuronal tau hyperphosphorylation via PPM1A/NLR Family Pyrin Domain Containing 3 (NLRP3)/tau axis. MF suppressed microglial NLRP3 inflammasome activation by both inhibiting NLRP3 transcription via PPM1A/NF-κB/NLRP3 pathway in priming step and promoting PPM1A binding to NLRP3 to interfere NLRP3 inflammasome assembly in assembly step. Our results have highly addressed that PPM1A activation shows promise as a therapeutic strategy for AD and highlighted the potential of MF in treating this disease.
