Peripheral amylin modulation rebalances brain glycolysis and Tau-Ser214 phosphorylation via cAMP-PKA signaling.

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
Brain glucose dysregulation is shared by Alzheimer's disease (AD) and diabetes, but whether it arises from central or peripheral mechanisms remains unclear. Amylin, a pancreatic hormone, normally supports CNS cAMP-PKA signaling, metabolism and memory; however, prediabetes-associated hypersecretion disrupts this balance. Using human amylin-inducible mice, we show that toggling amylin secretion during metabolic stress bidirectionally regulates brain glycolysis and function. Excess amylin overactivates cAMP-PKA signaling, suppressing glycolysis and inducing Tau-Ser214 phosphorylation, two core features of AD pathology. This state is accompanied by activation of the amino acid starvation response, Tau-T231 hyperphosphorylation, pTau-Aβ coupling, neuroinflammation and memory deficit. In contrast, reducing amylin in prediabetes preserves glycolysis, ATF4-dependent proteostasis and cognition. Astrocytes emerge as primary targets, as amylin receptor blockade prevents glycolytic deficits
