1 · What the graph read from 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.

2 · The registry

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

Lipid droplets (LDs) are conserved organelles that buffer lipid storage and stress, yet their dynamics and functions in neurons remain largely unknown. Here, we report activity-dependent dynamics of neuronal LDs, visualized by a novel, genetically encoded LD reporter (termed LipiDew), in both cultured neurons and mouse motor cortex. Using LipiDew, we found that various paradigms of neuronal activation induced predominant and transient formation of LDs in neurites. Disruption of autophagic LD degradation (lipophagy) resulted in abnormal lipid accumulation in dendritic spines and shafts, promoted recruitment of synaptic scaffolding proteins to LDs, and altered intracellular calcium kinetics in neurons. In addition, mice with neuron-specific genetic impairment of lipophagy showed motor function defects. Together, these findings identify activity-dependent LD formation and lipophagic clearance in neuronal compartments as a crucial regulatory mechanism of synaptic integrity and neuronal function.
