BACE1 Expression Is Required for Proper Synaptic Vesicle Dynamics in the Hippocampus.
Article in Journal of neurochemistry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
BACE1 is an indispensable enzyme for the production of β-amyloid peptides by initiating the cleavage of amyloid precursor protein at the β-secretase site. Targeting BACE1 inhibition is therefore a therapeutic strategy for treating patients with Alzheimer's disease. However, several clinical trials using brain-penetrable BACE1 inhibitors have failed due to a lack of efficacy. Previous studies, including our own, have shown that both global and neuron-specific BACE1 inhibition in mice leads to impairments in synaptic strength and spine density. In this study, we investigate the effects of BACE1 inhibition on activity-dependent synaptic vesicle exocytosis and endocytosis using a synapto-pHluorin mouse model. Our results demonstrate impaired synaptic release in BACE1-deficient mice. Furthermore, transcriptomic analysis reveals a significant downregulation of genes related to synapse structure and function. Pathway analysis suggests that BACE1 deficiency significantly downregulates neurexin-neuroligin pathway, which can modulate docking and release of synaptic vesicles at the presynaptic compartment. Our findings suggest that BACE1 inhibition may lead to deficits in synaptic vesicle exocytosis due to the downregulation of key synaptic proteins.
