Neuron-targeted caveolin-1 overexpression attenuates cognitive loss and pathological transcriptome changes in symptomatic Alzheimer's disease models.
Article in Signal transduction and targeted therapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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 devastating neurodegenerative disorder characterized by progressive synaptic loss and cognitive decline. Gene therapy that augments intrinsic neuroprotective pathways offers a promising strategy to mitigate neurodegeneration and prevent further cognitive loss. Caveolin-1 (Cav-1), a membrane lipid raft (MLR) scaffolding protein, regulates multiple pro-growth and pro-survival signaling pathways within plasmalemmal microdomains. Previously, we showed that AAV9-Synapsin-promoted Cav-1 (SynCav1) delivered to presymptomatic AD mice preserved cognitive functions and MLR-associated neurotrophic signaling. However, the therapeutic potential of SynCav1 delivered at the symptomatic stage of AD had not been tested. Therefore, the current study investigated the effect of hippocampal SynCav1 delivery at symptomatic age in two distinct preclinical AD models of amyloid pathology: PSAPP and APPKI mice. Our results demonstrated that SynCav1 delivery to PSAPP and APPKI mice at symptomatic age consistently preserved hippocampal-dependent memory. Transcriptome profiling revealed that PSAPP-SynCav1 mice exhibited a similar transcript profile to age-matched wild-type mice. Gene Ontology enrichment analysis indicated downregulation of neurodegeneration-specific pathways and upregulation of synaptic and cognitive-related pathways in PSAPP-SynCav1 mice. In vitro, SynCav1-transfected mouse primary cortical neurons exhibited increased p-CaMKII and p-CREB expression, suggesting that SynCav1 may protect the CNS by enhancing neuronal and synaptic activity. Furthermore, activity-dependent neuroprotective protein (ADNP) was identified as a potential candidate mediating SynCav1's neuroprotective effects on cognition. Subcellular membrane fractionation revealed that SynCav1 preserved MLR-localized pituitary adenylate cyclase-activating polypeptide type I receptor (PAC1R), a well-known regulator of ADNP expression. Together, these findings highlight SynCav1 as a unique and promising gene therapy candidate in the treatment of AD.
