Validation experiment designed to validate causal mechanisms targeting CHRNA7 in HFD-fed adult Swiss male mice. Primary outcome: rescue of memory performance and reduction of neuroinflammation
HFD-fed mice received intracerebroventricular treatment with PNU-282987, a selective α7 nicotinic acetylcholine receptor agonist, for 3 days to determine if cholinergic activation could mitigate HFD-induced cognitive impairments and neuroinflammation. This pharmacological intervention experiment tested whether targeted activation of α7nAChR could reverse the negative effects of high-fat diet on memory and inflammation in the hippocampal CA3 region. The treatment was administered directly to the brain to ensure specific targeting of central cholinergic receptors.
