Nanoparticles Deliver Brain Peptide to Reverse Diet-Induced Cognitive Decline
Polysorbate 80 coated chitosan nanoparticles for delivery of α-melanocyte stimulating hormone analog (NDP-MSH) to the brain reverse cognitive impairment related to neuroinflammation produced by a high-fat diet (HFD).
Background
A high-fat diet (HFD) is known to induce neuroinflammation and subsequent cognitive impairment, contributing to conditions like obesity-related dementia and metabolic syndrome. The α-melanocyte stimulating hormone analog, NDP-MSH, holds therapeutic promise due to its neuroprotective and anti-inflammatory properties, but its delivery across the blood-brain barrier (BBB) remains a significant challenge. This study specifically addresses how to effectively deliver NDP-MSH to the brain to counteract HFD-induced cognitive deficits.
Study Design
Population
Mice with high-fat diet (HFD)-induced neuroinflammation and cognitive impairment, modeling obesity-related dementia and metabolic syndrome.
Intervention
NDP-MSH delivered via nanoparticles (specific dose, route, duration not specified in digest).
Outcome
Reversal of diet-induced cognitive decline.
