Background: Seizures in Alzheimer's Disease (AD) are increasingly recognized to occur and can increase cognitive decline and reduce survival compared to unaffected age-matched peers (Lyou et al. 2018). Administration of antiseizure medicines (ASMs) to AD patients with epileptiform activity may improve cognition (Vossel et al.

Sex hormones regulate gut function and mucosal immunity; however, their specific effects on the mucosa-associated lymphoid tissue (MALT) in the rectum of mammals remain unclear. Here, we aimed to investigate the influence of sex on MALT in the rectum of mammals by focusing on the rectal mucosa-associated lymphoid tissues (RMALTs) of C57BL/6NCrSIc mice. Histological analysis revealed that RMALTs were predominantly located in the lamina propria and submucosa of the rectal mucosa, with a significant sex-related difference in the distance from the anorectal junction to the first appearance of the RMALT.

Such brain health priorities can vary across populations and it is unclear to what degree findings from the ePSOM program in the UK might apply to the US.
Methods: We conducted an online nationwide study to understand what matters to people aged 50 and older about their brain health in the US.

Background: Incretin receptor agonists (IRAs) are synthetic peptides that have beneficial effects within the brain. We investigated IRA brain uptake following two routes of delivery: across the blood-brain barrier (BBB) and following intranasal (IN) delivery.
Method: Radiolabeled IRAs were delivered intravenously or intranasally into CD-1 mice and uptake by or distribution throughout the brain was assessed.

Background: ABCA1-mediated cholesterol transport is a central feature in many lipid- dependent diseases including APOE4-associated Alzheimer's disease and atherosclerosis-CVD. ABCA1 upregulation of RNA transcription by nuclear factors (LXR, RXR) have been associated with liver side-effects because of the common promotor element for ABCA1 and Fatty Acid Synthase. The ABCA1 agonist CS6253, derived from the C-terminal of apoE was designed to stabilize and enhance ABCA1 function, thereby providing a safe alternative to transcriptional upregulation.
