Background: The therapeutic management of dementia with Lewy bodies (LBD) is a challenge given the high sensitivity to drugs in this disease. This is particularly sensitive with regard to the management of parkinsonism. In particular, treatment of motor symptoms with levodopa or dopaminergic agonists poses a risk of worsening cognitive and behavioral symptoms.

We and others have used these cortical organoids to model dominantly inherited FTD-tau. While these studies have provided essential insights, cortical organoid models have yet to reach their full potential.

The current study examines whether administration of a novel, brain-penetrant NOX2 inhibitor (CPP11G & CPP11H) reduces amyloid plaque load and improves AD-associated vascular dysfunction in a male APP-PS1 mouse model of AD.
Method: Intraperitoneal injections of CPP11G (n = 1) or CPP11H (n = 2) three times per week began at 9-10 months of age in the treatment APP-PS1 group (15 mg/kg).

Background: Despite some advances in treatment, a cure for Alzheimer's disease (AD) remains elusive. Disease hallmarks include heightened neuroinflammation and oxidative stress, associated with progressive decline in mobility and cognitive functions. Natural compounds provide a valuable reservoir of novel bioactive substances with therapeutic potential, fewer side effects, and increased affordability.

Alzheimers Dement
December 2024
University of Nairobi, Nairobi, Nairobi, Kenya.
Background: The recruitment of individuals for Alzheimer's disease (AD) genetic studies particularly those with low socioeconomic status, and living in rural areas remains a challenge in Sub-Saharan Africa (SSA), due to stigma-related cultural beliefs that hinder their participation. The Recruitment and Retention of Alzheimer's Disease Diversity Genetic Cohorts in the ADSP (READD - ADSP) project is a case-control genetic epidemiological study involving individuals who are living with AD and disease - free healthy control individuals. The aim is to build a resource that greatly expands Alzheimer's disease genetic studies in the currently underrepresented African ancestry populations and Hispanic/Latinx individuals.
