Yassine Lab
The Yassine lab specializes in how changes in lipid metabolism and nutrition affect the brain and risk of developing Alzheimer’s disease (AD). The lab has a specific interest in studying how carrying the APOE4 allele, strongest genetic risk factors for developing AD, and diabetes affect brain lipid metabolism and the response to the diet.

HDL Particles
- In the Brain HDL Program, we study how a deeper understanding of brain apolipoprotein biology can be utilized to make that can slow down the progression of AD and vascular dementia.
- We focus on a pathway to make smaller HDL particles, via ATP binding cassete 1 (ABCA1) and its capacity to regulate endosome formation.
- Our research indicates that the formation of small HDL by ABCA1 in the brain can protect against neurodegenerative diseases, particularly in individuals at risk because of the APOE4 genotype.
Ion Mobility: Define cerebrospinal fluid HDL particle composition, size, concentrations using ion mobility
-
Main Goals
- Develop a deeper understanding of endosomal dysfunction with APOE4 and its relation to brain HDL and ABCA1 activity using basic animal models
- Characterize biomarkers of brain ABCA1 activity using CSF and imaging studies
- Develop drugs based on increasing brain ABCA1 activity
4. Define cerebrospinal fluid HDL particle composition, size, concentrations using ion mobility
- Define post-translational modifications of brain apolipoproteins in cerebrospinal fluid and their effect on brain HDL structure and function :

AD Biomarkers

Diabetes Brain Program
- In this program we study how obesity and diabetes affect the brain, and explore nutritional and lifestyle interventions to counteract the effect of diabetes and obesity on cognition.
- This program helps fill a research gap by studying the effects of diabetes and obesity on Los Angeles Latinx population.
- The project takes advantage of the resources, population and expertise of the Roybal Dementia Program led by Dr. Yassine at the Roybal Comprehensive Healthcare Clinic in East Los Angeles in collaboration with the USC Alzheimer Disease Research Center at Keck School of Medicine led by Dr. Helena Chui. This clinic is run by the Los Angeles County Department of Health Services (DHS) and serves a predominantly Latinx population.
