Healthy Brain Aging

The Women's Healthy Brain Aging Project is a longitudinal study that examines how women's brains change with age. Using a unique methodology, researchers are evaluating the brain status of women by taking multiple, multimodal measurements and relating those measures to cognitive abilities, lifestyle, and genetics. The project aims to provide a comprehensive assessment of brain status and elucidate brain mechanisms underlying resilience across the lifespan.

The Women's Healthy Brain Project was conceived and established by Dr. Angeliki "Lily" Georgopoulos and Dr. Apostolos Georgopoulos in 2010 and continues under the direction of Dr. Lisa James, holder of the Kunin Chair in Women's Healthy Brain Aging at the University of Minnesota. To learn more about the study and how it began, read this feature by Justin Harris and Minnesota Medicine's 2012 Article: The Minnesota Women Healthy Aging Project.

Anomalies in SNIs as assessed by MEG differentiate psychiatric disorders from healthy brain functioning and can discriminate among various brain diseases. From this research, a highly distinctive, unique PTSD SNI signature characterized by miscommunication of temporal and parietal and/or parieto-occipital right hemispheric areas with other brain areas has emerged. These findings, in addition to the growing research applying MEG to other psychiatric disorders, highlight the utility of MEG in identifying biomarkers of disease and underscore the potential for broader clinical applications of MEG. determined by magnetoencephalography Journal of Neurophysiology (2023, March) James L, Leuthold A, Dolan S, & Georgopoulos AP

Most investigations of association of HLA to various diseases have focused on evaluating HLA allele frequencies in diseases of interest, as compared to the general, healthy population. Such studies have demonstrated HLA involvement with cancer, autoimmune, and in- fectious diseases. HLA Class I proteins (HLA-A, B, C) are expressed on all nucleated cells and present peptides from endogenous proteins to cytotoxic T lymphocytes engaged in immune surveillance. HLA Class II proteins (HLA-DRB1, DRB3/4/5, DQB1, DPB1) are expressed on antigen-presenting cells and present peptides derived from exogenous proteins to CD4+helper T cells. A previous study of Gulf War syndrome in 27 veterans found that HLA DRB1*15 was more prevalent in cases than controls with an odds ratio of 1.66, although this association was not statistically significant.

With respect to the number of cysteine residues per mole, E2/2 contains 4, E3/2 contains 3, E4/2 and E3/3 each contain 2, E4/3 contains 1, and E4/4 contains 0.
