    Key Interests

    • Monocyte proteins as markers of vascular disease in type 2 diabetes
    • The Gut Microbiome: Role in diabetes and associated vascular disease

    Inflammation and oxidative stress are pathogenic mediators of many diseases, especially cardiovascular complications associated with diabetes. Cardiovascular diseases account for nearly 85 percent of deaths in patients with type 2 diabetes mellitus. While presence of cardiovascular disease can be detected, there are no widely accepted biomarkers for screening and identifying individuals at risk for early vascular disease in patients with type 2 diabetes. My research is targeted on circulating monocytes which is a key player initiating atherogenic vascular disease in diabetes. We focus on monocyte proteins which could serve as individual markers or define a characteristic high risk profile. A major area of research in our laboratory is exploring our gut microbial communities to understand its involvement in the regulation of immune-inflammatory pathways. The gut microbiome plays an important role initiating the inflammatory state of insulin resistance through the activity of lipopolysaccharide (LPS), a component of the gram-negative bacterial cell walls, which can trigger the inflammatory process by secretion of inflammatory cytokines. These circulating cytokines interact with specific receptors on cells and activate various signaling pathways leading to vascular dysfunction. We concentrate on the immune-inflammatory response of human monocytes to the gut microbiota at the molecular, genetic and in vivo level.
