Profile

Dr. Myers received his DVM degree from Tuskegee University in May 1997, and completed his comparative medicine training in 2001 at the University of Michigan. He received his Masters of Public Health in hospital and molecular epidemiology in 2003 from the University of Michigan, and is also a Diplomat of the American College of Laboratory Animal Medicine. Dr. Myers has a joint appointment with the Department of Surgery and the Unit of Laboratory Animal Medicine. Currently, Dr. Myers is Director of the Conrad Jobst Vascular Research Laboratories and is nationally recognized for his expertise in translational animal model development. He is also the current chair of the Institutional Animal Care & Use Committee (IACUC), which is responsible for assessment and oversight of the institution’s Animal Care & Use Program components and facilities, including the review and approval of animal research protocols, evaluation of animal use and housing areas, monitoring and evaluation of animal use practices, review and approval of policies and standards for animal care and use, and investigation of animal welfare concerns. 

 

RESEARCH INTERESTS

Venous thromboembolism (DVT/PE) is a considerable healthcare concern in the United States, especially among the elderly. The incidence of venous thromboembolism (VTE) increases markedly with advancing age. Approximately 600, 000 non-fatal cases of VTE are reported each year, conservatively. The incidence of VTE is 2-7 times higher in those greater than 55 years of age as compared to younger aged groups, and the incidence increases 74% per decade of age over 45 years. The adhesion molecule P-selectin, which is present in platelet alpha-granules and endothelial cell Weibel-Palade bodies, is up-regulated early during thrombosis promoting vein wall inflammation in multiple animal models and humans. The receptor for P-selectin is a glycoprotein expressed on the surfaces of most hematopoietic cells termed P-selectin glycoprotein ligand-1 (PSGL-1).

This receptor is associated with adhesion interactions responsible for the initial rolling of neutrophils and platelets along stimulated vascular endothelium that initiate thrombus formation. Additionally, P-selectin: PSGL-1 interactions are responsible for thrombus amplification. There is a relationship between increased P-selecting: PSGL-1 activity, venous thrombosis, and aging. It is through these interactions during the aging process that promotes an increased risk for DVT. Studies done in our mouse model of venous thrombosis indicate that circulating P-selectin levels and thrombus burden post DVT significantly increase in older animals. Dr. Myers' research laboratory investigates why P-selectin and its prothrombotic tendencies increase with age.
