The Nikolajczyk lab reported the first B cell and T cell functional analyses from type 2 diabetes patients and has since identified roles for lymphocyte-associated changes in disease pathogenesis. Lab focus also includes inflammatory complications of type 2 diabetes such as cardiovascular and periodontal disease. The lab complements analyses of human cells with whole animal models of obesity and type 2 diabetes. We anticipate this combination of ” bench to bedside” and “bedside to bench” approaches will move lab-derived insights to the clinic over the short term.
