Research Description:

Dr. Nikolajczyk’s current research focuses on the role the immune system plays in obesity and the related co-morbidities of type 2 diabetes and periodontal disease. Her work further queries how changes in fuel sources in these diseases impact immune cell function. She published the first functional analyses of B cells and T cells in type 2 diabetes patients, and her work includes a molecular understanding of mechanisms responsible for pro-inflammatory lymphocyte functions in these patients. Complementary mouse work in Dr. Nikolajczk’s lab rigorously tests concepts identified for humans in a whole animal model. Her work in both human subjects’ material and mouse models demonstrates facility in multiple major experimental approaches and is a strong example of success from concurrent bench-to-bedside and bedside-to-bench work with cross-disciplinary impact.
