Peter Mancuso, PhD, MS

  • Associate Professor, Nutritional Sciences
  • Faculty member, Graduate Program in Immunology

Dr. Mancuso's research focuses on the impact of obesity and diabetes on pulmonary infections and systemic inflammation in chronic disease. We have used lung macrophages, leukocytes from and serum from rodents and humans to study intracellular signaling events, inflammatory mediator synthesis, glucose transport, bactericidal function, and disease outcomes in Midlife women. We have also examined the role of leptin and other adipokines on host defense functions in pulmonary immune cells, in clinical samples from humans with lung diseases, and in serum from human cohorts.

Individuals with obesity and diabetes experience a greater severity of illness from respiratory tract infections. This fact was evident during the current COVID-19 pandemic and Influenza A pandemic of 2009. Dr. Mancuso's research seeks to understand why obesity and diabetes disables host defense against pulmonary infections and to identify potential therapeutic strategies to improve health outcomes. In addition, my lab has examined the role of leptin, an adipokine produced by adipose tissue, in respiratory tract infections. We study the responses of lung macrophages, peripheral blood leukocytes, and serum from rodents and humans after infection to characterize intracellular signaling events, inflammatory mediator synthesis, glucose transport, and bactericidal function. In collaboration with epidemiologist in the Study of Women Across the Nation (SWAN), we have examined associations between leptin and other adipokines with chronic disease outcomes. Current research is focused on the following areas:

  1. The impact of diet induced obesity on glucose transport and bactericidal function in neutrophils.
  2. The role of leptin receptor polymorphisms on neutrophil recruitment and host defense against bacterial pneumonia  
  3. Adipokines as biomarkers for chronic disease risk in Midlife women
