Sag Lab. on Cancer Immunology
OVERVIEW
Metabolic and immune responses are the most basic and important survival requirements in multicellular organisms. Recent studies by us and others have uncovered the strong mutual influence of metabolism and macrophage inflammatory responses. Identifying the underlying mechanisms is a fascinating and vibrant novel research area and its findings will be critical for the design of therapeutic treatments for both metabolic and inflammatory diseases.
