Professional Interests:

Dr. Guyre's principal research interest is understanding how hormones and cytokines regulate the functional activity of white blood cells including monocytes, macrophages, dendritic cells, and neutrophils. The goal of Dr. Guyre's current research is to elucidate the physiologic interactions between steroid hormones that often regulate immune responses and molecules that activate the immune system such as cytokines and interferons. For example, bacterial infections stimulate the production of cytokines that activate leukocytes, but also feed back via the brain and pituitary to stimulate the release of cortisol from the adrenal gland. Cortisol (as well as related steroids that are used therapeutically as anti-inflammatory agents) then interacts with cytokines to either enhance or inhibit leukocyte activation as needed. Together with collaborators Drs. Pioli, Yeager and Wira,, Dr. Guyre's research team is identifying the mechanisms by which leukocyte receptors and signaling pathways are regulated by hormones and cytokines to enhance the killing of pathogens and/or suppress inflammation in sepsis, autoimmunity and cardiovascular disease.

After Dr. Guyre received his Ph.D from the University of New Hampshire in 1978, he trained as a postodoctoral research associate with Allan Munck in the DMS Department of Physiology. He joined the Physiology faculty in 1980, and has been a Professor of Physiology and of Microbiology/Immunology since 1991.
