Overview
overview
Research in my laboratory is broadly directed at elucidating the molecular details of mammalian innate immunity, particularly in the gastrointestinal tract. We use a combination of in vitro and in vivo approaches to analyze the host factors that influence the response to infection with Salmonella typhimurium, an important agent of acute gastroenteritis in humans. In an on-going series of experiments, we are attempting to elucidate the effects of altered iron metabolism on macrophage function in salmonellosis. These studies have revealed a novel role for intracellular iron in the regulation of inflammatory cytokine biosynthesis, and have important implications for our understanding of host-pathogen interactions in conditions such as hemochromatosis.

PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
