    Collapse Overview
    To maintain optimal oxygen delivery to tissues, there is constant regulation of respiratory and cardiovascular systems by mechanisms that act on different time scales. On a fast time scale, a small chemosensory organ called the carotid body senses decreases in blood oxygen to increase breathing within seconds. The carotid body can also regulate cardiovascular function acutely, and carotid body hyperactivity contributes to disease progression in hypertension, heart failure, and metabolic syndrome. Using the mouse as our primary model, we aim to identify the molecular mechanisms that mediate the carotid body’s ability to detect changes in blood oxygen as well as other metabolic signals, such as carbon dioxide and acid. One long term goal is to apply this knowledge to manipulating carotid body activity in the treatment of cardiovascular disease and metabolic syndrome.

    Altmetrics Details 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.
