Research Summary:
Howard Fleit is an immunologist whose research focuses on cellular components of the innate immune system. Phagocytic cells, such as macrophages and neutrophils, are members of the innate immune system and have receptors (Fc receptors) on their plasma membranes that bind antibody molecules and thereby bridge the adaptive immune response to cells of the innate immune system. Fleit utilizes biochemical and cell biological techniques to study how different classes of these receptors transduce a signal in the phagocytes to trigger them to release toxic oxygen intermediates, such as superoxide, which can destroy antibody-coated bacteria.
