Examining Early Interactions Between Innate Airway Resident Immune Cells And Mtb-Specific Factors During Pulmonary Infection With Mycobacterium Tuberculosis, Micah D. Dunlap
Arts & Sciences Electronic Theses and Dissertations
Mycobacterium tuberculosis (Mtb) is the leading cause of death by an infectious agent in the world today, infecting roughly one quarter of humans. Despite this, the mechanisms of early pathogenesis and host protective innate immune responses remain poorly understood and uncharacterized.
Lung resident Alveolar Macrophages (AMs) are the first host contact with Mtb bacilli after inhalation and are thus key mediators of the early pulmonary immune response. AMs are generally believed to reside entirely in the airway, but it was recently demonstrated that they have the capacity to egress and enter into granulomas during pulmonary infection with hypervirulent Mtb. Furthermore, …
