Tuberculosis (TB), a disease caused by Mycobacterium tuberculosis (Mtb) infection, remains one of the biggest infectious disease threats and a leading cause of death worldwide. The lack of understanding of the nature of protective immunity against TB hinders the development of an effective vaccine. Macrophages are the most abundant host cells at site of Mtb infection and have been implicated in both disease control and progression. Moreover, the complexity of macrophages is reflected by their origins, heterogeneity and metabolism, all of which govern the functions of these cells in various tissues under homeostatic and inflammatory conditions. We have demonstrated that lung macrophages with distinct developmental lineages acquire unique metabolic states and exhibit differential levels of permissiveness to Mtb survival and growth at early stages of infection. These studies provided the evidence that cell-intrinsic features of differing subsets of lung macrophages dominate the host response to Mtb infection. The overall goal of my laboratory is to define the protective immunity against Mtb. We focus on the biology of lung macrophages and aim to understand the ontogeny and immunometabolism of those cells during Mtb infection. Ultimately, this knowledge will inform the development of vaccines and novel therapeutic interventions against this pathogen. Moreover, these studies may also have a broad impact on other pulmonary diseases.
