Title M. tuberculosis reprograms HSCs to limit myelopoiesis and impair trained immunity via a type I IFN/iron axis [AERO_SERIES_2]
Organism Mus musculus
Experiment type Expression profiling by high throughput sequencing
Summary A greater understanding of hematopoietic stem cell (HSC) regulation is required for dissecting protective versus detrimental immunity to pathogens that cause chronic infections such as Mycobacterium tuberculosis (Mtb). We have shown that systemic administration of BCG or b-glucan reprograms HSCs in the BM via a type II interferon (IFN-II) or IL1 response, respectively, that confers protective trained immunity against Mtb. Yet, whether BCG/β-Glucan is unique in its ability to induce this protection remains unknown. Herein, we demonstrate that unlike BCG or b-glucan, Mtb reprograms HSCs via IFN-I response that suppresses myelopoiesis and impairs protective trained immunity to Mtb. Mechanistically, IFN-I response dysregulates iron metabolism, depolarizes mitochondrial membrane potential, and induces cell death in myeloid progenitors. Finally, activation of IFN-I/iron axis in myeloid progenitors generates a detrimental trained immunity to Mtb infection. These results identify an unanticipated immune evasion strategy of Mtb in the bone marrow that controls the magnitude and anti-microbial capacity of innate immunity to infection
Overall design Single cell RNA expression profiles of LKS+, and cKit+ progenitor cells of Control mice, and mice subject to an aerosol challenge with M.tuberculosis.
