Mycobacterium tuberculosis infection triggers epigenetic changes that are enriched in a type I IFN signature.

ABSTRACT: Tuberculosis, a deadly infectious lung disease caused by Mycobacterium tuberculosis (Mtb), remains the leading cause of bacterial disease-related deaths worldwide. Mtb reprograms and disables key antibacterial response pathways, many of which are regulated by epigenetic mechanisms that control the accessibility of chromatin to the transcriptional machinery. Recent reports suggest that host phosphatases, such as PPM1A, contribute to regulating chromatin accessibility during bacterial infections. However, changes in genome-wide chromatin accessibility during Mtb infection and whether PPM1A plays a role in this process remains unknown. Herein, we use combinatorial chromatin accessibility (ATAC-seq) and transcriptomic (RNA-seq) profiling of wild-type, PPM1A knockout and PPM1A overexpres
