Dataset Summary
Title | Host cholesterol modulates the generation and enrichment of persister population during Mycobacterium tuberculosis infection. |
Description | We previously reported that the utilization of host cholesterol is essential for mycobacterial persistence. In this study, we demonstrated that cholesterol-induced activation of a ribonuclease toxin (VapC12) inhibits translation by targeting proT tRNA in Mtb. The resulting cholesterol-specific growth modulation increases the frequency of the generation of persisters in a heterogeneous Mtb population. A vapC12-null mutant strain (ΔvapC12) failed to persist and demonstrated a hypervirulent phenotype in a guinea pig model of Mtb infection. This is the first study to identify a novel strategy through which cholesterol-specific activation of a toxin–antitoxin (TA) module in Mtb enhances persister formation during infection. In addition to identifying the mechanism, the study provides opportunity for targeting persisters, a new paradigm facilitating tuberculosis drug development. |
