The immunometabolic topography of tuberculosis granulomas governs cellular organization and bacterial control.

Despite being heavily infiltrated by immune cells, tuberculosis (TB) granulomas often subvert the host response to (Mtb) infection and support bacterial persistence. We previously discovered that human TB granulomas are enriched for immunosuppressive factors typically associated with tumor-immune evasion, raising the intriguing possibility that they promote tolerance to infection. In this study, our goal was to identify the prime drivers for establishing this tolerogenic niche and to determine if the magnitude of this response correlates with bacterial persistence.
