Abstract Lipopeptide natural products are essential agents against multidrug-resistant bacteria, but their clinical utility is often constrained by toxicity and resistance. Here, we compare the mechanisms of action of two superficially similar lipopeptide antibiotics: colistin, a last-line treatment for Gram-negative infections, and turnercyclamycins, a new class active against certain colistin-resistant strains.

Abstract We successfully employed a single cell RNA sequencing (scRNA-seq) approach to describe the cells and the communication networks characterizing granulomatous lymph nodes of TB patients. When mapping cells from individual patient samples, clustered based on their transcriptome similarities, we uniformly identify several cell types that characterize human and non-human primate granulomas. Whether high or low Mtb burden, we find the T cell cluster to be one of the most abundant.
