A -translation inhibitor is potentiated by zinc and kills and non-tuberculous mycobacteria.

poses a serious challenge for human health, and new antibiotics with novel targets are needed. Here we demonstrate that an acylaminooxadiazole, MBX-4132, specifically inhibits the -translation ribosome rescue pathway to kill . Our data demonstrate that MBX-4132 is bactericidal against multiple pathogenic mycobacterial species and kills in macrophages.

Dynamic imbalances in cell-type specific striatal ensemble activity during visually guided locomotion.

Locomotion is continuously regulated by an animal's position within an environment relative to goals. Direct and indirect pathway striatal output neurons (dSPNs and iSPNs) influence locomotion, but how their activity is naturally coordinated by changing environments is unknown. We found, in head-fixed mice, that the relative balance of dSPN and iSPN activity was dynamically modulated with respect to position within a visually-guided locomotor trajectory to retrieve reward.

WD-repeat containing protein-61 regulates endometrial epithelial cell adhesion indicating an important role in receptivity.

Endometrial receptivity is crucial for successful embryo implantation during early pregnancy. The human endometrium undergoes remodeling within each menstrual cycle to prepare or become receptive to an implanting blastocyst in the mid-secretory phase. However, the mechanisms behind these changes are not fully understood.

Thiol Stress Fuels Pyrazinamide Action Against .

Pyrazinamide (PZA) is a cornerstone of first-line antitubercular drug therapy and is unique in its ability to kill nongrowing populations of through disruption of coenzyme A synthesis. Unlike other drugs, PZA action is conditional and requires potentiation by host-relevant environmental stressors, such as low pH and nutrient limitation. Despite its pivotal role in tuberculosis therapy, the mechanistic basis for PZA potentiation remains unknown and the durability of this crucial drug is challenged by the emergent spread of drug resistance.
