Carbapenemase Transmission in Enterobacter cloacae
2026-09-16
Chen et al. characterize carbapenemase-encoding genes, their genomic location, transferability, and strain relatedness in 54 carbapenem-resistant Enterobacter cloacae isolates from eight teaching hospitals in Guangdong, China. The findings identify plasmid-associated blaNDM-1 as a major transmission concern and show how conjugation, antimicrobial susceptibility testing, mobile-element analysis, and ERIC-PCR can be combined to investigate resistance dissemination.

How Kinase Inhibitors Expose p38α to WIP1
2026-09-08
The reference study shows that selected kinase inhibitors can do more than occupy the p38α active site: they can stabilize an activation-loop conformation that makes the regulatory phospho-threonine more accessible to the phosphatase WIP1. This dual-action mechanism offers a structural framework for designing inhibitors that combine catalytic blockade with accelerated kinase dephosphorylation, while also defining important limits for translating the findings into inflammatory or disease-model workflows.
