Targeting NLRP3 and Staphylococcal pore-forming toxin receptors in human-induced pluripotent stem cell-derived macrophages.

Staphylococcus aureus causes necrotizing pneumonia by secreting toxins such as leukocidins that target front-line immune cells. The mechanism by which leukocidins kill innate immune cells and trigger inflammation during S. aureus lung infection, however, remains unresolved.

Synthesis of novel 1,2,5-oxadiazoles and evaluation of action against Acinetobacter baumannii.

With multidrug resistant bacteria on the rise, novel antibiotics are becoming highly sought after. In 2008, eleven compounds were identified by high throughput screening as inhibitors of BasE, a key enzyme of the non-ribosomal peptide synthetase pathway found in Acinetobacter baumannii. Herein, we describe the preparation of four structurally similar heterocyclic lead compounds from that study, including one 1,2,5-oxadiazole.

Global Gene Expression Profile of Acinetobacter baumannii During Bacteremia.

Background: Acinetobacter baumannii is a pathogen of major importance in intensive care units worldwide, with the potential to cause problematic outbreaks and acquire high-level resistance to antibiotics. There is an urgent need to understand the mechanisms of A. baumannii pathogenesis for the future development of novel targeted therapies.
