Neutrophils Kill Reactive Oxygen Species-Resistant Pseudomonas aeruginosa by Sphingosine.
Cystic fibrosis (CF) is dominated by chronic inflammation and infection of the lung resulting in lung destruction and early death of patients. The lungs of CF patients are characterized by a massive accumulation of neutrophils. It requires definition why these massive numbers of neutrophils fail to eliminate typical CF pathogens like Staphylococcus aureus and Pseudomonas aeruginosa (P. aeruginosa) in CF lungs. ⋯ The data provide evidence for a new paradigm explaining how neutrophils kill ROS-resistant P. aeruginosa, i.e. by sphingosine that kills P. aeruginosa at low concentrations. This mechanism is defective in CF neutrophils.

The Protective Effect of Cordycepin On Alcohol-Induced Osteonecrosis of the Femoral Head.
Alcohol abuse is known to be a leading risk factor for atraumatic osteonecrosis of the femoral head (ONFH), in which the suppression of osteogenesis plays a critical role. Cordycepin benefits bone metabolism; however, there has been no study to determine its effect on osteonecrosis. ⋯ Cordycepin treatment to enhance osteogenesis may be considered a potential therapeutic approach to prevent the development of alcohol-induced ONFH.
