How interleukin-6 helps prevent allergic asthma and atopy by suppressing interleukin-2 signaling

The immune system has a biological telecommunications system—small proteins known as interleukins that send signals among the leukocyte white blood cells to control their defense against infections or nascent cancer. Interleukin-6, or IL-6, is one of these key mediators of inflammation, and it can, as needed, provoke the immune system into attack against pathogens.

Smart surgical implant coatings provide early failure warning while preventing infection

Newly developed “smart” coatings for surgical orthopedic implants can monitor strain on the devices to provide early warning of implant failures while killing infection-causing bacteria, University of Illinois Urbana-Champaign researchers report. The coatings integrate flexible sensors with a nanostructured antibacterial surface inspired by the wings of dragonflies and cicadas.
