Rapidly fatal infections.

Emergency physicians are trained to separate "sick" from "not sick" patients during their training. Nevertheless, every emergency physician will face situations in which early intervention is critical to their patient's outcome. Infectious diseases are responsible for many of these potentially poor outcomes.

RAGE modulates peripheral nerve regeneration via recruitment of both inflammatory and axonal outgrowth pathways.

Axotomy of peripheral nerve stimulates events in multiple cell types that initiate a limited inflammatory response to axonal degeneration and simultaneous outgrowth of neurites into the distal segments after injury. We found that pharmacological blockade of RAGE impaired peripheral nerve regeneration in mice subjected to RAGE blockade and acute crush of the sciatic nerve. As our studies revealed that RAGE was expressed in axons and in infiltrating mononuclear phagocytes upon injury, we tested the role of RAGE in these distinct cell types on nerve regeneration.
