Effects of Endotoxin in Normal Human Volunteers
Launched by NATIONAL INSTITUTES OF HEALTH CLINICAL CENTER (CC) · Nov 3, 1999
Current as of December 10, 2023
Endotoxin is a unique molecule because it represents an important probe for investigating the humoral and cellular basis of septic shock. Endotoxin administration to humans provides an opportunity to evaluate the earliest responses that are activated after exposure to an important bacterial component. Many alterations in organ function and circulating mediators can be evaluated in this model. These changes are qualitatively similar to changes that occur during sepsis and septic shock. The applications of new technologies to this model are useful adjuncts to define mechanisms of acute inflam...
