Systemic administration of endotoxin, which closely mimics the bacteria-induced systemic inflammatory response syndrome (SIRS) can ultimately lead to organ failure. Adrenal gland insufficiency is frequently diagnosed in critically ill patients; however, the underlying mechanisms are still unclear. In the present study, we studied comprehensively the characteristics of adrenal gland dysregulation, including inflammation, leukocyte infiltration and cell death in the adrenal glands in the course of LPS-induced systemic inflammation in mice. LPS enhanced expression of many proinflammatory cytokines, chemokines and adhesion molecules, which resulted in rapid recruitment of leukocytes into the adrenal gland. Furthermore, LPS-mediated inflammation was associated with increased apoptosis of adrenocortical and chromaffin cells. Our results performed in mice, suggest that LPS-induced adrenal gland inflammation and cell death might be mechanisms potentially involved in the adrenal gland dysfunction in patients with sepsis.
