Effect of interleukin-15 on depressed splenic dendritic cell functions following trauma-hemorrhage.

Trauma-hemorrhage and dendritic cell functions: a critical review of splenic dendritic cell dysfunction following trauma-hemorrhage and therapeutic approach

Abstract Introduction Many studies demonstrated that trauma-hemorrhage induces marked alterations in various immune functions. The trauma-hemorrhage-induced immunosuppression is associated with an increased susceptibility to subsequent sepsis, organ failure and mortality. Previous studies demonstrated that trauma-hemorrhage induces immunosuppression in both innate immune systems and adaptive im...

l-Arginine restores splenocyte functions after trauma and hemorrhage potentially by improving splenic blood flow.

Several studies indicate that immune responses are markedly depressed early after onset of hemorrhage. Decreased organ blood flow has been implicated in the pathophysiology of altered immune responses after trauma-hemorrhage. In this regard, administration ofl-arginine has been shown to restore depressed intestinal and hepatic blood flow after trauma-hemorrhage, probably due to provision of sub...

Splenic Dendritic Cell Functions in Mice Trauma-Hemorrhage Induces Depressed

Testosterone: the culprit for producing splenocyte immune depression after trauma hemorrhage.

Studies indicate that, whereas immune functions in males are depressed, they are enhanced in females after trauma hemorrhage. Moreover, castration of male mice (i.e., androgen depletion) before trauma hemorrhage prevented the depression of cell-mediated immunity. Nonetheless, it remains unknown whether or not testosterone per se is responsible for producing the immune depression. To study this,...

Male sex steroids are responsible for depressing macrophage immune function after trauma-hemorrhage.

Recent studies suggest beneficial effects of castration before soft tissue trauma and hemorrhagic shock on splenocyte immune functions. Nonetheless, it remains unknown whether this effect of testosterone depletion is limited to splenocytes or is a generalized effect on immune function. The present study was therefore carried out to determine whether androgen depletion before trauma-hemorrhage a...
