Studies indicate that macrophage immune responses in males are depressed after trauma-hemorrhage, whereas they are enhanced in females under such conditions. Nonetheless, the involvement of male and female sex steroids in this gender-dependent dimorphic immune response after trauma-hemorrhage remains unclear. To study this, male C3H/HeN mice were castrated and treated with pellets containing either vehicle, 5α-dihydrotestosterone (DHT), 17β-estradiol, or a combination of both steroid hormones for 14 days before soft tissue trauma (i.e., laparotomy) and hemorrhagic shock (35 ± 5 mmHg for 90 min followed by adequate fluid resuscitation) or a sham operation. Twenty-four hours later the animals were killed, plasma was obtained, and Kupffer cell and splenic and peritoneal macrophage cultures were established. For DHT-treated mice, we observed significantly decreased releases of the proinflammatory cytokines interleukin 1β (IL-1β) and IL-6 by splenic macrophage (−50 and −57%, respectively) and peritoneal macrophage (−51 and −52%, respectively) cultures after trauma-hemorrhage compared with releases by cultures of cells from mice subjected to a sham operation; in contrast, responses of splenic and peritoneal macrophage cultures from other groups subjected to trauma-hemorrhage did not change significantly. In addition, only DHT-treated animals exhibited increased Kupffer cell IL-6 release (+634%). The release of IL-10 in DHT-treated hemorrhaged animals was increased compared with that in sham-operated animals but was decreased in estrogen-treated mice under such conditions. These results suggest that male and female sex steroids exhibit divergent immunomodulatory properties with respect to cell-mediated immune responses after trauma-hemorrhage.
