Zusammenfassung der Projektergebnisse

Taken together the results presented here suggest that testosterone modulates the immune response in a suppressive manner. In the context of hepatic infection of the liver with E histolytica, the observed decrease in IFN-y is likely to be responsible for the reduced ability of male mice to kill the parasite and to inhibit ALA development. Questions remain whether testosterone directly or indirectly influences the reactivity of NKT cells to produce cytokines when specifically stimulated by glycolipids and which are the signalling pathways. Moreover, future work has to investigate whether similar gender differences concerning NKT cell activation and cytokine production as found in mice are also present in humans.
