Interaction with immune cells
Phagocytes such as macrophages and neutrophils are key players of the innate immune system and thus constitute the first line of defense against pathogenic Candida species such as C. albicans and C. glabrata. Recognition of Candida cells by phagocytes leads to cytokine production, phagocytosis and the activation of antimicrobial effector functions to induce killing of the fungus. On the other hand, pathogenic Candida spp. are well adapted to their host and have developed mechanisms to evade or counteract the anti-microbial activities of phagocytes. Both fungi are, for example, able to not only survive phagocytosis by macrophages, but even proliferate intracellularly and escape.
We want to characterize the interaction of C. albicans and C. glabrata with phagocytes. We are especially interested in the fungal factors and activities that help Candida to cope with these immune cells and survive.
