Recent Advances in the Use ofDrosophila melanogasteras a Model to Study Immunopathogenesis of Medically ImportantFilamentous Fungi

[摘要] Airborne opportunistic fungi, includingAspergillusand other less common saprophytic molds, have recently emerged as important causes of mortality in immunocompromised individuals. Understanding the molecular mechanisms of host-fungal interplay in robust experimental pathosystems is becoming a research priority for development of novel therapeutics to combat these devastating infections. Over the past decade, invertebrate hosts with evolutionarily conserved innate immune signaling pathways and powerful genetics, such asDrosophila melanogaster, have been employed as a means to overcome logistic restrains associated with the use mammalian models of fungal infections. Recent studies inDrosophilamodels of filamentous fungi demonstrated that several genes implicated in fungal virulence in mammals also play a similarly important pathogenic role in fruit flies, and important host-related aspects in fungal pathogenesis are evolutionarily conserved. In view of recent advances inDrosophilagenetics, fruit flies will become an invaluable surrogate model to study immunopathogenesis of fungal diseases.
