Summary
Neutrophils are the white blood cells that protect against infection. A surprising protective neutrophil behaviour was recently described – neutrophils can pack up their internal DNA and antimicrobial enzymes and explosively release them into their surrounds, forming a “Neutrophil Extracellular Trap” (NET). This project uses zebrafish built have fluorescent neutrophils to study NET release in living animals. We will learn how NETs control infection and what goes wrong when NETs cause disease.
Cellular And Molecular Mechanisms Of Fungal Infection Pathogenesis And Therapy

Summary
Fungal infections are serious problems for patients with depressed immunity such as chemotherapy or transplant patients. More effective antifungal treatments are needed. We will study a model of fungal infection in zebrafish embryos that recapitulates human penicilliosis. The research will study how the infection establishes and how different types of white blood cells either help or hinder infection establishment. The results will point to new approaches for treating serious fungal infections.

Summary
Dr Lieschke studies white blood cell function and diseases. His biomedical research uses zebrafish animal models of human white blood cell diseases and he is an international expert on their blood and immune systems. His current research aims to understand what goes wrong in diseases when there are too many white blood cells (as in leukaemia), or too few (as in some hereditary diseases), and to develop new therapies for controlling inflammatory and infective diseases.
