Lymphatic filariasis: what mice can tell us.

Human lymphatic filariasis is a major tropical disease in which clinical manifestations range from asymptomatic microfilaraemia to chronic pathology. Investigative immunological research into this disease is hampered by the fact that mice are refractory to the full developmental cycle of this parasitic nematode. However, studies using either single-stage infections or immunocompromised mice have greatly added to our knowledge of the filarial-induced immune pathways leading to protective immunity, pathology and immunological tolerance. In this review, Rachel Lawrence discusses the recent advances in our understanding of the immunology of lymphatic filariasis using the mouse model.
