Methods for the study of innate immunity in Drosophila melanogaster.
From flies to humans, many components of the innate immune system have been conserved during metazoan evolution. This foundational observation has allowed us to develop Drosophila melanogaster, the fruit fly, into a powerful model to study innate immunity in animals. Thanks to an ever-growing arsenal of genetic tools, an easily manipulated genome, and its winning disposition, Drosophila is now employed to study not only basic molecular mechanisms of pathogen recognition and immune signaling, but also the nature of physiological responses activated in the host by microbial challenge and how dysregulation of these processes contributes to disease. Here, we present a collection of methods and protocols to challenge the fly with an assortment of microbes, both systemically and orally, and assess its humoral, cellular, and epithelial response to infection. Our review covers techniques for measuring the reaction to microbial infection both qualitatively and quantitatively. Specifically, we describe survival, bacterial load, BLUD (a measure of disease tolerance), phagocytosis, melanization, clotting, and ROS production assays, as well as efficient protocols to collect hemolymph and measure immune gene expression. We also offer an updated catalog of online resources and a collection of popular reporter lines and mutants to facilitate research efforts.

期刊介绍:
Developmental biology is concerned with the fundamental question of how a single cell, the fertilized egg, ultimately produces a complex, fully patterned adult organism. This problem is studied on many different biological levels, from the molecular to the organismal. Developed in association with the Society for Developmental Biology, WIREs Developmental Biology will provide a unique interdisciplinary forum dedicated to fostering excellence in research and education and communicating key advances in this important field. The collaborative and integrative ethos of the WIREs model will facilitate connections to related disciplines such as genetics, systems biology, bioengineering, and psychology.
The topical coverage of WIREs Developmental Biology includes: Establishment of Spatial and Temporal Patterns; Gene Expression and Transcriptional Hierarchies; Signaling Pathways; Early Embryonic Development; Invertebrate Organogenesis; Vertebrate Organogenesis; Nervous System Development; Birth Defects; Adult Stem Cells, Tissue Renewal and Regeneration; Cell Types and Issues Specific to Plants; Comparative Development and Evolution; and Technologies.
