A functional genomics approach to the study of avian innate immunity.
A second-generation 4,959 element cDNA microarray has been created and evaluated for its potential use in examining the avian innate immune response. The elements in this array were obtained from EST libraries of stimulated avian PMNC-derived monocytes/macrophages and supplemented by genes of interest from several specific innate immune pathways. The elements are spotted in triplicate resulting in 14,877 total spots per slide. The avian innate immunity microarray (AIIM) contains 25 avian interleukin, chemokine, and cytokine elements. The array also contains elements for several innate immune pathways, including genes involved in the Toll-like receptor (TLR) pathway (including six of the currently known avian TLR receptors), avian interferon/antiviral response pathway genes, and genes involved in apoptosis, antigen presentation and the oxidative burst. The AIIM can be used to evaluate global gene expression patterns in a number of immunologically relevant tissues and in chickens, turkeys and ducks. The array has also been evaluated for its ability to monitor the avian immune response to both bacterial (avian pathogenic Escherichia coli) and viral (avian influenza) avian pathogens.
