The immune responses that limit access of these bacteria to underlying tissue remain poorly defined. In this study, we used microarrays to uncover the transcriptional responses that occur in small intestinal \u03b3\u03b4 intraepithelial lymphocytes following bacterial challenge. \u03b3\u03b4 intraepithelial lymphocytes (\u03b3\u03b4 IEL) were isolated by flow cytometry from the small intestines of germ-free mice, or from age- and sex-matched conventionally-raised counterparts. We extracted RNAs from these purified \u03b3\u03b4 IEL for analysis on Affymetrix DNA microarrays. The mice were all >8 weeks in age, and each sample represents a pool of RNAs from 5-8 mice.", "source": "http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-28437", "species": "mouse", "sample_source": "http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-28437/samples/"}
