We performed gene expression profile of different B cell populations found in old (18 months old) C57BL/6 female mouse (B1 cells were recovered from both young and old C57BL/6 mice). Mice were nave and healthy (no autoimmunity was detected at the time of the experiment).
Toll-like receptor 7 (TLR7)-driven accumulation of a novel CD11c⁺ B-cell population is important for the development of autoimmunity.

View SamplesRegulatory T (Treg) cells, expressing abundant amounts of the IL-2 receptor (IL-2R), are reliant on IL-2 produced by activated T cells. This feature implied a key role for a simple network based on IL-2 consumption by Treg cells in their suppressor function. However, congenital deficiency in IL-2R results in reduced expression of the Treg lineage specification factor Foxp3, confounding experimental efforts to understand the role of IL-2R expression and signaling in Treg suppressor function. Using genetic gain and loss of function approaches, we demonstrate that IL-2 capture is dispensable for control of CD4+ T cells, but is important for limiting CD8+ T cell activation, and that IL-2R dependent STAT5 transcription factor activation plays an essential role in Treg suppressor function separable from T cell receptor signaling. Overall design: Gene expression profiles in Treg cells with or without an expression of an active form of STAT5 were compared by RNA sequencing. Male 8-wk-old Foxp3Cre-ERT2Rosa26Stat5bCA (STAT5b-CA) and Foxp3Cre-ERT2 (control) mice, nine mice for each experimental group, received a single dose (4 mg) of tamoxifen by oral gavage 4 months before isolation. Splenic CD4+Foxp3(YFP/GFP)+GITRhiCD25hi Treg and CD4+Foxp3(YFP/GFP)-CD62LhiCD44lo T naive cells were double sorted using a BD FACSAria II cell sorter. The T cell subsets isolated from three individual mice in the same experimental group (genotype) was pooled into one biological replicate; three biological replicates were generated. A total of 12 samples, i.e., two genotypes, two cell cypes, and three replicates, was subjected to RNA-seq analysis. Samples were sequenced on the Illumina HiSeq 2500 to an average depth of 27.5 million 50-bp read pairs per sample.

View SamplesWe generated whole genome expression profiles from a homogeneous population of purified pacemaker neurons (ventral Lateral Neurons, LNvs) from wild type and clock mutant Drosophila. The study identifes a group of genes whose expression is highly enriched in LNvs compared to other neurons; and a second group of genes rhythmically expressed in LNvs in a clock-dependent manner.

View SamplesSeveral transcription factors are known to be expressed in discrete regions of the otic vesicle and Dlx5 is one of those that is expressed highly in the presumptive dorsal vestibular region. Mice lacking Dlx5 have vestibular defects. Specifically, they fail to form the endolymphatic duct (a defect visible as early as E10) as well as the anterior and posterior semi-circular canals. The lateral canal does form but is smaller, whereas the saccule, the utricle and the cochlea appear relatively normal. The goal of this study was to use microarrays to identify differentially expressed genes between wild-type and Dlx5-null otic vesicles microdissected from E10 and 10.5 and identify downstream targets of Dlx5 by searching the immediate 3kb promoter regions of the differentially expressed genes for homeodomain binding sites followed by chromatin immunoprecipitation in an otic vesicle-derived cell line over-expressing Dlx5.

View SamplesExtraocular muscles (EOMs) are a highly specialized type of tissue with a wide range of unique properties, including characteristic innervation, development, and structural proteins. Even though EOMs are frequently and prominently involved in thyroid-associated diseases, little is known about the immediate effects of thyroid hormone on these muscles. In order to create a comprehensive profile of changes in gene expression levels in EOMs induced by thyroid hormone, hyperthyroid conditions were simulated by treating adult Sprague-Dawley rats with intraperitoneal injections of 25 g T3 per 100 g body weight over the course of six weeks; subsequently, microarray analysis was used to determine changes in mRNA levels in EOMs from T3-treated animals relative to untreated controls.
