Description
Sensorineural hearing loss affects the majority of the elderly population. Mammalian hair cells (HC) do not regenerate and current stem cell and gene delivery protocols result only in immature hair cells like-cells. For this reason, characterization of the transcriptional cascades that lead to development and survival of inner ear HC is essential for designing molecular-based treatments for deafness. We employed a cell type-specific approach to analyze the transcriptomes of the mouse early postnatal auditory and vestibular sensory epithelia and of hair cells derived from zebrafish model. Overall design: Murine auditory and vestibular epithelia were separated into hair-cells (HCs) and epithelial non-sensory cells (ENSCs) by flow cytometry. Gene expression levels were recorded in independent triplicates from the sorted cells using RNA-seq

We employed a cell type-specific approach to analyze the transcriptomes of the mouse early postnatal auditory and vestibular sensory epithelia and of hair cells derived from zebrafish model. Overall design: We utilized the ppv3b:GFP transgenic zebrafish, which express GFP predominantly in HC. We sorted GFP-positive and negative cells from 5 day post fertilization (dpf) larvae using flow cytometry, and profiled their transcriptomes using RNA-seq

Affymetrix Mouse Genome 430A 2.0 Array (mouse430a2)
Description
An efficient innate immune recognition of the intracellular parasite T. cruzi is crucial for host protection against development of Chagas disease, which often leads to multiple organ damage, particularly the heart leading to cardiomyopathy. Mechanisms modulated by MyD88 have been shown to be necessary for resistance against T, cruzi infection. Recently, Nod-like receptors have been shown to play an important role as innate immune sensors, particularly as they relate to inflammasome function, caspase activation, and inflammatory cytokine production. In this study, we aimed to investigate the participation of innate immune responses in general, and inflammasomes in particular, in heart inflammation and cardiac damage upon infection with the T. cruzi parasite.

Description
RNAseq analysis of BAFF in vitro-stimulated (6 hours) murine nfkb2fl/flCD19-Cre (furtheron designated as REL) and CD19-Cre (furtheron designated as WT) splenic B cells identifies genes regulated by the transcription factor NF-kB2 in BAFF-stimulated B cells. Overall design: Splenic B cells from 12-week old relfl/flCD19-Cre and CD19-Cre littermate mice were isolated by magnetic cell separation from splenic mononuclear cells and stimulated in vitro for 6 hours with BAFF. RNA was isolated and submitted for RNA-sequencing on an Illumina HiSeq2000 instrument for 30 million single-ended reads.

Description
The mechanism of CD4(+) T cell depletion during chronic human immunodeficiency virus type 1 (HIV-1) infection remains unknown. Many studies suggest a significant role for chronic CD4(+) T cell activation. We assumed that the pathogenic process of excessive CD4(+) T cell activation would be reflected in the transcriptional profiles of activated CD4(+) T cells. Here we demonstrate that the transcriptional programs of in vivo activated CD4(+) T cells from untreated HIV(+) individuals are clearly different from those activated CD4(+) T cells from HIV(-) individuals. We observed a dramatic up-regulation of cell cycle-associated and interferon-stimulated transcripts in activated CD4(+) T cells of untreated HIV(+) individuals. Furthermore, we find an enrichment of proliferative and Type I interferon-responsive transcription factor binding sites in the promoters of genes that are differentially expressed in activated CD4(+) T cells of untreated HIV(+) individuals compared to HIV(-) individuals. We confirm these findings by examination of in vivo activated CD4(+) T cells. Taken together, these results suggest that activated CD4(+) T cells from untreated HIV(+) individuals are in a hyper-proliferative state that is modulated by Type I interferons. From these results, we propose a new model for CD4(+) T cell depletion during chronic HIV-1 infection.

RNA-seq analysis of murine eGFP+ relbfl/flnfkb2fl/flCg1-Cre and Cg1-Cre splenic germinal center B cells identifies genes regulated by the transcription factors RELB and p52 (NF-kB2) in germinal center B cells. Overall design: Germinal center B cells from 12-week old relbfl/flnfkb2fl/flCg1-Cre and Cg1-Cre littermate mice immunized with sheep red blood cells (SRBC) were isolated at day 7 after immunization by flow cytometric sorting from splenic mononuclear cells. RNA was isolated, amplified and submitted for RNA-sequencing on an Illumina HiSeq2500 instrument for 35-40 million 2x50 paired-ended reads.
