Correlates of immune mediated protection to most viral and cancer vaccines are still unknown. This impedes the development of novel vaccines to incurable diseases such as HIV and cancer. In this study, we have used functional genomics and polychromatic flow cytometry to define the signature of the immune response to the yellow fever (YF) vaccine 17D (YF17D) in a cohort of forty volunteers followed for up to one year after vaccination. We show that immunization with YF17D leads to an integrated immune response that includes several effector arms of innate immunity including complement, the inflammasome and interferons, as well as adaptive immunity as shown by an early T cell response followed by a brisk and variable B cell response. Development of these responses is preceded, as demonstrated in three independent vaccination trials and in a novel in vitro system of primary immune responses (Modular IMmune In vitro Construct (MIMIC) system), by the coordinated up-regulation of transcripts for specific transcription factors including STAT1, IRF7 and ETS2 that are upstream of the different effector arms of the immune response. These results clearly show that the immune response to a strong vaccine is preceded by coordinated induction of masters transcription factors, that lead to the development of a broad, polyfunctional and persistent immune response that integrates all effector cells of the immune system.

View SamplesMononuclear phagocytes (MPs), including monocytes and macrophages, play complex roles in the pathogenesis of age-related macular degeneration (AMD). We aimed to perform global transcriptome analysis on monocytes from AMD patients to obtain additional insight to the role of MPs in AMD. Peripheral blood was taken from treatment-nave neovascular AMD (nvAMD) patients (n=14), and age-matched controls (n=15). Peripheral blood mononuclear cells (PBMCs) were separated and monocytes were isolated via negative selection. Gene expression was evaluated with Affymetrix Gene1.0 ST microarrays. Statistical/bioinformatics analysis was performed using open sourceware programs.

View SamplesPhosphorus is an essential macronutrient element, but some time causes problems if present in excess. Unlike the enormous molecular and morphophysiological information available in plants regarding phosphate (Pi) deficiency, little is known about the effect of excess Pi on plants, which is indeed essential for its remediation. Here, we have carried out a comparative study of plant molecular responses under excess Pi (20 mM) or without Pi (0 mM) at transcriptome level. The 1.25 mM treatment concentration of Pi used as a control to obtain differentially regulated genes under above mentioned Pi regimes. A novel whole-transcript expression array, i.e. Arabidopsis Gene 1.0 ST Array, was used to perform these experiments. The most distinctly regulated groups of genes represent modulation in ethylene mediated signaling, Fe deficiency response, and root development. We have also identified some defensin like genes, possessing a gibberellic acid regulated domain (GASA like) under excess Pi treatment. Overall, this study will not only help in dissecting the mechanism of plant responses under excess Pi but also provide the clues about the unknown genes involved in phosphorus homeostasis.

View SamplesWe report gene expression data for the human cell lines HL-60 and PLB-985, which serve as models for human neutrophils. We measured gene expression using RNA-Seq for these cell lines both prior and after differentiation into a neutrophil-like state using two differentiation protocols (treatment with DMSO or treatment with DMSO and replacement of serum with Nutridoma). Overall design: HL-60 and PLB-985 cells grown in culture were processed for RNA-Seq both before and after differentiation for six days in media supplemented with 1.3% dimethyl sulfoxide (DMSO). The cell lines were also analyzed after differentiation for six days in media with 1.3% DMSO, reduced serum (0.5% FBS), and Nutridoma-CS (2%). PLB-985 cells were also analyzed at intermediate time points of 2 days and 4 days with the Nutridoma protocol.

View SamplesBone marrow mesenchymal stem cells (MSC) were adipogenically differentiated followed by dedifferentiation. We are interested to know the new fat markers, adipogenic signaling pathways and dedifferentiation signaling pathways.Furthermore we are also intrested to know that how differentiated cells convert into dedifferentiated progenitor cells. To address these questions, MSC were adipogenically differentiated, followed by dedifferentiation. Finally these dedifferentiated cells were used for adipogenesis, osteogenesis and chondrogenesis. Histology, FACS, qPCR and GeneChip analyses of undifferentiated, adipogenically differentiated and dedifferentiated cells were performed. Regarding the conversion of adipogenically differentiated cells into dedifferentiated cells, gene profiling and bioinformatics demonstrated that upregulation (DHCR24, G0S2, MAP2K6, SESN3) and downregulation (DST, KAT2, MLL5, RB1, SMAD3, ZAK) of distinct genes play a curcial role in cell cycle to drive the adipogenically differentiated cells towards an arrested state to narrow down the lineage potency. However, the upregulation (CCND1, CHEK, HGF, HMGA2, SMAD3) and downregulation (CCPG1, RASSF4, RGS2) of these cell cycle genes motivates dedifferentiation of adipogenically differentiated cells to reverse the arrested state. We also found new fat markers along with signaling pathways for adipogenically differentiated and dedifferentiated cells, and also observed the influencing role of proliferation associated genes in cell cycle arrest and progression.
