Project description:A total of 52 patients were analyzed: 21 of them monoinfected with HCV and 31 coinfected with HIV (HCV/HIV). HCV patients were recruited from Hospital Italiano and Hospital José María Ramos Mejía from Buenos Aires, Argentina, and HCV/HIV patients from Hospital Universitario La Paz, Hospital Infanta Leonor, Hospital Universitario La Princesa, Hospital Puerta de Hierro, from Madrid, Spain. All samples were processed at the National Center for Microbiology (Madrid). Patients were naıve of treatment for HCV. CHC infection was defined by the presence of anti-HCV antibodies in serum and detectable HCV RNA in plasma samples in at least 2 separate occasions. All HIV+ patients had HIV antibodies, CD4+ T-cells counts ≥ 500 cel/mm3 for at least one year before sample collection, and undetectable HIV viral load since they received suppressive antiretroviral treatment (ART) for at least one year. Plasma extracellular vesicles isolation and RNA purification was performed using the ExoRNeasy Serum/Plasma Midi kit (QIAGEN, Cat #77044). EVs were phenol-lysed and total RNA was purified by ethanol-based membrane binding into spin columns. Quality and integrity were evaluated by the Bioanalyzer 2100 with Agilent RNA 6000 Nano kit (Agilent). Small RNA library synthesis and sequencing were performed at Centre for Genomic Regulation (CRG) at Barcelona (Spain). Small RNA libraries were constructed with Illumina’s TruSeq Small RNA kit v.4 (Illumina) and 50nts (1x50) were sequenced in an Illumina HiSeq2500, with a single read approach.

Project description:Analysis of gene-expression profiles by microarrays can be very useful to characterize new potential candidate genes, key regulatory networks, and to define phenotypes or molecular signatures to improve the diagnosis or classification of the disease. We have used this approach in the study of one of the major causes of allergic diseases in Mediterranean countries, the olive pollen response, in order to find differential molecular markers among five clinical groups, Non-allergic, Asymptomatic, Allergic but not to olive pollen, Non-treated, olive pollen allergic patients and Olive pollen allergic patients (under specific-immunotherapy). The results of gene-expression by principal components analysis (PCA) clearly showed five clusters of samples that correlated with the five clinical groups. Analysis of differential gene-expression by multiple testing, and functional analysis by KEGG and Gene-Ontology revealed differential genes and pathways among the 5 clinical groups. The study population comprised 28 subjects, selected from a previous immunological study (Aguerri et al. Eur. J. Inflammation 2012, in press), from Andalusia, who were recruited in 2 olive pollen exposure situations: during (April-June) and outside the pollen season (October-December). We established 5 groups, and 6 subjects from each group were selected for gene-expression analysis: Group 1, non-allergic subjects; Group 2, asymptomatic subjects (diagnosed with olive pollen allergy by skin testing, with no seasonal respiratory symptoms [rhinitis and/or asthma], and who consulted for adverse reaction to drugs); Group 3, patients who were allergic, but not to olive pollen; Group 4, non-treated olive pollenM-bM-^@M-^Sallergic; and Group 5, olive pollenM-bM-^@M-^Sallergic patients (receiving olive pollenM-bM-^@M-^Sspecific immunotherapy).The subjects were unrelated and recruited at the Allergy Service of 4 hospitals in Andalusia (Granada, JaM-CM-)n, Sevilla, and MM-CM-!laga). Olive pollenM-bM-^@M-^Sallergic patients fulfilled the following criteria: seasonal rhinitis and/or asthma from April to June, a positive skin prick test result for O. europaea pollen extract (ALK AbellM-CM-3, Madrid, Spain), and no previous immunotherapy. Informed consent was obtained from each subject. Ethical approval for the study was obtained from the Ethical and Research Committee of the participating hospitals. PBMCs were isolated from heparin-containing peripheral blood samples taken during and outside pollen season, by gradient centrifugation on Lymphoprep (Comercial Rafer, Zaragoza, Spain) following the manufacturerM-bM-^@M-^Ys instructions.

Project description:The poxviruses are a family of linear double-stranded DNA viruses about 130 to 230 kbp, that belong to the family Poxviridae. The poxviruses have an animal origin and have evolved to infect a wide host range. Variola virus (VARV), the causative agent of smallpox, is a poxvirus that infect only humans, but other poxviruses such monkey pox virus and cowpox virus have also across over from animals to infect humans. Therefor understanding the biology of poxviruses can help to devise antiviral strategies. In this study we used a system-based approach to examine the host responses to three different orthopoxviruses, CPXV, VACV and ECTV in the murine macrophage RAW 264.7 cell line.

Project description:Rhesus Monkey is one of the important primate models widely used in the fields of disease mechanism study, pre-clinical test in drug discovery and molecular evolution. However, the majority of rhesus gene annotations were putatively mapped from human genome, with only 10% supported by rhesus EST data.So, to better study the transcriptome, paired-end, strand-specific, poly(A)-positive RNA-Seq were performed in 5 rhesus monkey tissues. 5 tissue samples examined: prefrontal cortex, liver, skeletal muscle, adipose, testis
