Project description:We have analyzed six different extracelular vesicles isolation protocols from plasma of patients coinfected with human immunodeficiency virus and hepatitis C virus (HIV/HCV). In addition, two different RNA isolation kit were used for each protocol, one phenol-based and another pehenol-free kit. Same library kit was used for all samples. Small RNA, including miRNAs, piwiRNA, and sncRNAs were detected.

Project description:The seminal plasma contains large quantities of extracellular vesicles (EVs). However, the role of these EVs and their interactions with sperms are not clear. To identify the important molecules affecting sperm motility in EVs, we sequenced the EVs in the seminal plasma of Yorkshire boars with different sperm motility using whole RNA sequence.

Project description:No residual disease after debulking Surgery (R0 resection) is the most critical independent prognostic factor for advanced ovarian cancer (AOC). Therefore, it is of paramount importance to preoperative estimate the likelihood of R0 resection for choosing the best therapeutic strategy. Our study aimed to develop a non-invasive and reliable detection method for AOC patients with a high risk of residual disease. An integrated plasma small extracellular vesicles (sEVs) microRNA profiling was generated by RNA sequencing in AOC patients with no residual disease patients (R0) and residual disease(non-R0). We identified and validated a logistic model based on plasma sEVs miRNAs to predict residual disease in AOC patients.

Project description:Extracellular vesicles play a pivotal role in the intercellular communications influencing various physiological and pathological processes. They carry a range of biomolecular cargoes including small non-coding RNAs which could serve as potential diagnostic biomarkers and therapeutic targets. In the current study we applied Next Generation Sequencing to investigate small RNA profiles of erythrocytes (Rbc), platelets (Plt), leukocytes (CD45cells), two plasma fractions and blood cell-derived extra-cellular vesicles (EVs, such as CD41+, CD45+, CD235a+, CD146+) obtained using high-sensitivity fluorescence activated vesicle sorting from plasma of healthy donors. We analyzed the proportions of various small ncRNAs across samples and identified sample specific profiles of microRNA (miRNA) and transport RNA-derived fragments (tRFs). It was found that the cumulative small ncRNAs profiles of EVs originated from platelets, erythrocytes, and leukocytes, which are considered to be dominant among the vesicles circulating in blood, differ from small ncRNAs profiles of plasma fractions, which represent macrovesicles and exosomes in circulation. The proportion of miRNAs in sorted EVs was significantly lower compared to other samples while the proportion of tRFs was higher. Moreover, all sorted EVs carried mostly cell type non-specific miRNAs. Taking together, the results demonstrate that the combination of high-sensitivity fluorescence activated vesicle sorting with small-RNA sequencing technique is a powerful approach to analyze small ncRNAs profiles in cell specific vesicles.

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:Similar to bacterial proteins that are targeted to distinct macrophages organelles via extracellular vesicles, we propose that these vesicles also traffic small RNAs to modulate specific host factors. To test this, we aim to sequence extracellular vesicle derived sRNA, and whole bacterial small RNAs to determine selectivity, and to identify their bacterial and mammalian targets (Experimental Plan in Table-1). For this we will collect highly purified vesicles from N. gonorrhoeae (strain MS11A). We will also treat mouse derived primary macrophages with extracellular vesicles and compare their RNA response to untreated macrophages (Table-2). This will provide novel insights into how macrophages respond to N. gonorrhoeae infections. This data is part of a pre-publication release.

Project description:Background: There is some evidence demonstrating the effect of psychological interventions in improvements in health biological parameters. To best of our knowledge, no study had addressed the impact of any psychological intervention on extracellular vesicles. In addition, Mindfulness-Based Cognitive Therapy (MBCT) and Emotion Focused Therapy for Cancer Recovery (EFT-CR) in the group have never been explored regarding extracellular vesicles and the effectiveness of these was not compared yet.
Objectives:
1. To explore and compare the effect of MBCT and EFT-CR on biological parameters and psychological variables in distressed people who have had breast, prostate and colorectal cancer;
2. In addition, we will explore the acceptability through recruitment and retention rates of MBCT and EFT-CR in group and evaluate whether these interventions are appropriate for a larger clinical trial.
Methods: The design of this study is a parallel randomized controlled trial. Participants will be randomized into MBCT, EFT-CR or usual care. Outcome measures will be assessed before, at the end of the intervention (8 weeks) and follow-ups (24 and 52 weeks from the baseline moment).
Hypotheses: The researchers expected that both interventions will have an effect on extracellular vesicles and other study biomarkers as well as improvements in psychological outcomes, compared to treatment as usual (TAU) group. Regarding the comparative effectiveness, we did not have evidence to hypothesize which one of the interventions will be superior in both biological (extracellular vesicles) and psychological outcomes.
Contribution for practice: The results of this preliminary study would permit to know if there are benefits of these psychological interventions on changes in extracellular vesicles and on psychological outcomes related to health. In addition, this study will permit to determine the acceptability of conducting a larger randomized controlled trial.

Project description:Previous studies have shown that the circulating miRNA signatures are altered in plasma-derived extracellular vesicles of individuals with type 1 diabetes. These alterations in the miRNA profile could serve as a potential biomarker applicable in clinical practice for monitoring disease status in lactating mothers with type 1 diabetes during the postpartum period. In the present study, we investigate the profiles of extracellular vesicle-derived miRNAs in circulation in a cohort of lactating mothers with and without type 1 diabetes.
