Project description:This SuperSeries is composed of the following subset Series: GSE30721: Profiling proteome-scale antibody responses to M. tuberculosis proteins in sera of macaques infected with M. tuberculosis GSE30722: Profiling proteome-scale antibody responses to M. tuberculosis proteins in TB suspect's sera Refer to individual Series
Project description:microRNA profiles of Exosomes from Pooled NPC Patients serum comparing Control Exosomes from Healthy donors serum Two-condition experiment, Exosomes from Pooled Healthy donors serum vs. Exosomes from Pooled NPC Patients serum. Biological replicates: 1 Exosomes from Pooled Healthy donors serum, 1 Exosomes from Pooled NPC Patients serum,
Project description:Exosomes were isolared from saliva od healthy individuals and head and neck cancer (HNSCC) patients.miRNA profiling of saliva-derived exosomes was perfomred using nCounter SPRINT system. Samples were grouped according to Healthy and Tumor based on their saliva-derived exosomal miRNA profile.
Project description:In order to analyze differences in the proteome composition of blood plasma-derived exosomes in chronic lymphocytic leukemia (CLL) versus healthy donors, mass spectrometry was conducted for whole protein lysates of plasma-derived exosomes. Abundance of proteins was compared via label free quantification.
Project description:Investigation to study mRNA transcripts present in exosomes from M.tb infected cells and how they compare to those derived from uninfected cells. Transcripts were also studied in donor macrophages as controls The gene expression study identified unique transcripts as well as differentially expressed transcripts present in exosomes released from infected macrophages
Project description:Exosomes were isolated from plasma and saliva of healthy individuals and head and neck cancer (HNSCC) patients. miRNA profiling of plasma- and saliva-derived exosomes was performed using nCounter SPRINT system. Diagnostic panels were selected from the exosomal miRNA profile.
Project description:This study examined the miRNA expression level in exosomal derived from the plasma of first episode schizophrenia (FOS) patients and Healthy controls (HC), and explored the the potential of exosomes as biomarkers for schizophrenia.

Project description:We hypothesized that miRNAs in the bone maroow mesenchymal stem cells (BM-MSC)-derived exosomes contributed to the phenotype change of breast cancer cells through exosome transfer. We analyzed the miRNA expression signature in BM-MSC-derived exosomes. We compared the miRNA expression levels in exosomes between BM-MSCs and adult fibroblasts (as a control). In this study, miRNA expression including in bone-marrow mesenchymal cell (BM-MSC)-derived exosomes was examined, and compared with that of exosomes derived from adult fibroblast cells or the BM-MSC cells. In addition, miRNA expression of BM-MSC exosomes was also compared with that of breast cancer cells with or without cancer stem cell marker.
Project description:In chronic lymphocytic leukemia (CLL), monocytes and macrophages are skewed toward protumorigenic phenotypes, including the release of tumor-supportive cytokines and the expression of immunosuppressive molecules such as programmed cell death 1 ligand 1 (PD-L1). To understand the mechanism driving protumorigenic skewing in CLL, we evaluated the role of tumor cell–derived exosomes in the cross-talk with monocytes. We carried out RNA sequencing and proteome analyses of CLL-derived exosomes and identified noncoding Y RNA hY4 as a highly abundant RNA species that is enriched in exosomes from plasma of CLL patients compared with healthy donor samples. Transfer of CLL-derived exosomes or hY4 alone to monocytes resulted in key CLL-associated phenotypes, including the release of cytokines, such as C-C motif chemokine ligand 2 (CCL2), CCL4, and interleukin-6, and the expression of PD-L1. These responses were abolished in Toll-like receptor 7 (TLR7)–deficient monocytes, suggesting exosomal hY4 as a driver of TLR7 signaling. Pharmacologic inhibition of endosomal TLR signaling resulted in a substantially reduced activation of monocytes in vitro and attenuated CLL development in vivo. Our results indicate that exosome-mediated transfer of noncoding RNAs to monocytes contributes to cancer-related inflammation and concurrent immune escape via PD-L1 expression.
