(Submitter supplied) we studied the role of exosomes isolated from M.tb infected macrophages in modulating the macrophage response to IFN-γ. Nimblegen microarray gene expression studies were used to compare the suppression of IFN-γ inducible genes by exosomes relative to the virulent strain of M.tuberculosis. Overall our study suggest that exosomes, as carriers of M.tb pathogen associated molecular patterns (PAMPs), may provide a mechanistic link by which M.tb may exert its suppression of host immune response beyond the infected cell, and implies a physiological role for exosomes in immune surveillance of TB.

(Submitter supplied) Bone marrow (BM) cells were obtained by flushing the long bones of 8-week old C57BL/6 mice. BM cells were then were plated in macrophage SFM medium (Life Technologies) supplemented with penicillin-streptomycin and CSF-1 (Peprotech, 100 ng/ml) and cultured for one week to allow macrophage differentiation. BMDMs were polarized by adding IL-4 to the medium (40 ng/ml, Peprotech) for 72h or left untreated.

(Submitter supplied) Exosomes are cell-derived vesicles that were found in many biological fluids such as blood, urine, and cultured medium. Exosomes are small vesicles (approximately 100nm in diameter) that contain many functional molecules like cytokines, receptors and regulating RNAs. In this study, we found that uMSC-derived exosomes accelerates wound healing and reduce myoblast formation in vivo. In vitro study showed uMSC-exosomes specific microRNAs take major roles in inhibiting myoblast differentiation of fibroblast. more...

(Submitter supplied) Milk is an essential source of nutrients to all mammalian offspring, and is rich in a wide variety of immunological components. Recently reported miRNAs that are present in breast milk and are selectively packaged into the exosomes, a type of membrane vesicles, secreted by most cell types. These exosomal miRNAs could be actively delivered into recipient cells, and play a key role in the regulation of innate and adaptive immunity. more...

(Submitter supplied) Human alveolar macrophages (HAM) are primary bacterial niche and immune response cells during Mycobacterium tuberculosis (M.tb) infection, and human blood monocyte-derived macrophages (MDM) are a model for investigating M.tb-macrophage interactions. Here, we use a targeted RNA-Seq method to measure transcriptome-wide changes in RNA expression patterns of freshly obtained HAM (used within 6 h) and 6 day cultured MDM upon M.tb infection over time (2, 24 and 72 h), in both uninfected and infected cells from three donors each. more...

(Submitter supplied) Primary human monocytes were isolated from four healthy human blood donors. Monocytes were isolated from PBMC buffy coats using plastic adherence for 4 hours. Monocytes were allowed to differentiate into macrophages over a period of 1 week. Macrophages from each of the 4 donors were split into two groups - uninfected and infected with Mycobacterium tuberculosis (Mtb). Cells in the infection group were infected with Mtb for 48 hours at a multiplicity of infection (MOI) of 10. more...

Monocytes were differentiated into macrophages, infected with virulent Mycobacterium tuberculosis (Mtb), strain H37Rv, for 24 or 48 hours, at a multiplicity of infection of 5 or 10. Following infection, infected cells and time-matched uninfected controls were harvested, total RNA including small RNAs was isolated and used for next-generation small RNA sequencing. more...

(Submitter supplied) We investigated placenta-specific miRNA miR-517a (miR-517a-3p) functions in Jurkat cells. For this purpose, we identified candidate target mRNAs of the placenta-specific miRNAs using DNA microarray analysis. Transfection of Jurkat cells with miR-517a significantly downregulated 123 genes. Among the 123 genes identified, we searched for potential direct targets of miR-517a using the online software MicroCosm Targets. more...

(Submitter supplied) We have reported that microRNAs are present in human, bovine, and rat milk whey. Milk whey miRNAs were resistant to acidic condition and to RNase. Thus, milk miRNAs were thought to be present packaged into membrane vesicles like exosome. However, body fluid miRNAs have been reported that there are in different forms. To clarify which miRNAs species are exist in exosome and which species are exist in another form, we used bovine raw milk and purified total RNA from exosome fraction and ultracentrifugated supernatant fraction, and analyzed by miRNA microarray.

(Submitter supplied) Exosomes are small extracellular vesicles that carry heterogeneous cargo, including RNA, between cells. Increasing evidence suggests that exosomes are important mediators of intercellular communication and biomarkers of disease. Despite this, the variability of exosomal RNA between individuals has not been well quantified. To assess this variability, we sequenced the small RNA of cells and exosomes from a 17-member family. more...
