Role of tRNA-derived fragments in the cross-talk between immune cells and beta cells during type 1 diabetes pathogenesis (EV-treated)

Project description:Transfer RNAs (tRNAs) play a central and well recognized role in protein synthesis. Recent studies revealed that these molecules can be cleaved to generate tRNA fragments (tRFs) with regulatory functions. Here, we studied the contribution of tRFs to pancreatic β-cell loss during the initial phases of type 1 diabetes (T1D), an autoimmune disorder characterized by the invation of immune cells in the pancreas and progressive loss of insulin-secreting cells. Small RNA-profiling showed that the pool of tRFs present in pancreatic β-cells is altered in non-obese diabetic (NOD) mice, a mouse model used to study T1D. We found that part of these changes is triggered by the exposure of β-cells to proinflammatory cytokines released during the autoimmune reaction while others result from the direct transfer of tRFs from autoreactive T lymphocytes to insulin-secreting cells via extracellular vesicles. Indeed, using an RNA-tagging approach, we could demonstrate that a group of tRFs are transferred in vivo in from CD4+CD25- T lymphocytes to pancreatic β-cells, upon T cell adoptive transfer in NOD scid mice. Morevoer, the up-regulation of selected tRFs associated with the autoimmune reaction triggers β-cell apoptosis and gene expression changes that affect the immune regulatory capacity of β-cells. Our data point to tRFs as novel players in type 1 diabetes and potentially in other autoimmune disorders.

Unravelling tRNA Fragments in DENV Pathogenesis: Insights from RNA Sequencing

Project description:tRNA-derived small RNA including tRNA-derived fragments (tRFs) and tRNA halves (tiRNAs) plays significant roles in the various molecular mechanisms that underlie certain human diseases. of the generation of tRFs/tiRNAs and their potential roles during Dengue virus (DENV) infection is not yet known. Here, we have performed small RNA sequencing to identify the generation and alterations in tRF expression profiles of DENV infected Huh7 cells. Our results suggest that 733 tiRNAs/tRFs were found to be differentially expressed during DENV infection. Interestingly, 3’tRF population were found to be upregulated and i-tRF population were found to be downregulated. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) were performed to analyze the impact of differentially expressed tRFs on DENV pathogenesis. Our results suggest the significant involvement in transcriptional regulation via RNA polymerase II promoter and metabolic pathways. Overall, our study contributes significantly to our understanding of the roles played by tRFs in the complex dynamics of DENV infection.

Differential Expression Spectrum of tRNA fragments in Alzheimer's Disease

Project description:We report the profiling of tRNA fragments from the temporal cortex of controls and late-stage Alzheimer's disease subjects. We show tRNA fragments expression changes between the two groups. Four upregulatedtRNA fragments in the results of Real Time-qPCR were consistent with the small RNA microarray:5'tRF_GluCTC, 5'tRF_GluTTC, 5'tRF_GlyGCC, 5'tRF_GlyCCC
