Title An integrated multi-omics approach identifies the landscape of interferon-a-mediated responses of human pancreatic beta cells [RNA-seq 2]
Organism Homo sapiens
Experiment type Expression profiling by high throughput sequencing
Summary Proinflammatory cytokines are important mediators of pancreatic beta cell dysfunction and demise in type 1 diabetes (T1D). We presently characterized human beta cell responses to IFNa by combining ATAC-seq, RNA-seq and proteomics assays. The initial beta cell response to IFNa was characterized by major chromatin remodeling, followed by marked changes in transcriptional and translational regulation. IFNa-induced changes in alternative splicing (AS) and first exon usage increased the diversity of transcripts expressed by beta cells. This, combined with changes observed on protein modification/degradation, ER stress and MHC class I, may significantly expand the peptide repertoire presented by beta cells to the immune system. On the other hand, beta cells up-regulated checkpoint proteins, such as PDL1 and HLA-E, that may protect them against the autoimmune assault. Data mining of the present multi-omics analysis led to the identification of two compound classes that revert IFNa effects on human beta cells and may be translated to clinical trials.
Overall design RNA-sequencing of 6 independent experiments of the pancreatic human islets exposed or not to intereron-alpha for 2, 8 and 18h.
