Partial CRISPR/Cas9 IL1R1 & IFNGR1 Knock-Down Improves β-cell Survival And Function Under Cytokine-Induced Inflammation

Daems Caroline , Vanderroost Juliette , Sokal Etienne , Lysy Philippe

Type 1 diabetes (T1D) is a chronic disease characterized by the autoimmune destruction of pancreatic β cells. This destruction is mediated by lymphocytes T helper and cytotoxic, and by the action of the pro-inflammatory cytokines IL1β, IFNγ and TNFa inside the islets of Langerhans. We propose a new approach to alleviate islet inflammation by targeting pro-inflammatory cytokine receptors. Our hypothesis is that the downregulation of inflammatory pathways ma...

Presently, the autoimmune character of T1D is challenged, but it is indisputable that inflammation plays a key role in its development. We hypothesized that glucotoxicity could contribute to β-cell mass destruction through maintenance of inflammation. Here, we aimed to evaluate, after diabetes onset, the potential of empagliflozin (EMPA) to protect β-cell mass against glucotoxicity, in monotherapy or in association with GABA, tested for its potential to increas...

Background: Pancreatic epithelial cells represent an attractive cell source for replacement therapy of type 1 diabetes. Previously, we designed a protocol for expansion of human pancreatic duct-derived cells (HDDCs) and showed their β-cell engineering potential.Objective and hypotheses: In this study, we reprogrammed HDDCs into β-cell-like lineage by over-expressing mRNAs of key pancreatic transcription factors (TFs).Meth...
