Rat insulin-producing INS-1E exposed to cytokines IL-1β and IFN-γ

ABSTRACT: In the context of T1 Diabetes, pro-inflammatory cytokines IL-1β and IFN-γ are known to contribute to β-cell apoptosis; The measurement of mRNA expression following β-cell exposure to these cytokines gives a picture of the changes in gene expression characterizing the path to β-cell dysfunction and death. INS1 cell lines were cultured in medium with or without IL-1β and IFN-γ. The samples were collected at various time points for profiling with Affymetrix Rat ST arrays. These experiments were performed on two separate occasions.

Human islets exposed to cytokines IL-1β and IFN-γ

Project description:In the context of T1 Diabetes, pro-inflammatory cytokines IL-1β and IFN-γ are known to contribute to β-cell apoptosis; The measurement of mRNA expression following β-cell exposure to these cytokines gives a picture of the changes in gene expression characterizing the path to β-cell dysfunction and death. Human islets were isolated and exposed (or not) to IL-1β and IFN-γ. The samples were collected at various time points for profiling with Affymetrix arrays. These measurements were performed three times.

The human pancreatic islet transcriptome: impact of pro-inflammatory cytokines

Project description:We have used RNA-seq to identify transcripts, including splice variants, expressed in human islets of Langerhans under control condition or following exposure to the pro-inflammatory cytokines interleukin-1β (IL-1β) and interferon-γ (IFN-γ). A total of 29,776 transcripts were identified as expressed in human islets. Expression of around 20% of these transcripts was modified by pro-inflammatory cytokines, including apoptosis- and inflammation-related genes. Chemokines were among the transcripts most modified by cytokines. Interestingly, 35% of the genes expressed in human islets undergo alternative splicing as annotated in RefSeq, and cytokines caused substantial changes in spliced transcripts. Nova1, previously considered a brain-specific regulator of mRNA splicing, is expressed in islets. 25/41 of the candidate genes for type 1 diabetes are expressed in islets, and cytokines modified expression of several of these transcripts. 5 human islet of Langerhans preparations examined under 2 conditions (control and cytokine treatment)

Transcription profiling of rat insulinoma-beta (INS-1E) cells exposed to the cytokines IL-1-beta and IFN-gamma for six different lengths of time and with or without the inducible NO synthase blocker NMA

Project description:Locally released cytokines contribute to beta cell dysfunction and apoptosis in Type 1 diabetes. In vitro exposure of insulin producing INS-1E cells to the cytokines interleukin (IL)-1beta + interferon (IFN) gamma leads to a significant increase in apoptosis. To characterize the genetic networks implicated in beta cell dysfunction and apoptosis and its dependence on nitric oxide (NO) production, we performed a time course analysis using the Affymetrix RG U34A microarry. INS-1E cells were exposed in duplicate to IL-1beta + IFN-gamma for six different time points (1, 2, 4, 8, 12, and 24 h) with or without the inducible NO synthase blocker.

Single-cell RNA-sequencing of mouse islets exposed to proinflammatory cytokines

Project description:Exposure to proinflammatory cytokines is believed to contribute to pancreatic β-cells during diabetes development. While some cytokine-mediated changes in islet gene expression are known, the heterogeneity of the response is not well-understood. Following 6 hour treatment with interleukin-1 beta (IL-1β) and interferon-gamma (IFN-γ) alone or together, mouse islets were subjected to single-cell RNA-sequencing (scRNA-seq). Inducible nitric oxide synthase (iNOS) mRNA (Nos2), antiviral genes, and immune-associated genes were induced in a subset of β-cells in response to both cytokines, while IL-1β alone activated only antiviral genes. Subsets of α- and δ-cells expressed Nos2 and exhibited similar gene expression changes as β-cells, including induction of antiviral genes and repression of identity genes. Finally, cytokine-responsiveness was inversely correlated with expression of genes encoding heat shock proteins. Our findings show that all endocrine cell types respond to cytokines, IL-1β induces the expression of protective genes in β-cells, and cellular stress gene expression is associated with an inhibition in cytokine signaling.

Single-cell RNA-sequencing of mouse islets exposed to proinflammatory cytokines [18hrs]
