Identification of unique cell type responses in pancreatic islets to stress

ABSTRACT: We single cell sequenced multiplexed primary human islets treated ex vivo with ER and inflammatory chemicals, indexed cell type specific stress responses, found genes to regulate in SC-islets to reduce apoptosis. We conducted multiomic ATAC+RNA sequencing on human islets treated with BFA, DMSO, IL1B+IFNG+TNFa, or PBS

Single nuclei multiomics of human stem cell-derived islets identifies deficiencies in lineage specification

Project description:We profiled the transcritpome and ATAC profiles of human pancreatic islets generated from pluripotent stem cells. Multiomic profiling was also performed on primary human islets and in vivo matured SC-islets for comparision. We catalogued the ATAC associated signatures for each cell types in SC-islets and compared them to their human primiary islet counterparts. In vivo maturation of SC-islets were also compared with in vitro SC-islets. In this study, we identified key regulators associated with islet identity during differentiation and maturation. Gene manipulation of CTCF affects differentiating SC-islet cell fate to enteroendocrine-like lineage. ARID1B knockdown caueses islet cells to present mature signatures. These gene altered SC-islets were also sequenced.

Global microRNA profiling of aTC1-6 and bTC1 before and after treatment with cytokines

Project description:The study sought to determine the global miRNA profiles of mouse pancreatic cell lines aTC1-6 and bTC1 at steady state and after treatment with a cocktail of pro-inflammatory cytokines (IL1b; IFNg and TNFa) for a time course of 24 and 48 hours. Inflammatory cocktail contains IL1b 50 IU/ml; IFNg 1000 IU/ml; TNFa 1000 IU/ml. MicroRNA expression profiles in both cell lines during the different experimental conditions were determined using TaqManM-BM-. Rodent miRNA A+B Cards Set v2.0 (TLDA, Life Technologies). MicroRNA profiles were measured in 3 independent biological replicates. qRT-PCR analysis of microRNAs of aTC1-6 treated with cytokines for 24 and 48 h and of their respective not-treated controls as well as of M-NM-2TC1 cells not treated with cytokines. 180 ng RNA of each sample was reverse transcribed through MegaplexM-bM-^DM-" RT Rodent Primer Pool sets A and B, and preamplified through MegaplexM-bM-^DM-" PreAmp Rodent Primer Pool sets (LifetechnologiesM-bM-^DM-"). Complementary DNA (cDNA) was amplified usingTaqManM-BM-. Rodent miRNA A+B Cards Set v2.0 (Life TechnologiesM-bM-^DM-") with TaqMan Universal PCR Master Mix on an ABI 7900HT Sequence Detection System.

Immune challenged SC-islets first response profiled by single cell transcription analysis after co-culture with human allogeneic PBMCs [scRNA-seq_invitro]

Project description:We performed an in vitro co-culture of allogeneic PBMCs and SC-islet clusters. SC-islet clusters were enriched for β cells (using CD49A magnetic sorting; SC-α still remain at lower numbers) (Veres et al., 2019), dissociated and reaggregated to obtain a more uniform cell count between wells. SC-islets were co-cultured with human allogeneic PBMCs for 24 or 48 hours. As controls [time(t)=0], SC-islets remained in culture without PBMC addition. These samples, in addition to PBMCs alone (t=0), were used for scRNA-seq (Figure 2A).

Herpes simplex virus 1 infection of human brain organoids and pancreatic stem cell-islets drives transcripts associated with Alzheimer’s disease and autoimmune diseases

Project description:Viral infections leading to inflammation have been implicated in several common diseases such as Alzheimer’s disease (AD) and type 1 diabetes (T1D). Of note, herpes simplex virus 1 (HSV-1) has been reported to be associated with AD. We sought to identify the transcriptomic changes due to HSV-1 infection and anti-viral drug (acyclovir, ACV) treatment of HSV-1 infection in dissoci-ated cells from human cerebral organoids (dcOrgs) versus stem cell-derived pancreatic islets (sc-islets) to gain potential biological insights into the relevance of HSV-1-induced inflammation in AD and T1D. We observed that differentially expressed genes (DEGs) in HSV-1-infected sc-islets were enriched for genes associated with several autoimmune diseases, most significantly T1D but also rheumatoid arthritis, psoriasis, Crohn’s disease, and multiple sclerosis, whereas DEGs in HSV-1-infected dcOrgs were exclusively enriched for genes associated with AD. ACV treatment of sc-islets did not rescue transcript expression of autoimmune disease-associated genes. Finally, we identified gene ontology categories that were enriched for DEGs that were in common across, or unique to, viral treatment of dcOrgs and sc-islets, such as categories involved in the transferase complex, mitochondrial and autophagy function. Collectively, this studies pro-vide insight to the molecular effects of inflammation in AD and T1D.

Single-Cell Transcriptome Profiling Reveals β Cell Maturation in Stem Cell-Derived Islets after Transplantation

Project description:SC-β cells and native β cells from cadaveric islets have different transcriptome profiles. In this study, we demonstrate that SC-β cells can acquire mature gene signatures via transplantation in mice for 6 months. MAFA, a marker for mature β cells, is expressed and resulted in significant improvements in insulin release and glucose regulation in diabetic mice.
