Integrin avb5 heterodimer is a specific marker of human pancreatic beta cells

Project description:The identification of cell surface markers specific to pancreatic beta cells is important for both the study of islet biology and for investigating the pathophysiology of diseases in which this cell type is lost or damaged. Following analysis of publicly available single-cell RNAseq data, we identified specific integrin subunits, integrin av and integrin b5, that were expressed in beta cells. Flow cytometry analysis showed that the vast majority of islet cells expressed some level of both the av and b5 subunits. Using our analysis of single-cell sequencing data as a guide, we isolated populations expressing both subunits from isolated human islets and subjected these to bulk RNAseq analysis. This analysis suggested that the avlob5lo population was enriched for endocrine cell types including alpha, delta and gamma cells, whilst the avhib5hi population was enriched for pericytes and stellate cells . Interestingly, the av+b5neg reference population appeared to be enriched for myeloid cells. This finding was further elaborated using immunofluorescence analysis of histological sections derived from donor human pancreas. Despite the broad expression of specific integrin subunits, we found that expression of integrin avb5 heterodimers was restricted to beta cells and that this complex persisted in islet remnants of some type 1 diabetic individuals from which insulin expression had been lost. This study identifies avb5 heterodimers as a novel cell surface marker of human pancreatic beta cells, a finding that will aid in the identification and characterisation of this important cell type.

Integrin beta-1 (Itgb1) in profibrotic myofibroblasts

Project description:Fibrosis due to extracellular matrix (ECM) secretion from myofibroblasts complicates many chronic liver diseases causing scarring and organ failure. Integrin-dependent interaction with scar ECM promotes profibrotic features. This microarray study was performed to clarify the role of integrin beta-1 (Itgb1) in profibrotic myofibroblasts.

Cre-mediated deletion of b1 integrin in pancreatic b-cells

Project description:In this study, we investigated the function of beta integrins in developing islet beta-cells by targeting the deletion of exon 3 of the B1 integrin gene using a Cre-lox approach. Our results demonstrate that this class of integrin receptors is critically important for proper beta cell expansion during development

Integrin alpha-V drives pancreatic adenocarcinoma progression due to activation of TGF-β

Project description:In a previous study by our group, it could be shown that peritoneal selectins mediate the peritoneal spread of pancreatic ductal adenocarcinoma (PDA). In the absence of selectins, Integrin alpha-V (ITGAV) is upregulated in the remaining tumor spots. To study the relevance of ITGAV for PDA’s progression, a knockdown of ITGAV was generated using a shRNA-mediated approach in two PDA cell lines.

Analysis of human myeloma cell lines expressing beta 3 integrin

Project description:The aim of these experiments was designed to compare gene expression in human myeloma cell lines expressing beta 3 integrin vs counterpart cell lines that do not express beta 3 integrin. Keywords: Gene expression,cell lines, siRNA Phenotype characterization of both primary and cultured myeloma plasma cells was assessed by flow cytometry (FACScanto, Becton Dickinson, San Jose, CA) using a panel of MoAbs or antisera to the following markers: CD138, CD38, CD56, k/l chains, CD20, CD44, CD54, alphav and beta3 chains. The microarray analysis was performed on: myeloma bone resorbing cell lines alphav-beta3 positive and the same cell line silenced for the integrins; myeloma non bone resorbing cell lines negative for the expression of avb3.
