Single-cell RNA-Seq of entire ventricles of C57BL/6J and B6.Rag2del mice after myocardial infarction

ABSTRACT: We compared the cellular and molecular outcome following permanent LAD ligation in wildtype and T- and B cell deficient Rag2del mice. Our results demonstrate that the significant changes in the cardiac immune response following myocardial infarction (MI). 8-12 weeks old, male and female C57BL/6J mice (Charles River, Wilmington, MA, USA) and B6.Rag2del mice (Jackson laboratory, Bar Harbor, ME, USA) were used for this study. Seven days after MI, entire mouse ventricles were isolated and enzymatically digested. Cells were then labelled with CD45 magnetic beads (Miltenyi Biotec, Germany) and positively enriched using the AutoMACS instrument (Miltenyi Biotec, Germany). Viable macrophages/monocytes (CD45+CD11b+CD11c-DAPI-Lactadherinlo), dendritic cells (CD45+CD11b+CD11c+ DAPI-Lactadherinlo), and NK cells (CD45+CD11b-CD11c+NK1.1+ DAPI-Lactadherinlo) were then sorted on the BD FACSAriaTM IIIu (Becton Dickinson, Franklin Lakes, NJ, USA) roughly in a 1:1:1 ratio into DMEM containing 10% FCS before processing for 10× Genomics single-cell RNA sequencing (scRNA-Seq). Libraries for scRNA-Seq were constructed according to the 10× Genomics protocol using the GemCode Single-Cell 3′ Gel Bead and Library V3 Kit. Quality of amplified cDNA and final libraries were evaluated on the 2100 Bioanalyzer instrument (Agilent) using a High Sensitivity NGS Analysis Kit (Advanced Analytical). Subsequent sequencing was conducted on the HighSeq4000 Sequencing System using the HiSeq SBS and HiSeq PE Cluster Kit V4 (all Illumina, San Die-go, CA. USA).

RNA-seq of islet, FACS- sorted CD45+Ly6C-CD11B+CD11C+F4/80+ cells from C57bl6/J male mice that were treated with low dose streptozotocin (STZ) or acetate buffer

Project description:The experiment was designed to obtain a broader unbiased view of the changes in islet macrophages following low dose STZ challenge. Mice were purchased from Jackson Laboratory (Bar Harbor, ME). 16-20-week-old C57BL/6J males were given 30 mg/kg STZ or acetate buffer (control) i.p. (intraperitoneal injection) for 5 consecutive days. Following the first STZ or buffer injection mice were sacrificed on day 14 and islets were isolated by collagenase digestion. Freshly isolated islets were dispersed in 0.02% Trypsin-EDTA for 3 minutes followed by up to 1 minute of pipetting under a stereomicroscope to obtain a single cell solution. Islet media was added to stop the reaction. Islets from 10 mice were pooled per sample (N). Dispersed islets were washed with FACS buffer (1% heat inactivated FBS, 1 mM EDTA, 11 mM glucose in PBS). Cells were kept on ice and pre-incubated with Fc Block (1:100) for 5 minutes, followed by 30 min incubation with CD45-eFluor 450 (1:250; clone 30-F11), Ly-6C-APC (1:1,200; clone HK1.4), CD11b-PE (1:1,200; clone M1/700, F4/80-FITC (1:150; clone BM8), CD11c-PECy7 (1:150; clone N418), and the viability dye 7AAD (1:2,000). Unstained, single stains, and fluorescence minus one controls were used for setting gates and compensation. Viable, single CD45+Ly6c-Cd11b+Cd11c+F4/80+ cells were sorted using a BD FACS Aria IIu directly into lysis buffer, and the RNeasy Plus Micro Kit from Qiagen was used to isolate total RNA. Total RNA quality control quantification was performed using an Agilent 2100 Bioanalyzer. All RNA samples had an RNA integrity number (RIN) ≥9.1. The NeoPrep Library Prep System from Ilumina was used for library preparation followed by sequencing using standard Illumina methods and Ilumina NextSeq500.

Expression profiling of small intestine lamina propria dendritic cells

Project description:Dendritic cells play a vital role in initiating robust immunity against pathogens as well as maintaining immunological tolerance to self antigens, food antigens and intestinal commensals. However, the intracellular signaling networks that program DCs to become tolerogenic are largely unknown. To address this, we analyzed gene expression profiles using microarray analysis of purified intestinal lamina propria DCs (CD11c+ CD11b+ DCs and CD11c+ CD11b- DCs) from mice. Keywords: Lamina propria, DCs, cell type comparison We sought to determine the expression profile of small intestine lamina propria CD11c+ cells. RNA was extracted from DCs sorted from mouse small intestine (CD11c+CD11b- and CD11c+CD11b+ cells) and hybridized on Affymetrix microarrays.

Comparison of splenic and small intestine lamina propria dendritic cells

Project description:This SuperSeries is composed of the following subset Series: GSE22127: Expression profiling of small intestine lamina propria dendritic cells GSE22128: Expression profiling of splenic dendritic cells Dendritic cells play a vital role in initiating robust immunity against pathogens as well as maintaining immunological tolerance to self antigens, food antigens and intestinal commensals. However, the intracellular signaling networks that program DCs to become tolerogenic are largely unknown. To address this, we analyzed gene expression profiles using microarray analysis of purified intestinal lamina propria DCs (CD11c+ CD11b+ DCs and CD11c+ CD11b- DCs) and compared it to splenic DCs (CD11c+ DC), from mice. We sought to determine the unique genetic profile of small intestine lamina propria CD11c+ cells compared to splenic CD11c+ cells. We performed a meta-analysis using the expression profiles of Intestinal lamina propria CD11c+ CD11b+ DCs (GSM550122), Intestinal lamina propria CD11c+ CD11b- DCs (GSM550121) and Splenic CD11c+ DCs (GSM550126). This study combined and re-normalized the microarray data from GSE22127 and GSE22128 studies. Refer to individual Series for additional details

Colony stimulating factor (CSF1) treatment of kidneys that have undergone ischemia reperfusion injury

Project description:Mice were subjected to renal artery clamps to induce ischemia/reperfusion injury to the kidney. 3 days post surgery mice were injected with CSF1 or PBS daily for a further 3 days. Mice were sacrificed 5 and 7 days post surgey and the kidney was removed and homogenised into single cell suspensions. Cells were selected on their expression of CD45, CD11b markers and the lack of CD11c. These cells were then subjected to microarray analyses to determine the global gene expresssion profiles of mice with and without treatment.
