Project description:To assess the effect of Furin ablation on TEC development and heterogeneity, we detected the transcriptional profiles of 2-week-old WT and Furin KO TECs using single-cell RNA-seq. Employing an unsupervised graph-based clustering strategy, 20 clusters of TECs and 5 clusters of non-TEC contaminants were identified. After removing contaminants, 4301 WT TECs and 4086 Furin KO TECs were obtained. UMAP visualization revealed that the proportion of mTECs decreased significantly and the proportion of cTECs increased significantly in TEC-specific Furin knockout mice in comparison with WT mice. Further analysis showed that Furin ablation did not affect the proportion of mTEC I, II and III subsets, but reduced the proportion of mTEC IV subsets markedly.

Project description:We created furin KO cells in three colorectal cancer cell lines (DLD1, HCA7 and HT29) using CRISPR-Cas9 genome editing. And then we performed RNA-Seq analysis in furin KO colorectal cancer cells to identify potential effect of furin on gene expression patterns in DLD1, HCA7 and HT29 cells.

Project description:The proprotein convertase enzyme FURIN processes immature pro-proteins into functional end- products. FURIN is upregulated in activated immune cells and it regulates T-cell dependent peripheral tolerance and the Th1/Th2 balance. FURIN also promotes the infectivity of pathogens by activating bacterial toxins and by processing viral proteins. Here, we evaluated the role of FURIN in LysM+ myeloid cells in vivo. Mice with a conditional deletion of FURIN in their myeloid cells (LysMCre-fur(fl/fl)) were healthy and showed unchanged proportions of neutrophils and macrophages. Instead, LysMCre-fur(fl/fl) mice had elevated serum IL-1β levels and reduced numbers of splenocytes. An LPS injection resulted in accelerated mortality, elevated serum pro-inflammatory cytokines and upregulated numbers of pro-inflammatory macrophages. A genome-wide gene expression analysis revealed the overexpression of several pro-inflammatory genes in resting FURIN-deficient macrophages. Moreover, FURIN inhibited Nos2 and promoted the expression of Arg1, which implies that FURIN regulates the M1/M2-type macrophage balance. FURIN was required for the normal production of the bioactive TGF-β1 cytokine, but it inhibited the maturation of the inflammation-provoking TACE and Caspase-1 enzymes. In conclusion, FURIN has an anti-inflammatory function in LysM+ myeloid cells in vivo.

Project description:Analysis of T-cells lacking the proprotein convertase furin. Proprotein convertases promote the proteolytic maturation of proproteins. Furin is induced in activated T-cells. Results provide insight into the function of furin in T-cells. CD4+CD62L+CD44- naive, CD4+CD62L-CD44+ memory and CD4+CD25+FoxP3+ regulatory T cells were isolated from Fur flox/flox and CD4 cre Fur flox/flox mice. Naive T cells were activated via TCR. Total RNA was extracted from all cells and hybridized to Affymetrix microarrays.

Project description:Purpose: FURIN is a member of the proprotein convertase subtilisin/kexin (PCSK) family of serine endoproteases important in converting immature proproteins into their functional form. While FURIN is important in various aspects of the immune response such as in CD4+ T cells, FURIN´s role in CD8+ T cells is unclear. Here, we isolated naive CD8+ T cells from conditional T cell specific Furin KO (Cd4-Cre-Furinflox/flox) and WT (Furinflox/flox) mice and studied the genome-wide gene expression pattern upon in vitro anti-CD3/anti-CD28 activation (plate-bound, 5µg/ml each) using RNA sequencing. We also used recombinant TGFB1 (0.5ng/ml) or IL12 (10ng/ml) in the same experimental setting to study their impact on the CD8+ T cell transcriptome. Methods: Total RNA was isolated from the stimulated CD8+ T cells and the RNA-sequencing data was produced by the Functional Genomics Unit of the HiLIFE Genome Analysis Infrastructure (University of Helsinki, Helsinki, Finland) using Illumina NextSeq High Output 1x75 bp. Data processing pipeline was built on Snakemake wrappers, and used STAR to quantify features from quality and adapter trimmed reads in gene level. Prior the normalisation and differential gene expression analysis with DESeq2, the matrix of raw gene counts was prefiltered to keep only rows that have at least 10 reads in total. Result tables were annotated with biomaRt. Results: Snakemake preprocessing pipeline measured 55573 genes against GRCm38, ENSEMBL release 97. 17714 of them was used for statistical testing. Full result tables for each treatment were ranked by p-value and the normalized DESeq2 abundances in samples were included. The genes with BH-adjusted p-value <0.05 was considered differentially expressed. Conclusions: Our study revealed that the abscence of FURIN influences the expression of several genes in activated CD8+ T cells. Additionally, although FURIN-deficient CD8+ T cells can respond to exogenous TGFB1 and IL12, administrating these cytokines further increases the number of differentially expressed genes between Furin KO and WT CD8+ T cells.
