Mice that globally over-express the transcription factor, Fos-related antigen-2 (Fra-2), develop extensive pulmonary fibrosis and pulmonary vascular remodeling. To determine if these phenotypes are a consequence of ectopic Fra-2 expression in vascular smooth muscle cells and myofibroblasts, we generated mice that over-express Fra-2 specifically in these cells types (α-SMA-rtTA; tetO-Fra-2). Surprisingly, these mice did not develop vascular remodeling or pulmonary fibrosis, but developed a spontaneous emphysema-like phenotype characterized by alveolar enlargement...

OBJECTIVE: Infusion of angiotensin II (Ang II) induces extracellular matrix remodeling and inflammation resulting in abdominal aortic aneurysms (AAAs) in normolipidemic mice. Although Ang II activates mesenchymal cells in the media and adventitia to become fibrogenic, the sentinel role of this mesenchymal population in modulating the inflammatory response and aneurysms is not known. We test the hypothesis that these fibrogenic mesenchymal cells play a critical role in Ang II-induced aortic wall vascular inflammation and AAA formation...

BACKGROUND: Sjögren's syndrome (SS) shares many clinical and pathological similarities with systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). These autoimmune diseases mostly affect women. In this study, concept profile analysis (CPA) and gene expression meta-analysis were used to identify genes potentially involved in SS pathogenesis. METHODS: Human genes associated with SS, SLE, and RA were identified using the CPA tool, Anni 2.1. The differential mRNA expression of genes common to SS and SLE (SS-SLE) was determined in female peripheral blood mononuclear cells (PBMCs) using NCBI-GEO2R...

Takayasu arteritis (TAK) is a vasculitis of the large arteries. The arterial wall, target of the immune reaction, is composed of vascular dendritic cells, endothelial cells, vascular smooth muscle cells and fibroblasts, which engage in an interaction with T cells and macrophages to, ultimately, cause luminal stenosis or aneurysmal wall damage of the vessel. A multitude of cytokines have been identified to increase in case of TAK and to be linked to disease activity. A better understanding of the physiopathological pathways and mechanisms involved, might enable a more tailored therapeutic approach in TAK...

Monocytes infiltrating scar tissue are predominantly viewed as progenitor cells. Here, we show that tissue CCR2(+) monocytes possess specific immunosuppressive and pro-fibrotic functions. CCR2(+) monocytic cells are acutely recruited to the lung before the onset of silica-induced fibrosis in mice. These tissue monocytes are defined as monocytic-Myeloid-Derived Suppressor Cells (M-MDSC) because they significantly suppress T lymphocyte proliferation in vitro. M-MDSC collected from silica-treated mice also express TGF-β1, which stimulates lung fibroblasts to release TIMP-1, an inhibitor of metalloproteinase collagenolytic activity...

Tumor development is influenced by stromal cells in aspects including invasion, growth, angiogenesis, and metastasis. Activated fibroblasts are one group of stromal cells involved in cancer metastasis, and one source of activated fibroblasts is endothelial to mesenchymal transformation (EndMT). EndMT begins when the endothelial cells delaminate from the cell monolayer, lose cell-cell contacts, lose endothelial markers such as vascular endothelial-cadherin (VE-cadherin), gain mesenchymal markers like alpha-smooth muscle actin (α-SMA), and acquire mesenchymal cell-like properties...

TGF-β1, 2 and 3 cytokines are involved in many cellular processes including cell proliferation, differentiation, migration and survival. Whereas TGF-β2 and 3 play important roles in embryonic development, TGF-β1 is mostly implicated in controlling immune responses after birth. The production of TGF-β1 is a tightly regulated process, occurring mostly at a post-translational level. Virtually all cells produce the latent, inactive form of TGF-β1. In latent TGF-β1, the mature TGF-β1 dimer is non-covalently associated to the Latency Associated Peptide, or LAP, which prevents binding to the TGF-β1 receptor...

Proepicardium (PE) cells generate cardiac fibroblasts, smooth muscle cells (SMCs) and endothelial cells that form coronary arteries. T-box18 (Tbx18) is a well-known marker of PE cells and epicardium. We examined whether Tbx18-positive cells differentiated from murine embryonic stem (ES) cells serve as PE progenitors to give rise to vascular SMCs and fibroblasts. To collect Tbx18-positive cells, we established Tbx18-EGFP knock-in mouse ES cells using the CRISPR/Cas9 system. We harvested the Tbx18-EGFP-positive cells on day 8, 10 and 14 after the initiation of differentiation; Tbx18 mRNA was enriched on day 8 to 14 and Snai2 mRNA was enriched on day 8 and 10, indicating successful collection of Tbx18-positive cells...

Dengue virus (DENV) regulates sphingosine kinase (SK)-1 activity and chemical inhibition of SK1 reduces DENV infection. In primary murine embryonic fibroblasts (pMEFs) lacking SK1 however, DENV infection is enhanced and this is associated with induction of normal levels of interferon beta (IFN-β) but reduced levels of IFN-stimulated genes (ISGs). We have further investigated this link between SK1 and type I IFN responses. DENV infection downregulates cell-surface IFN-alpha receptor (IFNAR)1 in both wild-type (WT) and SK1(-)(/-) pMEF, but, consistent with poor ISG responses, shows reduced induction of phosphorylated (p)-STAT1 and key IFN regulatory factors (IRF)1 and -7 in SK1(-/-) pMEF...

The brain and skull represent a complex arrangement of integrated anatomical structures composed of various cell and tissue types that maintain structural and functional association throughout development. Morphological integration, a concept developed in vertebrate morphology and evolutionary biology, describes the coordinated variation of functionally and developmentally related traits of organisms. Syndromic craniosynostosis is characterized by distinctive changes in skull morphology and perceptible, though less well studied, changes in brain structure and morphology...

Fibrosis is the result of dysregulated tissue regeneration and is characterized by excessive accumulation of matrix proteins that become detrimental to tissue function. In Crohn's disease, this manifests itself as recurrent gastrointestinal strictures for which there is no effective therapy beyond surgical intervention. Using a model of infection-induced chronic gut inflammation, we show that Rora-deficient mice are protected from fibrosis; infected intestinal tissues display diminished pathology, attenuated collagen deposition, and reduced fibroblast accumulation...

Epidemiological evidence implicates excess adipose tissue in increasing cancer risk. Despite a steeply rising global prevalence of obesity, how adiposity contributes to transformation (stage a non-tumorigenic cell undergoes to become malignant) is unknown. To determine the factors in adipose tissue that stimulate transformation, we used a novel ex vivo system of visceral adipose tissue (VAT)-condition medium-stimulated epithelial cell growth in soft agar. To extend this system in vivo, we used a murine lipectomy model of ultraviolet light B-induced, VAT-promoted skin tumor formation...

Implant failures are primarily related to bacterial infections and inflammation. Nanocoating of implant devices with organic molecules is a method used for improving their integration into host tissues and limiting inflammation. Bioengineered plant-derived rhamnogalacturonan-Is (RG-Is) from pectins improve tissue regeneration and exhibit anti-inflammatory properties. Therefore, the aim of this study is to evaluate the in vitro effect of RG-I nanocoating on human gingival primary fibroblast (HGF) activity and proinflammatory response following Porphyromonas gingivalis (P...

Alopecia areata (AA) is a common autoimmune disorder affecting millions of people worldwide, which manifests as a sudden, non-scarring hair loss. The expression of a pro-inflammatory cytokine, interferon-gamma (INF-γ), has been well established to be involved in the development of AA. As IFN-γ and other cytokines are also known to up-regulate programmed cell death ligand 1 and 2 (PD-L1 and PD-L2), which both negatively control immune responses, we asked whether or not a high number of infiltrated T cells, seen in AA lesions, can modulate the expression of PD-L1 and PD-L2 in skin cells...

The apicomplexan parasite Toxoplasma gondii infects various cell types in avian and mammalian hosts including humans. Infection of immunocompetent hosts is mostly asymptomatic or benign, but leads to development of largely dormant bradyzoites that persist predominantly within neurons and muscle cells. Here we have analyzed the impact of the host cell type on the co-transcriptomes of host and parasite using high-throughput RNA sequencing. Murine cortical neurons and astrocytes, skeletal muscle cells (SkMCs) and fibroblasts differed by more than 16,200 differentially expressed genes (DEGs) before and after infection with T...

Aneuploidy, a hallmark of cancer cells, poses an appealing opportunity for cancer treatment and prevention strategies. Using a cell-based screen to identify small molecules that could selectively kill aneuploid cells, we identified the compound N-[2-hydroxy-1-(4-morpholinylmethyl)-2-phenylethyl]-decanamide monohydrochloride (DL-PDMP), an antagonist of UDP-glucose ceramide glucosyltransferase. DL-PDMP selectively inhibited proliferation of aneuploid primary mouse embryonic fibroblasts and aneuploid colorectal cancer cells...
