The anti-fibrosis effect of iguratimod on skin tissues of systemic sclerosis patients

ABSTRACT: To evaluate the possibility of iguratimod working on SSc patients in clinical practice, we collected skin biopsies from three early SSc patients. Three grafts were divided equally into two irradiated nude mice and treated with iguratimod or vehicle solution subcutaneously for five weeks. Total RNA from cultured fibroblasts or xenografts were extracted by TRIzol.Differential expression analysis of two groups was performed using the DESeq2 from R package. we find the ensemble of genes encoding extracellular matrix and ECM-associated proteins, which was termed as matrisome, was enriched at the top of the GSEA list.In the ensemble, there were pro-fibrotic cytokine genes such as TGFB1 and FGFs, and WNTs; ECM degradation enzymes genes such MMPs and CTSs; ECM-associated chemokine such CCL13 and CCL18; and notably, remarkable amount of glycoprotein/ proteoglycan genes such as LRG1, PRG4, HAPLN1 and PODNL1.

Spatial transcriptomics combined with single-cell RNA-sequencing unravels the complex inflammatory cell network in atopic dermatitis [ST]

Project description:Atopic dermatitis (AD) is the most common chronic inflammatory skin disease with complex pathogenesis. Using spatial and single-cell transcriptomics of whole skin biopsy and suction blister material, we investigated the cellular and molecular features of the leukocyte-infiltrated area in AD. We identified unique clusters of fibroblasts, dendritic cells, macrophages, and T cells in the lesional AD skin and molecular interactions between these cells. The leukocyte-infiltrated areas in lesional AD skin showed upregulation of COL6A5, COL4A1, TNC, IL32, CCL19 in COL18A1-expressing fibroblasts. Additionally, M2 macrophages expressed CCL13 and CCL18 in the same localization. Ligand–receptor interaction analysis of the spatial transcriptome identified a neighboring infiltration and interaction between activated COL18A1-expressing fibroblasts, activated CCL13- and CCL18-expressing M2 macrophages, CCR7- and LAMP3-expressing DCs, and T cells. As observed in skin lesions, serum levels of TNC and CCL18 were significantly elevated in AD and correlated with clinical disease severity.

Hyaluronan And Proteoglycan Link Protein 1 (HAPLN1) promotes Proliferation and Pro-inflammatory phenotype but not mobility of Fibroblast-like Synoviocytes

Project description:Objectives: HAPLN1 stabilize the macromolecular structure of the extracellular matrix (ECM) and its expression is increased in a few types of musculoskeletal diseases including rheumatoid arthritis (RA). However, its functions are obscure. Methods: Here, how HAPLN1 contributes to the viability, proliferation, mobility and pro-inflammatory phenotype of RA-FLSs was investigated using small interfering RNA (siHAPLN1), over-expression vector (HAPLN1OE) and a recombinant HAPLN1 (rHAPLN1) protein. Results: Interestingly, HAPLN1 promoted proliferation but inhibited migration of RA-FLSs. Earlier we reported the function of metformin, an AMPK activator, in the inhibition of FLSs activation but promotion of HAPLN1 secretion. In this study, we confirmed the findings of up-regulated HAPLN1 in RA patients, and it is positively correlated with AMPK. Both si-HAPLN1 and HAPLN1OE treatment has down-regulated the expression of AMPK-ɑ gene but the levels of phosphorylated AMPK-ɑ were found to be up-regulated in RA-FLSs. Furthermore, si-HAPLN1 had down-regulated the gene and protein expression of proinflammatory factors like TNF-ɑ, MMPs and IL-6, while HAPLN1OE up-regulated their levels. qPCR assay also indicated down regulated TGF-β, ACAN, Fibronectin, collagen Ⅱ, and Ki-67 by si-HAPLN1 treatment, while up-regulated ACAN, Ki-67 and down regulated cyclin-D1 by HAPLN1OE treatment. Proteomics of si-HAPLN1, rHAPLN1 and mRNA-Seq analysis of rHAPLN1 confirmed the functions of HAPLN1 in the activation of inflammation, proliferation, increased cell adhesion, and strengthening of ECM function. Conclusions: Collectively, these findings demonstrate HAPLN1 function in promoting proliferation and pro-inflammatory phenotype of RA-FLSs, which in turn could contribute to RA pathogenesis.

Pulmonary Eosinophilic Granulomatosis with Polyangiitis has IgG4 Plasma Cells and Immunoregulatory Features

Project description:The pathologic findings and immunologic mechanisms in eosinophilic granulomatosis with polyangiitis (EGPA) are poorly understood. To characterize pulmonary EGPA’s mechanisms, we examined EGPA paraffin-embedded lung biopsies by immunostaining, RNA sequencing, and reverse transcriptase PCR, compared to normal lung. EGPA lung infiltrates had eosinophils, alveolar macrophages, B and T cells, plasma cells, basophils, and mast cells. Mast cell degranulation was sparse. PhosphoSMAD2 immunostaining suggests TGFβ activity. Using both immunostaining and RNA-sequencing, showed significant increases for both type 2 related genes (CD209, TNFSF14 (induces TGFβ and IL-13)), immunoregulatory genes (FOXP3, CYP27B1 (makes calcitriol), ALOX15 and particularly IGHG4). Regulatory T cells and IgG4 plasma cells with IgG4-containing presumed immune complexes coating macrophages, were strikingly abundant relative to controls. HPGD (metabolizes prostaglandins and other eicosanoids) was substantially decreased. RNA studies also showed increased contents of collagen transcripts, IL13, CCL18, and CCL13. These findings suggest a novel mechanism involving alveolar macrophages, activated by ALOX15-eicosanoid products, making chemokines CCL18 and CCL13 and thus inducing a mixed type 2 plus immunoregulatory immune response. This infiltrate resembles the immune response to an invasive parasite rather than the IgE / mast cell degranulation response to luminal parasites or in asthma and other classic allergies. These findings also suggest new potential treatment targets for EGPA.

Suppression of T Cell Activation and Collagen Accumulation by an Anti-IFNAR1 mAb, Anifrolumab, in Adult Patients with Systemic Sclerosis

Project description:Type I IFNs are implicated in the pathophysiology of systemic sclerosis (SSc). Recently, a Phase I open-label trial was conducted with an anti-IFNAR1 receptor antibody (anifrolumab) in adult SSc patients. In this study, we aim to assess the downstream effects of anifrolumab and elucidate the role of type I IFN in SSc. Serum proteins and extracellular matrix (ECM) markers were measured in relation to IFN pathway activation status and SSc disease activity. Our results demonstrated a robust overexpression of multiple serum proteins in SSc patients, particularly those with an elevated baseline type I IFN gene signature. Anifrolumab administration was associated with significant downregulation of T cell–associated proteins and upregulation of type III collagen degradation marker. Whole-blood and skin microarray results also indicated the inhibition of T cell receptor and ECM–related transcripts by anifrolumab. In summary, our study demonstrates suppressive effects of anifrolumab on T cell activation and collagen accumulation through which tissue fibrosis may be reduced in SSc patients. The relationship between these peripheral markers and the clinical response to anifrolumab may be examined in larger double-blind, placebo-controlled trials. PAXGene whole blood tubes were collected from 29 SSc subjects at baseline and day 56 after anifrolumab administration, and skin biopsies were procured from 10 SSc subjects at baseline and day 28 after multiple-doses of anifrolumab administration.

IL-25 participates in keratinocyte-driven dermal matrix turnover and is reduced in Systemic Sclerosis epidermis

Project description:Aberrant deposition of extracellular matrix (ECM) resulting in dermal fibrosis is a hallmark of systemic sclerosis (SSc). Evidence suggests that dysfunctional SSc keratinocytes may contribute to fibrosis by altering dermal homeostasis. Whether interleukin-25 (IL-25), an IL-17 family member involved in epithelial/mesenchymal/immune cell interplay takes part in skin fibrosis is unknown. Here we address the role of IL-25 in SSc skin fibrosis. Compared to healthy donor (HD), in SSc and scleroderma-like disorders the epidermis expressed significantly lower levels of IL-25. In epidermal equivalents, IL-25 regulated several molecular pathways related to wound healing and ECM remodeling. Compared to control conditioned medium (CM), the CM from IL-25-primed keratinocytes enhanced the production by fibroblasts of matrix metalloproteinase-1 (MMP-1), IL-6, IL-8 (p< 0.05), but not of type-I collagen (Col-I ) nor fibronectin. However, IL- 25 significantly reduced the production of Col-I when applied directly to fibroblasts. The activation of keratinocytes by IL-25 was receptor-dependent and evident after a very short incubation time (10 min), largely mediated by IL-1, suggesting enhanced and specific release of preformed mediators. These results show that IL-25 participates to skin homeostasis and its decreased expression in SSc may contribute to skin fibrosis by favoring ECM deposition over degradation.

HAPLN1 potentiates peritoneal metastasis in pancreatic cancer

Project description:Pancreatic ductal adenocarcinoma (PDAC) frequently metastasizes into the peritoneum, which contributes to poor prognosis. Metastatic spreading is promoted by cancer cell plasticity, yet its regulation by the microenvironment is incompletely understood. Here, we show that the presence of hyaluronan and proteoglycan link protein-1 (HAPLN1) in the extracellular matrix enhances tumor cell plasticity and PDAC metastasis. Bioinformatic analysis showed that HAPLN1 expression is enriched in the basal PDAC subtype and associated with worse overall patient survival. In a mouse model for peritoneal carcinomatosis, HAPLN1-induced immunomodulation favored a more permissive microenvironment, which accelerated the peritoneal spread of tumor cells. Mechanistically, HAPLN1, via upregulation of tumor necrosis factor receptor 2 (TNFR2), promoted TNF-mediated upregulation of Hyaluronan (HA) production, facilitating EMT, stemness, invasion and immunomodulation. Extracellular HAPLN1 modified cancer cells and fibroblasts, rendering them more immunomodulatory. As such, we identified HAPLN1 as a prognostic marker and as a driver for peritoneal metastasis in PDAC.

A unifying gene signature for adenoid cystic cancer identifies parallel MYB-dependent and MYB-independent therapeutic targets (microRNA)

Project description:MYB activation is proposed to underlie development of adenoid cystic cancer (ACC), an aggressive salivary gland tumor with no effective systemic treatments. To discover druggable targets for ACC, we performed global mRNA/miRNA analyses of 12 ACC with matched normal tissues, and compared these data with 14 mucoepidermoid carcinomas (MEC) and 11 salivary adenocarcinomas (ADC). We detected a unique ACC gene signature of 1160 mRNAs and 22 miRNAs. MYB was the top-scoring gene (18-fold induction), however we observed the same signature in ACC without detectable MYB gene rearrangements. We also found 4 ACC tumors (1 among our 12 cases and 3 from public databases) with negligible MYB expression that retained the same ACC mRNA signature including over-expression of extracellular matrix (ECM) genes. Integration of this signature with somatic mutational analyses suggests that NOTCH1 and RUNX1 participate with MYB to activate ECM elements including the VCAN/HAPLN1 complex. We observed that forced MYB-NFIB expression in human salivary gland cells alters cell morphology and cell adhesion in vitro and depletion of VCAN blocked tumor cell growth of a short-term ACC tumor culture. In summary, we identified a unique ACC signature with parallel MYB-dependent and independent biomarkers and identified VCAN/HAPLN1 complexes as a potential target.
