Project description:To elucidate the gene profile of anti-fibroproliferative effects of cyclosporine, we added TGF-b and/or CsA to MRC5 (fetal human lung fibroblast) cell line. After 24 hours serum starvation, fibroblasts were treated with 3 ng/ml TGF-β1 and were treated with or without 2μg/ml Cyclosporine and effects were examined at 48 hours after treatment. Expression of three genes (IGFBP3, ID1 and PPARG) from this signature was quantified in the same RNA samples by real-time PCR. TGF-β and cyclosporine induced gene expression data was measured in MRC5 (fetal human fibroblast cell line) at 48h after treatments. The dose of TGF-β was 3 ng/ml and cyclosporine was 2 μg/ml. The comparison was done between four groups (control, TGF-β, cyclosporine and TGF-β plus cyclosporine).Three independent experiments were performed at each treatments using different samples for each experiment.

Project description:Kidney peritubular capillaries are particularly susceptible to rarefaction and regeneration-limited after exposure to toxins or injuries. Studying these kidney microvessels remain challenging, primarily resulting from difficulties imaging in vivo, as well as isolating and culturing kidney microvascular cells in vitro, in particular in a three-dimensional (3D) microenvironment with proper hemodynamics. Here, we developed methods to isolate, purify, and characterize human kidney peritubular microvascular endothelial cells (hKMECs), and reconstituted a 3D kidney microvasculature in collagen matrix. Compared to other endothelial cells, isolated hKMECs are very sensitive to VEGF for survival and growth, and have a high vasculogenic but low angiogenic potential. Under flow, they formed a fenestrated endothelium with a comprehensive permeability barrier. When exposed to calcineurin inhibitors, hKMECs formed microvessels displayed cell retraction, broken fenestrae, and swollen endothelium, which led to a thrombogenic luminal wall and erythrocytes extravasations into the subendothelial space. Our study recapitulated the human kidney microvascular structure and function, and shed lights on potential mechanistic studies of kidney specific injuries and diseases.

Project description:Renal artery stenosis (RAS) caused by narrowing of arteries is characterized by microvascular damage. Macrophages are implicated in repair and injury, but the specific populations responsible for these divergent roles have not been identified. Here, we characterized murine kidney F4/80+CD64+ macrophages in three transcriptionally unique populations. Using fate-mapping and parabiosis studies, we demonstrate that CD11b/cint are long-lived kidney-resident (KRM) while CD11chiMf, CD11cloMf are monocyte-derived macrophages. In a murine model of RAS, KRM self-renewed, while CD11chiMf and CD11cloMf increased significantly, which was associated with loss of peritubular capillaries. Replacing the native KRM with monocyte-derived KRM using bone marrow transplantation followed by RAS, amplified loss of peritubular capillaries. To further elucidate the nature of interactions between KRM and peritubular endothelial cells, we performed RNA-sequencing on flow-sorted macrophages from Sham and RAS kidneys. KRM showed a prominent activation pattern in RAS with significant enrichment in reparative pathways, like angiogenesis and wound healing. In culture, KRM increased proliferation of renal peritubular endothelial cells implying direct pro-angiogenic properties. Human homologs of KRM identified as CD11bintCD11cintCD68+ increased in post-stenotic kidney biopsies from RAS patients compared to healthy human kidneys, and inversely correlated to kidney function. Thus, KRM may play protective roles in stenotic kidney injury through expansion and upregulation of pro-angiogenic pathways

Project description:Solid organ transplant represents a potentially lifesaving procedure for patients suffering from end-stage heart, lung, liver, and kidney failure. However, rejection remains a significant source of morbidity and immunosuppressive medications have significant toxicities. Janus kinase (JAK) inhibitors are effective immunosuppressants in autoimmune diseases and graft versus host disease after allogeneic hematopoietic cell transplantation. Here we examine the role of JAK inhibition in preclinical fully major histocompatibility mismatched skin and heart allograft models. Baricitinib combined with cyclosporine A (CsA) preserved fully major histocompatibility mismatched skin grafts for the entirety of a 111-day experimental period. In baricitinib plus CsA treated mice, circulating CD4+T-bet+ T cells, CD8+T-bet+ T cells, and CD4+FOXP3+ regulatory T cells were reduced. Single cell RNA sequencing revealed a unique expression profile in immune cells in the skin of baricitinib plus CsA treated mice, including decreased inflammatory neutrophils and increased CCR2- macrophages. In a fully major histocompatibility mismatched mismatched heart allograft model, baricitinib plus CsA prevented graft rejection for the entire 28-day treatment period compared with 9 days in controls. Our findings establish that the combination of baricitinib and CsA prevents rejection in allogeneic skin and heart graft models and supports the study of JAK inhibitors in human solid organ transplantation.

Project description:Since hair growth disorders can carry a major psychological burden, more effective human hair growth-modulatory agents need to be urgently developed. Here, we used the hypertrichosis-inducing immunosuppressant, cyclosporine A (CsA), as a lead compound to identify new hair growth-promoting targets. Through microarray analysis we identified the Wnt inhibitor, SFRP1, as being downregulated in the dermal papilla (DP) of CsA-treated human scalp hair follicles (HFs) ex vivo. Therefore, we further investigated the function of SFRP1 using a pharmacological approach and found that SFRP1 regulates intrafollicular canonical Wnt/β-catenin activity through inhibition of Wnt ligands in the human hair bulb. Conversely, inhibiting SFRP1 activity through the SFRP1 antagonist, WAY-316606, enhanced hair shaft production, hair shaft keratin expression and inhibited spontaneous HF regression (catagen) ex vivo. Collectively, these data (a) identify Wnt signaling as a novel, non-immune-inhibitory CsA target; (b) introduce SFRP1 as a physiologically important regulator of canonical β-catenin activity in a human (mini-)organ; and (c) demonstrate WAY-316606 to be a promising new promoter of human hair growth. Since inhibiting SFRP1 only facilitates Wnt signaling through ligands that are already present, this “ligand-limited” therapeutic strategy for promoting human hair growth may circumvent potential oncological risks associated with chronic Wnt over-activation. We used microarrays to identify novel hair growth promoting targets in human hair follicles through the use of cyclosporine A.

Project description:Infection of Gram-negative bacteria in female genital tract causes systematic immune-response and reproductive dysfunction. Immunosuppressor Cyclosporine A (CsA) is widely used in the treatment of genital tract immune response, however, the knowledge on the changes of transcriptome after CsA inhibiting lipopolysaccharide (LPS)-induced immune response still remains unknown.

Project description:Organ transplant recipients (OTRs) on Cyclosporine A (CSA) are prone to catastrophic cutaneous squamous cell carcinoma (SCC). Allograft-sparing, cancer-targeting systemic treatments are unavailable. We have shown increased risk for catastrophic SCC in OTRs via CSA-mediated induction of Interleukin-22 (IL-22). Herein, we found CSA drives SCC proliferation and tumor growth through IL-22 and JAK/STAT pathway induction. We in turn inhibited SCC growth with an FDA-approved JAK 1/2 inhibitor, Ruxolitinib. In human SCC cells, greatest proliferative response to IL-22 and CSA treatment occurred in non-metastasizing lines. IL-22 treatment upregulated JAK1 and STAT1/3 in A431 SCC cells. JAK/STAT pathway genes were highly expressed in tumors from a cohort of CSA-exposed OTRs, and in SCC with high risk for metastasis. Compared to immunocompetent SCC, genes associated with innate immunity, response to DNA damage and p53 regulation were differentially expressed in SCC from OTRs. In nude mice engrafted with human A431 cells, IL-22 and CSA treatment increased tumor growth and upregulated IL-22 receptor, JAK1 and STAT 1/3 expression. Ruxolitinib treatment significantly reduced tumor volume and reversed the accelerated tumor growth. CSA and IL-22 exacerbate aggressive behavior in SCC. Targeting the IL-22 axis via selective JAK/STAT inhibition may reduce the progression of aggressive SCC in OTRs, without compromising immunosuppression. In this study, microarray data was used to compare normal skin to immunocompetent SCC, to transplant associated SCC (TSCC)

Project description:Kidney transplant recipients with biopsy-proven microvascular injury (MVI) have increased risk for allograft failure. MVI is often caused by antibody-mediated injury that is resistant to available treatments. Current diagnostic methods are also inadequate, with interobserver variability in traditional pathology reads, variable assessment of circulating donor-specific antibody between HLA laboratories, and peritubular capillary C4d staining. Molecular assessments of kidney biopsies can provide improved sensitivity for diagnosing MVI and other allograft pathology, while improving reproducibility and objectivity. Most molecular classifiers have been based on whole genome sequencing to develop diagnostic tests, but have provided limited therapeutic targets. In this study, we pursued a candidate gene approach to measure WNT pathway genes in residual clinical FFPE biopsies with and without MVI. We focused on the WNT pathway because of previous translational studies that implicated this pathway in chronic renal allograft injury as well as vascular injury in native chronic kidney disease. Case-control study of 95 residual FFPE biopsies with MVI (g+ptc score >= 2, n=50) or Stable (g+ptc score < 2 and no other major abnormalities, n=45). Biopsies were retrieved from a biorepository of over 500 kidney transplant biopsies. We compared expression of 180 WNT pathway genes and 30 custom skipe-in targets (derived from previous studies of endothelial injury in transplantation) between MVI and Stable groups, with correction for multiple comparisons using FDR < 5%. This dataset is part of the TransQST collection.
