Gene expression in cutaneous lupus erythematosus

ABSTRACT: Lesional skin biopsies were taken from patients with active, untreated lupus skin disease (chronic discoid lupus erythematosus, CDLE, n=6; subacute cutaneous lupus erythematosus, SCLE, n=5). Healthy control specimens (HC) were obtained from healthy skin of 5 patients undergoing plastic surgery. In every case, two 4mm punch biopsies were taken. One was flash-frozen in liquid nitrogen and afterwards processed for mRNA isolation. The second biopsy was fixed in 5% formalin solution overnight, and was proceeded for histological investigation.The one-color Agilent 60-mer oligo microarray (Agilent, Santa Clara, CA) was used for gene expression analyses. Statistical analyses were performed using the Agilent Feature Extraction Softwareâ¢ and the Rosetta Resolverâ¢ gene expression data analysis system. The presented gene list (Table S1) includes normalized sample/ control log10-ratios (expression > 2-fold enhanced, p<0.01).

Autoantigen microarrays of NZM2328 lupus mice treated with induced CD4+ regulatory T cells or natural CD4+ regulatory T cells

Project description:Foxp3+ regulatory T cells (Treg), playing a crucial role in the maintenance of immune tolerance and prevention of autoimmune diseases, consist of thymus-derived naturally-occurring CD4+Foxp3+ Treg cells (nTreg) and another CD4+Foxp3+ Treg cells that can be induced ex vivo with TGF-Î² (iTreg). Although both Treg subsets share similar phenotypes and functional characteristics, they also have potential biologic differences on their biology. However, the role of iTreg in regulating B cells of lupus disease mice remains unclear so far. The lupus-prone New Zealand Mixed 2328 (NZM2328) mouse, a recombinant inbred strain that originated from the crosses among New Zealand Black and New Zealand White mice and their progenies also develops Lupus Glomerulonephritis. NZM2328 mice develop autoantibodies and glomerulonephritis with female predominance similarly to humans with systemic lupus erythematosus. The lupus disease onset is usually around 3-4 months age. In our experiments, iTreg induced from NZM2328 lupus-prone mice (10-12 weeks old) and nTreg sorted from the thymus of 10-12 weeks old NZM2328 lupus-prone mice were adoptively transferred into old NZM2328 mice (>4 months age) with established lupus for 32 days. Totally, there were three groups including NZM2328 mice as model (receive PBS), NZM2328 mice received iTreg, and NZM2328 received nTreg. The serum IgG and IgM autoantibody were detected by autoantibodies microarrays (UTSW Medical Center Autoantigen Array) at days 0, 14, 32 after cell transfer. Our results demonstrated that adoptive transfer of iTreg had a superior effect than nTreg subset on suppressing lupus B cell responses in vivo.

single cell RNA sequencing reveals cellular heterogeneity of DLE and SLE

Project description:Lupus, a server and complex autoimmune disease, is clinically divided into cutaneous lupus erythematosus (CLE) which featured in skin damage, and systemic lupus erythematosus (SLE) which characterized in systemic multi-organ damage. The distinction of these two types of lupus is widely unknown. Here, we collected 23 skin biopsies of healthy control(HC), DLE (discoid lupus erythematosus, a main type of CLE) and SLE, separated epidermis and dermis and performed single cell RNA sequencing through microfluidics based 10x genomics system. Our results demonstrated larger numbers of immune cells infiltrated in skin lesions of DLE than SLE, which may help to distinguish them. Then, non-immune cells such as keratinocytes and fibroblasts were showed functions like immune cells. Moreover, ISGs(interferon stimulated genes), HSP70 coding genes were found to be overexpressed in multi expanded subclusters. Some biological progresses such as autophagy and neutrophil activation were enriched in expanded subclusters.

Epidermal gene expression in wound healing and after ex vivo injury

Project description:Human in vivo skin wound: Non-wounded skin was obtained by taking punch biopsies from three healthy donors (donor 1,2 and 3). The samples were termed 'skin day 0 in vivo wound'. Skin wound samples were retrieved by making new punch biopsies from the edge of the original biopsies after four days. These samples were termed 'skin day 4 in vivo wound'. As much dermal tissue as possible was removed by dissection to make sure mainly epidermis was present in the samples. The samples were washed in NaCl to possible remove infiltrating inflammatory cells before RNA isolation. Ex vivo skin wounds: Skin was obtained from three healthy donors following reduction surgery (donor 1, 2, and 3). As much dermal tissue as possible was removed dissection. These samples were termed 'skin day 0 ex vivo wound'. Skin was sliced into 1x10 mm slices and incubated in keratinocyte medium for four days with either 1:1000 fold dilution of DMSO or 10 micromolar AG-1478 (dissolved in DMSO). Again as much dermal tissue was removed by dissection as possible before RNA was isolated. These samples were termed 'skin day 4 ex vivo wound' and 'skin day 4 AG-1478 ex vivo wound'. By comparing the gene expression day 4 in ex vivo wound with in vivo wounds it was possible to see which part of the gene expression in wounded skin that was due to the epidermal reaction to injury and how much was due to stimuli from infiltrating inflammatory cells absent in the ex vivo skin wounds. By comparing the data from ex vivo skin wounds day 4 with and without the EGFR-inhibitor AG-1478, it was possible to look at the importance of the EGF-receptor of EGFR for the gene expression in ex vivo wounded skin.
