Endogenous retroviruses promote aberrant T cell differentiation in systemic lupus erythematosus via the RIG-I pathway [SLE]

ABSTRACT: The dysregulated differentiation of T lymphocytes play an important role in systemic lupus erythematosus (SLE). However, the underlying mechanism remains unclear. Here, we screened and identified many overexpressed HERVs in CD4+ T cells from SLE patients by RNA-seq and found that some HERVs formed dsRNAs to induce the activation of the RIG-I signaling pathway. And our findings reveal the roles and mechanism of HERVs and RIG-I in regulating the aberrant differentiation of T cells in SLE patients.

Endogenous retroviruses promote aberrant T cell differentiation in systemic lupus erythematosus via the RIG-I pathway [whole transcriptomics]

Project description:The dysregulated differentiation of T lymphocytes play an important role in systemic lupus erythematosus (SLE). However, the underlying mechanism remains unclear. Here, we screened and identified many overexpressed HERVs in CD4+ T cells from SLE patients by whole transcriptome resequencing and found that some HERVs formed dsRNAs to induce the activation of the RIG-I signaling pathway. And our findings reveal the roles and mechanism of HERVs and RIG-I in regulating the aberrant differentiation of T cells in SLE patients.

Endogenous retroviruses promote aberrant T cell differentiation in systemic lupus erythematosus via the RIG-I pathway [naïve]

Project description:The dysregulated differentiation of T lymphocytes play an important role in systemic lupus erythematosus (SLE). However, the underlying mechanism remains unclear. Our findings reveal many overexpressed HERVs in CD4+ T cells from SLE patients. To investigate the role of dsRNA/RIG-I pathway in CD4+ T cell differentiation, RNA-seq was performed in CD3 and CD28 antibodies activated naive CD4+ T cells transfected with poly(I:C). The expression profiles of genes related to the effector T cell differentiation reveal that dsRNAs induced the activation of the RIG-I signaling pathway plays important roles in aberrant differentiation of T cells.

Endogenous retroviruses promote aberrant T cell differentiation in systemic lupus erythematosus via the RIG-I pathway [mouse_CD4]

Project description:The dysregulated differentiation of T lymphocytes play an important role in systemic lupus erythematosus (SLE). However, the underlying mechanism remains unclear. Here, we screened for differentially expressed genes in CD4+T cells derived from WT and DDX58 KO mice by RNA-seq. And our findings reveal the roles and mechanism of RIG-I in regulating the aberrant differentiation of T cells in SLE patients.

Ultraviolet light induces HERV expression to activate RIG-I signaling pathway in keratinocytes

Project description:Skin inflammation and photosensitivity are common in lupus erythematosus (LE) patients, and Ultraviolet (UV) light is a known trigger of skin and possibly systemic inflammation in systemic lupus erythematosus (SLE) and discoid lupus erythematosus (DLE) patients. Type I interferons (IFN) are upregulated in LE skin after UV exposure, however, the mechanisms to explain UVB-induced inflammation remain unclear. Here we performed RNA-seq to HaCat cells with UVB irradiation to characterize gene expression and resolve differential responses of keratinocytes, in order to understand how the keratinocyte response contributes to the disease. Our data showed that HERVs and RIG-I pathway were activated in keratinocytes after UVB exposure and indicate that RIG-I pathway and HERVs are involved in proinflammatory by activating the I-IFN pathway, which provide a novel insight into how UVB promotes and aggravate skin lesion of LE patients.

Gene expression in RNP autoantibody+ systemic lupus erythematosus (SLE) patient blood

Project description:The goal of this study was to characterize gene expression profiles in RNP autoantibody+ SLE versus healthy blood donors with a focus on select cytokines that may be important in B cell activation and differentiation, including BAFF, IL-21, and IL-33. We utilized Affymetrix microarrays to characterize the global program of gene expression in the SLE patients, and to identify differentially expressed genes in patients compared to healthy controls. We examined a cohort of 79 consecutive patients classified as anti-ribonuclear protein (anti-RNP)+ systemic lupus erythematosus (SLE). All patients provided RNA samples obtained after providing informed consent. There were 73 female and 6 male subjects. Disease duration ranged from 0 to 453 months with a median of 37.5 months. SLE Disease Activity Index (SLEDAI) ranged from 0 to 31 with a median of 6. mRNA from the blood of a SLE cohort (79 patients with some repeat visits for a total of 99 arrays) and 30 healthy volunteers (one array per volunteer) were analyzed.

Transcriptomic signature in patients with systemic lupus erythematosus (SLE) [T cells]

Project description:T cell abnormalities are well-known features of patients with systemic lupus erythematosus (SLE). The role of CD4 and CD8 T lymphocytes, however, remains poorly understood with data suggesting both protective and deleterious roles. This project aimed to identify a cell-specific transcriptional signature in patients with SLE that could be used as a prognostic disease marker. The overall objective is to correlate the clinical presentation with specific RNA signatures to determine if there are signatures that correlate with disease outcome

RNA-seq of peripheral blood mononuclear cell (PBMC) derived from normal healthy donors and systemic lupus erythematosus (SLE) patients

Project description:Systemic lupus erythematosus (SLE), also known simply as lupus, is an autoimmune disease. There is no cure for SLE. The mechanism involves an immune response by autoantibodies against a person's own tissues. However, the mechanism underlying imbalance of autoantibodies is not clear. In this experiment, peripheral blood was obtained from normal healthy donors and systemic lupus erythematosus (SLE) patients. Peripheral blood mononuclear cells (PBMC) were separated by Ficoll separation solution. Samples of four (total eight) donors were pooled and Samples of four (total eight) SLE patients were pooled. The aim was to characterize the mRNA profile of SLE patients compared to healthy donors and find the new target of diagnosis or treatment for SLE.

Autoantibody profiling of sera from individuals with Systemic Lupus Erythematosus (SLE) by protein microarray

Project description:We developed a protein microarray to identify autoantigens in Systemic Lupus Erythematosus (SLE). Baculovirus-Sf9 cell expression system was used to create a protein microarray with 1543 full-length human proteins expressed with a biotin carboxyl carrier protein (BCCP) folding tag. We assayed sera from UK and USA SLE individuals (total n=277), age/ancestry matched control cohorts (n=280) and a confounding disease cohort (n=92).
