Project description:Protein arginine methyltransferase 5 (Prmt5) is the major type II methyltransferase catalyzing symmetric dimethylation, regulates cell development, homeostatic and disease processes. Prmt5 inhibition or deletion in CD4+T cells has been reported to protection against experimental autoimmune encephalomyelitis (EAE), the perfect mouse model for multiple sclerosis (MS); however, the detail mechanisms have not yet been elucidated. Here, using the mRNA sequencing, single cell RNA sequencing and ATAC sequencing, we uncovered the unreported role of Prmt5 on T cells migration ability under the EAE condition. We found that mice condition knockout of Prmt5 in T cells were resistance with EAE, infiltrating inflammatory CD4+ T cells in center nervous system (CNS) were greatly reduced. However, T cells in spleen showed much more proliferation and activation properties in Prmt5cko mice, the number of pathogenic CD4+T cells in spleen were not reduced. We further revealed that Rora+CD4+T cells were elevated in Prmt5cko mice, but expressed lower level of S1pr1, resulting in a lack of CD4+ T cells egress from spleen and migrate to CNS, leading to pathogenic CD4+T cells were blocked in spleen. Moreover, single cell ATAC sequencing revealed that Klf2 were enriched in S1pr1 promoter and reduced in Prmt5cko mice. Correctively, our study delineated the undiscovered role of Prmt5 on T cell biology, Prmt5 may through Klf2-S1pr1 pathway and regulate T cells migration; modulating Prmt5 levels may be useful for controlling CD4+T cell migration in CD4+T cell mediated diseases including MS.

Project description:Chronic inflammatory demyelinating polyneuropathy (CIDP) is a debilitating condition caused by autoimmune demyelination of peripheral nerves. CIDP is associated with increased IL-10, a cytokine with well-described anti-inflammatory effects. However, the role of IL-10 in CIDP is unclear. In this study, we demonstrate that IL-10 paradoxically exacerbates autoimmunity against peripheral nerves. In IL-10-deficient mice, protection from neuropathy was associated with an accrual of highly activated CD4+ T cells in draining lymph nodes and absence of infiltrating immune cells in peripheral nerves. Accumulated CD4+ T cells in draining lymph nodes of IL-10-deficient mice expressed lower sphingosine-1-phosphate receptor 1 (S1pr1), a protein important in lymphocyte egress. Additionally, IL-10 stimulation in vitro induced S1pr1 expression in lymph node cells in a STAT3-dependent manner. Together, these results delineate a novel mechanism in which IL-10-induced STAT3 increases S1pr1 expression and CD4+ T cell migration to accelerate T cell-mediated destruction of peripheral nerves.

Project description:Multiple Sclerosis (MS) is a debilitating central nervous system disorder associated with inflammatory T cells. Activation and expansion of inflammatory T cells is thought to be behind MS relapses and influence disease severity. Protein arginine N-methyltransferase 5 (PRMT5) is a T cell activation-induced enzyme that symmetrically dimethylates proteins and promotes T cell proliferation. However, the mechanism behind PRMT5-mediated control of T cell proliferation and whether PRMT5 contributes to diseases severity is unclear. Here, we evaluated the role of PRMT5 on cyclin/cdk pairs and cell cycle progression, as well as PRMT5's link to disease severity in an animal model of relapsing-remitting MS. Treatment of T helper 1 (mTh1) cells with the selective PRMT5 inhibitor, HLCL65, arrested activation-induced T cell proliferation at the G1 stage of the cell cycle, suggesting PRMT5 promotes cell cycle progression in CD4+ T cells. The Cyclin E1/Cdk2 pair promoting G1/S progression was also decreased after PRMT5 inhibition, as was the phosphorylation of retinoblastoma. In the SJL mouse relapsing-remitting model of MS, the highest PRMT5 expression in central nervous system-infiltrating cells corresponded to peak and relapse timepoints. PRMT5 expression also positively correlated with increasing CD4 Th cell composition, disease severity and Cyclin E1 expression. These data indicate that PRMT5 promotes G1/S cell cycle progression and suggest that this effect influences disease severity and/or progression in the animal model of MS. Modulating PRMT5 levels may be useful for controlling T cell expansion in T cell-mediated diseases including MS.

Project description:KLF2, a member of the Kruppel-like factor (KLF) family, is thought to be a tumor suppressor in many kinds of malignant tumors. Its functions in prostate cancer (PCa) are unknown. This study aimed to explore the role of KLF2 in the migration and invasion of PCa cells. The expression of KLF2 was measured by immunohistochemistry in PCa tissues and in paired non-tumor tissues. KLF2 and MMP2 expression in cells was measured by Western blot and RT-qPCR. Adenoviruses and siRNAs were used in cell function tests to investigate the role of KLF2 in regulating MMP2. Interactions between KLF2 and MMP2 were analyzed by a luciferase activity assay. The present study, for the first time, identified that KLF2 was downregulated both in PCa clinical tissue samples and in cancer cell lines. The overexpression of KLF2 inhibited the migration and invasion of PCa cells via the suppression of MMP2.This study demonstrates that KLF2 might act as a tumor suppressor gene in PCa and that the pharmaceutical upregulation of KLF2 may be a potential approach for treatment.
