Hemorrhagic fever with renal syndrome (HFRS) is an acute infectious disease characterized by endothelial cell dysfunction, which results in plasma exosmosis, hyperpermeability, and sometimes hemorrhages. As one of the vascular permeability cytokines, vascular endothelial growth factor (VEGF) might mediate the hyperpermeability caused by HFRS. In the present(More)
Rheumatoid arthritis (RA) is an immune-mediated disease with a pathogenesis that involves CD4 T cell activation. Multiple immune regulatory molecules expressed on CD4(+) T cells were involved in RA pathogenesis. In this study, we investigated the role of T cell immunoglobulin and ITIM (immunoreceptor tyrosine-based inhibition motif) domain (TIGIT) in RA.(More)
MicroRNAs (miRNAs) have been reported to have diverse biological roles in regulating many biological processes, including osteogenic differentiation. In the present study, we identified that miR-24 was a critical regulator during osteogenic differentiation. We found that overexpression of miR-24 significantly inhibited osteogenic differentiation, which(More)
Osteoporosis is a kind of metabolic bone disorder. MicroRNA-21 (miR-21) has been proven to play an important role in bone formation, whereas its role in osteoporosis is unclear. In the present study, miR-21 expression was inhibited by TNF-α in mesenchymal stem cells (MSCs). TNF-α induced cell apoptosis, and inhibited cell proliferation and differentiation(More)
The very late antigen-4 (VLA-4) bound to vascular cell adhesion molecule-1 could provide co-stimulatory signals for the activation of T lymphocytes, and these adhesion molecules play key roles in leukocyte adherence and propagation of inflammatory responses. We examined the levels of VLA-4 in the peripheral blood mononuclear cells (PBMC) of patients with(More)
The pathogenesis of hemorrhagic fever with renal syndrome (HFRS) has not been fully clarified. Cell-mediated immunity appears to play a crucial role in the immune pathogenesis of HFRS. To explore the relationship between Hantaan (HTNV)-specific CD8(+) T lymphocytes and the immune pathogenesis of HFRS, the levels of interferon γ (IFN-γ) secreted by(More)
Hemorrhagic fever with renal syndrome (HFRS) is an acute viral infectious disease characterized by fever, hemorrhage and renal failure. HFRS has become a serious public health problem in China. Unfortunately, the pathogenesis of HFRS has not been completely clarified. The aim of this study is to investigate the changes of decoy receptor 3 (DcR3) and to(More)
The variable region of murine immunoglobulin heavy chain (Igh) is assembled by sequential DH -JH and VH -DJH recombination. The accessibility of the Igh locus determines the order of rearrangement. Because of the large number of VH genes and the lack of a suitable model, the epigenetic modifications of VH genes after DJH recombination have not previously(More)
The genes encoding the immunoglobulin κ light chain are assembled during B cell development by V(D)J recombination. For efficient rearrangement, the Igκ locus must undergo a series of epigenetic changes. One such epigenetic mark is DNA methylation. The mechanism that the Igκ locus is selectively demethylated at the pre-B cell stage has not previously been(More)
