Japanese encephalitis (JE) is the most common mosquito-borne encephalitis in the Asia-Pacific region. Patients with JE usually present neuronal involvement, but other organ involvement is relatively rare. Employing human neuroblast-derived (NB) cell lines and different blood cells (erythrocytes, lymphocytes, granulocytes and monocytes), the neurotropism and(More)
BACKGROUND the C-type lectin DC-SIGN (CD209) is known to be the major dengue receptor on human dendritic cells, and a single nucleotide polymorphism (SNP) in the promoter region of CD209 (-336 A/G; rs4804803) is susceptible to many infectious diseases. We reason that variations in the DC-SIGN gene might have a broad influence on viral replication and host(More)
OBJECTIVE Suppressors of cytokine signalling (SOCS) proteins regulate cytokine responses and control immune balance. The objective of our study was to determine whether the expression of SOCS1 and its potential regulatory microRNAs (miRNAs) in leukocytes is correlated to the development of dengue haemorrhagic fever (DHF). METHODS We performed a(More)
BACKGROUND Bone morphogenetic protein 9 (BMP9) and Wnt/β-catenin signaling pathways are able to induce osteogenic differentiation of mesenchymal stem cells (MSCs), but the role of Wnt/β-catenin signaling pathway in BMP9-induced osteogenic differentiation is not well understood. Thus, our experiment was undertaken to investigate the interaction between BMP9(More)
Extracorporeal shock wave (ESW) is an alternative non-invasive method for the promotion of bone growth and tendon repair. In an animal model, we have reported that ESW promoted bone marrow osteoprogenitor growth through transforming growth factor-beta1 induction. We have further explored the mechanism for the ESW promotion of osteogenesis. Results showed(More)
BACKGROUND Papillary thyroid carcinoma (PTC) are clinicopathogenetically heterogeneous. Micro-RNAs (miRNAs) are involved in the pathogenesis of diverse human cancers, including PTC. Information regarding associations between clinicopathological features of PTC with the expression of specific miRNAs, however, is sparse. In this study, we compared expression(More)
T helper type 1 (Th1) cells perform a critical role in fighting intracellular organisms, and interleukin-12 (IL-12) is known to promote a Thl response. This study was conducted to identify whether an IL-12-independent Th1 reaction is induced by the varicella-zoster virus (VZV) in human beings. It was found that different intracellular microorganisms could(More)
Atopic asthma is a complex disease associated with IgE-mediated immune reactions. Numerous genome-wide studies identified more than 100 genes in 22 chromosomes associated with atopic asthma, and different genetic backgrounds in different environments could modulate susceptibility to atopic asthma. Current knowledge emphasizes the effect of tobacco smoke on(More)
Severe acute respiratory syndrome (SARS) has spread to a global pandemic, especially in Asia. The transmission route of SARS has been clarified, but the immunopathogenesis of SARS is unclear. In an age-matched case-control design, we studied immune parameters in 15 SARS patients who were previously healthy. Plasma was harvested for detection of virus load,(More)
Tumor necrosis factor-alpha (TNF-alpha) and soluble TNF receptors (sTNFR1 and sTNFR2) have been implicated in infectious diseases. We investigated dynamic changes among TNF-alpha, membrane TNF receptors (mTNFR1 and mTNFR2), and sTNFR1 and sTNFR2 levels for patients with dengue hemorrhagic fever (DHF) and those not infected during a DEN-2 outbreak in(More)
