A unique avian-origin A/H7N9 influenza virus has so far caused 134 cases with 44 deaths. Probing the host factors contributing to disease severity, we found that lower levels of plasma inflammatory cytokines on hospital admission correlated with faster recovery in 18 patients with A/H7N9 influenza virus, whereas high concentrations of (in particular) IL-6,(More)
We describe an analytical method of vascular smooth muscle cell membrane chromatography (VSM/CMC) combined with gas chromatography/mass spectrometry (GC/MS) for recognition, separation and identification of active components from traditional Chinese medicines (TCMs). VSM cells by means of primary culture with rat thoracic aortas were used for preparation of(More)
BACKGROUND AND OBJECTIVE We conducted epidemiologic investigations and serologic assays on household contacts that were extensively exposed to three influenza A (H7N9) virus infected case-patients before infection-control practices were implemented. STUDY DESIGN Data on the early clinical course of each patient and the exposure history for each patient's(More)
Recombination contributes substantially to the genetic diversity of HIV-1, and is likely to occur in populations in which multiple subtypes circulate. Molecular epidemiological studies showed that subtype B, CRF01_AE, and CRF07_BC are currently circulating in parallel among men who have sex with men (MSM) in China, suggesting the possible emergence of new(More)
The aim of this study was to test whether deglycosylation of an HIV-1 AE recombinant-derived gp140 could enhance the induction of neutralizing antibodies. N-to-Q mutations were introduced in the V1/V2 (m157/161) or V4 (m382/388) loops by using overlapping PCR. BALB/c mice were inoculated with different DNA vaccines at weeks 0, 2, 4, and 7. The Elispot assay(More)
Transmission plays a central role in the ecology of baculoviruses and the population dynamics of their hosts. Here, we report on the horizontal and vertical transmission dynamics of wild-type Helicoverpa armigera single-nucleocapsid nucleopolyhedrovirus (HaSNPV-WT) and a genetically modified variant (HaSNPV-AaIT) with enhanced speed of action through the(More)
Few studies on the humoral immune responses in human during natural influenza infection have been reported. Here, we used serum samples from pandemic 2009 H1N1 influenza infected patients to characterize the humoral immune responses to influenza during natural infection in humans. We observed for the first time that the pandemic 2009 H1N1 influenza induced(More)
SAMHD1 restricts human immunodeficiency virus type 1 (HIV-1) replication in myeloid cells and CD4+ T cells, while Vpx can mediate SAMHD1 degradation to promote HIV-1 replication. Although the restriction mechanisms of SAMHD1 have been well-described, SAMHD1 expression and Vpx-mediated SAMHD1 degradation during chronic HIV-1 infection were poorly understood.(More)
To determine whether CRF07_BC, one of the most predominant strains that accounts for one third HIV-1 prevalence in China, has the ability to infect hematopoietic progenitor cells (HPCs), human Umbilical Cord Blood (UCB) derived CD34+ HPCs isolated with high purity were infected by HIV-1 pseudotyped with CRF07_BC envelope. After HIV-1 infection, ~0.86% CD34+(More)
