Dengue virus (DENV) is a mosquito-borne virus belonging to the Flaviviridae family. There are 4 serotypes of DENV that cause human disease through transmission by mosquito vectors. DENV infection results in a broad spectrum of clinical symptoms, ranging from mild fever to dengue hemorrhagic ..., Abstract

IκB kinase ε (IKKε) is a non-canonical IκB kinase that is extensively studied in the context of innate immune response. Recently, significant progress has been made in understanding the role of IKKεin interferon (IFN) signaling. In addition to its roles in innate immunity, recent studies also ..., Abstract

HEp-2 cells persistently infected with respiratory syncytial virus (RSV) are a heterogeneous mixture of viral antigen-positive and -negative variants; however, the mechanism through which viral replication becomes latent remains unclear. In this study, we investigated the potential mechanism by ..., Abstract

A novel avian influenza A (H7N9) virus recently emerged in the Yangtze River delta and caused diseases, often severe, in over 130 people. This H7N9 virus appeared to infect humans with greater ease than previous avian influenza virus subtypes such as H5N1 and H9N2. While there are other potential ..., Abstract

The suppressive capacity of regulatory T cells (Tregs) has been extensively studied and is well established for many diseases. The expansion, accumulation, and activation of Tregs in viral infections are of major interest in order to find ways to alter Treg functions for therapeutic benefit. Tregs ..., Abstract

Plasmid DNA, an effective vaccine vector, can induce both cellular and humoral immune responses. However, plasmid DNA raises issues concerning potential genomic integration after injection. This issue should be considered in preclinical studies. Tiantan vaccinia virus (TV) has been most widely ..., Abstract

Lepidopteran heat-tolerant (ht) cell lines have been obtained with sf-9, sf-21 and several Bombyx cells. They have a distinct karyotype, membrane lipid composition, morphology and growth kinetics from the parental cell lines. In this paper, we report the development of ht cell lines from other ..., Abstract

To obtain the P8 protein of Rice gall dwarf virus (RGDV) with biological activity, its outer coat protein gene S8 was expressed in Spodoptera frugiperda (Sf9) insect cells using the baculovirus expression system. The S8 gene was subcloned into the pFastBacTM1 vector, to produce the recombinant ..., Abstract

Herpes simplex viruses (HSV-1 and HSV-2) cause global morbidity and synergistically correlate with HIV infection. HSV exists life-long in a latent form in sensory neurons with intermittent reactivation, in despite of host immune surveillance. While abundant evidence for HSV interfering with innate ..., Abstract

The genes of C terminal of HCV NS3 region of two chronic patients in two different time were sequenced to analyse the conservation of a helper T cell epitope in HCV NS3 protein (amino acids 1248 to 1261). The epitope was synthesized and the immune response to it in a self limited patient and two ..., Abstract

The baculovirus insect cell expression system was used to prepare the HPV16 E 6 recombinant protein. The HPV16 E 6 complete ORF amplified by PCR from HPV16 genome was T A cloned into the baculovirus transfer vector pVL1393 T under AcMNPV Polh. This recombinant transfer plasmid pVL1393 E 6 DNA and ..., Abstract
