Arthritogenic alphaviruses are human pathogens maintained in nature through alternating replication in vertebrates and mosquitoes. Using chimeric viruses, we previously reported that replacement of the PE2 coding region of the T48 strain of Ross River virus (RRV-T48) with that from the attenuated
The role of the immunoreceptor tyrosine-based activation motif (ITAM) that is unique to the Nef protein of the acutely pathogenic simian immunodeficiency virus SIVsmPBj was studied in the context of two AIDS-inducing simian immunodeficiency virus molecular clones. NefY(+) variants of SIVagm9063-2
Objective: To study the clinical results and prognostic factors for allo-HSCT of Philadelphia chromosome-positive (Ph(+)) acute lymphoblastic leukemia (ALL) in complete remission (CR) in the era of tyrosine kinase inhibitors (TKI) . Methods: We performed a retrospective analysis of the
Pseudorabies virus (PRV), a swine alphaherpesvirus, is capable of causing viremia in vaccinated animals. Two mechanisms that may help PRV avoid recognition by the host immune system during this viremia are direct cell-to-cell spread in tissue and antibody-induced internalization of viral cell
Tyrosine kinase inhibitors (TKIs) are successfully used in clinic to treat chronic myeloid leukemia (CML). Our group previously described that CD4+ T cells from patients with CML on treatment with TKIs such as dasatinib were resistant to HIV-1 infection ex vivo. The main mechanism for this antiviral
A hallmark of pathogenic simian immunodeficiency virus (SIV) and human immunodeficiency virus (HIV) infections is the rapid and near-complete depletion of mucosal CD4(+) T lymphocytes from the gastrointestinal tract. Loss of these cells and disruption of epithelial barrier function are associated
Fibroblast growth factor receptor (FGFR) 3 is one of the four distinct membrane-spanning tyrosine kinases required for proper skeletal development. In fish, the role of FGFR3 is still unclear. In this article, we reveal that zebrafish FGFR3 is a negative regulator of interferon (IFN) production in
Dengue virus (DENV) and Zika virus (ZIKV) are mosquito-borne flaviviruses that cause severe illness after infection. Currently, there are no specific or effective treatments against DENV and ZIKV. Previous studies have shown that tyrosine kinase activities and signal transduction are involved in
The hypothesis has been advanced that the human systemic septic response is a function of the host and not of the type of infecting organism. Metabolic and physiologic data from five immunosuppressed transplant recipients with isolated cytomegaloviral sepsis and viremia were prospectively evaluated.
Deletion of Gly-720 and Tyr-721 from a highly conserved GYxxØ trafficking signal in the SIVmac239 envelope glycoprotein cytoplasmic domain, producing a virus termed ΔGY, leads to a striking perturbation in pathogenesis in rhesus macaques (Macaca mulatta). Infected macaques develop immune activation
The attenuated West Nile virus 25A strain (WN25A) was investigated for its neuroinvasive properties in B-cell-deficient (microMT) mice. After peripheral inoculation, WN25A caused fatal encephalitis in the majority of 6-8-week-old mice, characterized by a systemic infection with viraemia, moderate
A duck hepatitis B virus (DHBV) genome cloned from a domestic duck from the People's Republic of China has been sequenced and exhibits no variation in sequences known to be important in viral replication or generation of gene products. Intrahepatic transfection of a dimer of this viral genome into
BACKGROUND
In chronic hepatitis B, long-term use of alpha interferon is hampered by side effects, and long-term treatment with nucleos(t)ide analogues is burdened by drug-resistant mutants. We hypothesized that alternate rounds of lamivudine and alpha interferon might circumvent previous
The feline leukemia virus (FeLV) frequently causes death by predisposing the host to acute infections by other pathogens rather than by inducing leukemia. In a previous study, cats infected with FeLV were found to have prolonged homograft rejection responses but there was no evidence that the
The complete nucleotide sequence of the mRNA of the matrix (M) protein of vesicular stomatitis virus [New Jersey serotype, VSV(NJ)] was derived from a cDNA clone and mRNA. The mRNA is 758 nucleotides long (excluding polyadenylic acid) and encodes a protein of 229 amino acids. The predicted amino
