Because the G protein of respiratory syncytial virus (RSV) has a CX3C chemokine motif that has been associated with the ability of RSV G protein to modulate the virus-induced host immune response, we examined whether therapeutic treatment with an anti-RSV G monoclonal antibody (mAb), 131-2G, that blocks the CX3C-associated activity of RSV G protein might(More)
Respiratory syncytial virus (RSV) is the most common cause of serious lower respiratory illness in infants and young children worldwide, making it a high priority for development of strategies for prevention and treatment. RSV can cause repeat infections throughout life, with serious complications in elderly and immunocompromised patients. Previous studies(More)
Respiratory syncytial virus (RSV) replication is primarily limited to the upper respiratory tract epithelium and primary, differentiated normal human bronchial epithelial cells (NHBE) have, therefore, been considered a good system for in vitro analysis of lung tissue response to respiratory virus infection and virus-host interactions. However, NHBE cells(More)
In 2013 in Tunisia, 3 persons in 1 family were infected with Middle East respiratory syndrome coronavirus (MERS-CoV). The index case-patient's respiratory tract samples were negative for MERS-CoV by reverse transcription PCR, but diagnosis was retrospectively confirmed by PCR of serum. Sequences clustered with those from Saudi Arabia and United Arab(More)
Respiratory syncytial virus (RSV) is a high priority target for vaccine development. One concern in RSV vaccine development is that a non-live virus vaccine would predispose for enhanced disease similar to that seen with the formalin inactivated RSV (FI-RSV) vaccine. Since a mAb specific to RSV G protein can reduce pulmonary inflammation and eosinophilia(More)
Real-time PCR has been developed to genotype measles virus (MV) isolates. MV strains circulating in epidemics in Gabon in 1984, Cameroon in 2001, Morocco in 2003, and France in 2004 were investigated. We developed a real-time amplification refractory mutation system PCR (RT-AMRS PCR) using SYBR green fluorescent dye. Six pairs of primers for RT-ARMS PCR(More)
Therapeutic options to control respiratory syncytial virus (RSV) are limited, thus development of new therapeutics is high priority. Previous studies with a monoclonal antibody (mAb) reactive to an epitope proximal to the central conserved region (CCR) of RSV G protein (mAb 131-2G) showed therapeutic efficacy for reducing pulmonary inflammation RSV(More)
Defective interfering viral particles have been reported as important determinants of the course of viral infection, and they can markedly temper the virulence of the infection. Here, we describe a simple method, based on limiting dilution, for the removal of defective interfering particles from RSV. This method results in a high-titer viral preparation(More)
We examined whether prophylactically administered anti-respiratory syncytial virus (anti-RSV) G monoclonal antibody (MAb) would decrease the pulmonary inflammation associated with primary RSV infection and formalin-inactivated RSV (FI-RSV)-enhanced disease in mice. MAb 131-2G administration 1 day prior to primary infection reduced the pulmonary inflammatory(More)
Therapeutic treatment with a non-neutralizing monoclonal antibody (mAb) (131-2G) specific to respiratory syncytial virus (RSV) G glycoprotein mediates virus clearance and decreases leukocyte trafficking and interferon gamma (IFN-gamma) production in the lungs of RSV-infected mice. Its F(ab')(2) component only mediates decreased leukocyte trafficking and(More)
