Respiratory syncytial virus G and/or SH glycoproteins modify CC and CXC chemokine mRNA expression in the BALB/c mouse.

چکیده
Chemokine mRNA expression by pulmonary leukocytes following infection of BALB/c mice with two strains of respiratory syncytial virus (RSV) and one strain of parainfluenza virus type 3 (PIV-3) was determined. The results suggest that RSV G and/or SH proteins inhibit early MIP-1alpha, MIP-1beta, MIP-2, MCP-1, and IP-10 mRNA expression. TCA-3 mRNA expression was found to be increased during PIV-3 infection.

Enhanced disease and pulmonary eosinophilia associated with formalin-inactivated respiratory syncytial virus vaccination are linked to G glycoprotein CX3C-CX3CR1 interaction and expression of substance P.
Vaccination with formalin-inactivated respiratory syncytial virus (FI-RSV) vaccine or RSV G glycoprotein results in enhanced pulmonary disease after live RSV infection. Enhanced pulmonary disease is characterized by pulmonary eosinophilia and is associated with a substantial inflammatory response. We show that the absence of the G glycoprotein or G glycoprotein CX3C motif during FI-RSV vaccinat...
متن کاملProduction of chemokines in the lungs of infants with severe respiratory syncytial virus bronchiolitis.
BACKGROUND Respiratory syncytial virus (RSV) bronchiolitis in infants is characterized by a massive neutrophilic infiltrate into the airways. Chemokines direct migration of leukocytes and contribute to the pathogenesis of RSV disease. However, little is known about pulmonary chemokine responses to RSV in humans. Our aim was to characterize the production of chemokines in the lungs of infants wi...
متن کاملIn vitro expression of full-length and truncated bovine respiratory syncytial virus G proteins and their antibody responses in BALB/c mice.
Bovine respiratory syncytial virus (BRSV) is a primary cause of lower respiratory tract disease in calves. Protection is incomplete following vaccination or natural infection, as re-infections are common. The objectives of this study were to create plasmid DNA constructs encoding the full-length, secreted, or conserved region of the BRSV G glycoprotein, and to compare and evaluate their express...
متن کاملExpression of respiratory syncytial virus-induced chemokine gene networks in lower airway epithelial cells revealed by cDNA microarrays.
The Paramyxovirus respiratory syncytial virus (RSV) is the primary etiologic agent of serious epidemic lower respiratory tract disease in infants, immunosuppressed patients, and the elderly. Lower tract infection with RSV is characterized by a pronounced peribronchial mononuclear infiltrate, with eosinophilic and basophilic degranulation. Because RSV replication is restricted to airway epitheli...
متن کاملThe purification of four respiratory syncytial virus proteins and their evaluation as protective agents against experimental infection in BALB/c mice.
The fusion (F) glycoprotein, large glyco- (G) protein, phospho- (P) protein and 22K protein of respiratory syncytial (RS) virus A2 strain were purified by a combination of immunoaffinity adsorption and preparative SDS-PAGE. All four proteins elicited serum antibody in mice after repeated inoculation in adjuvant, although the magnitude of the response as measured by ELISA varied from mouse to mo...
