Thymus activity measured by T-cell receptor excision circles in patients with different severities of respiratory syncytial virus infection

BACKGROUND Respiratory syncytial virus (RSV) infection is an important cause of hospitalization in previously healthy infants. Immunological mechanisms predisposing infants to severe disease are poorly understood. Early biomarkers for disease severity may assist clinical decisions. We investigated T-cell receptor excision circles (TREC), episomal DNA made during thymic T-cell receptor rearrange...

Bovine respiratory syncytial virus infection.

Bovine respiratory syncytial virus (BRSV) belongs to the pneumovirus genus within the family Paramyxoviridae and is a major cause of respiratory disease in young calves. BRSV is enveloped and contains a negative sense, single-stranded RNA genome encoding 11 proteins. The virus replicates predominantly in ciliated respiratory epithelial cells but also in type II pneumocytes. It appears to cause ...

Helper T cell recognition of respiratory syncytial virus in mice.

In this study we aimed to define the protein and viral subtype specificities of helper Th cells to respiratory syncytial virus (RSV). BALB/c mice were primed by infection with RSV, or with vaccinia viruses (VV) containing genes encoding several individual RSV proteins. Priming for Th cell memory was assayed by stimulating spleen cells in vitro with different RSV isolates and measuring RSV-speci...
