Avian pneumoviruses (APVs) are RNA viruses responsible for upper respiratory disease in poultry. Experimental infections are typically less severe than those observed in field cases. Previous studies with APV and Escherichia coli suggest this discrepancy is due to secondary agents. Field observations indicate APV infections are more severe with concurrent infection by Newcastle disease virus (N...
Respiratory syncytial virus (RSV) and human metapneumovirus (HMPV) are paramyxoviruses that are responsible for substantial human health burden, particularly in children and the elderly. The fusion (F) glycoproteins are major targets of the neutralizing antibody response and studies have mapped dominant antigenic sites in F. Here we grafted a major neutralizing site of RSV F, recognized by the ...
Negative-stranded virion RNA and oligonucleotide primers complementary to fusion (F) protein gene sequences were used to generate cDNA clones, revealing that the gene 5'-proximal to the F protein corresponded to the M2 (22K) gene, as in respiratory syncytial (RS) virus. The transcription start signal, GGGACAAGU, was identical to that of the F and matrix (M) proteins of turkey rhinotracheitis vi...
BACKGROUND Pulmonary edema plays a pivotal role in the pathophysiology of respiratory syncytial virus (RSV)-induced respiratory failure. In this study we determined whether treatment with TIP (AP301), a synthetic cyclic peptide that mimics the lectin-like domain of human TNF, decreases pulmonary edema in a mouse model of severe human RSV infection. TIP is currently undergoing clinical trials as...
Turkey rhinotracheitis (TRT) virus is a paramyxovirus associated with recent outbreaks of acute respiratory disease in turkeys. On morphological criteria it resembles the pneumoviruses more than the other members of the paramyxovirus family. In this communication we report the identification of five virus-induced polypeptides in TRT virus-infected BS-C-1 cells. The Mr of these polypeptides were...
The inflammatory response to respiratory virus infection can be complex and refractory to standard therapy. Lactobacilli, when targeted to the respiratory epithelium, are highly effective at suppressing virus-induced inflammation and protecting against lethal disease. Specifically, wild-type mice primed via intranasal inoculation with live or heat-inactivated Lactobacillus plantarum or Lactobac...
