ABSTRACT Given the critical role of pattern recognition receptors (PRRs) in acid nucleic recognition in the initiation of innate immunity and the orchestration of adaptive immunity, the aim of this study was to determine whether any heterogeneity of PRR expression in the airway tracts of infants with respiratory syncytial virus (RSV) infection might explain the broad clinical spectrum of RSV-associated bronchiolitis in infants. For this purpose, the levels of melanoma differentiation-associated protein-5 (MDA-5), retinoic acid inducible gene-1 (RIG-1), and Toll-like receptor 3 (TLR-3), TLR-7, TLR-8, and TLR-9 mRNAs were evaluated, using TaqMan quantitative reverse transcription-PCR, in cells from nasopharyngeal washes collected from 157 infants suffering from acute bronchiolitis whether or not they were associated with respiratory viruses. High interindividual variability was observed in both virus-positive and -negative infants; however, the relative gene expression levels of MDA-5, RIG-1, TLR-7, and TLR-8 were significantly higher in the virus-infected group, whereas the expression levels of TLR-3 and TLR-9 were not significantly different. The differences in the gene expression of MDA-5, RIG-1, TLR-7, and TLR-8 were more evident in infants with RSV infection than in those with bocavirus or rhinovirus infection. In RSV-infected infants, PRR-mRNA levels also were analyzed in relation to interferon protein levels, viral load, clinical severity, days of hospitalization, age, and body weight. A significant positive correlation was observed only between RSV viral load and RIG-1 mRNA levels. These findings provide the first direct evidence that, in infants with respiratory virus-associated bronchiolitis, especially RSV, there are substantial changes in PRR gene expression; this likely is an important determinant of the clinical outcome of bronchiolitis.

We investigated the effects of fermented potato protein (FPP), supplied through drinking water, on growth performance of broiler chickens. A total of 288 male broiler chickens were divided into two groups: a control group and an experimental group supplemented with 0.01% FPP in drinking water. The FPP group had a significantly higher BWG and ADG (P less than 0.01) and significantly improved FCR (Pless than 0.05). The percentage of breast was significantly higher (P less than 0.05) in fermented potato protein (FPP) group. The FPP group had an increased villus height (P less than 0.05) in duodenum and jejunum. Expression of IGF-1 gene in the liver was significantly higher in the FPP group than in the control group (P less than 0.05), whereas GHR gene expression did not differ between the groups at 37 days. This study suggests that FPP supplementation in drinking water improves growth performance of broiler chickens by stimulating IGF-1 gene expression in the liver and improving the intestinal morphology.
