| th1 and th2 cytokine expression in nasopharyngeal secretions during acute bronchiolitis in children younger than two years old. | we characterised the t helper cytokine profiles on the surface of nasal mucosa of children with acute bronchiolitis caused by respiratory syncytial virus, parainfluenza virus, influenza virus, adenovirus, or without any viral identification, in order to examine whether these viral types modified cytokine responses. as an additional objective we sought to determine if t helper polarisation was associated with other demographic and environmental factors. | 2011 | 20685025 |
