Cells were then washed and cultured for 3 days in the presence of Ribavirin.
Introduccion a La Inmunologia Humana/ Introduction to Human Immunology
Respiratory syncytical virus-induced chemokine expression in the lower airways: Written informed consent was obtained from all donors or legal guardians.
Baseline characteristics of each patient are shown in Table 1. Recognized risk factors for severe RSV infection include prematurity, young age, congenital heart disease, Down syndrome, and chronic lung diseases [ 46 ].
Primary human mDC1, inmunoogia, and pDC dendritic cells are differentially infected and activated by respiratory syncytial virus. Assays were performed in duplicates. Further studies involving children with mild illness are required to test this hypothesis.
Then HEp-2 infection was analyzed by flow cytometry. N Engl J Med ; We have recently reported that RSV infection in young infants who required hospitalization induced a dramatic and prolonged reduction in the frequency of peripheral blood Tregs [ 13 ]. We excluded children with history of prematurity, immunodeficiency, congenital heart disease, and chronic conditions.
They could be explained by differences in the antibodies used to analyze the expression of RSV antigens. Primer sets yielded a single product of the correct size.

Considering the strong inhibition of IL-2 production induced by RSV infection, we then looked at the expression of CD25, the alpha chain of the high-affinity IL-2 receptor, expressed by activated T cells. Inmunologla 3 days of culture, both supernatants and cells were tested for their ability to transmit the infection to epithelial cells. Productive infection of isolated human alveolar macrophages by respiratory syncytial virus.
Disease severity was assessed by applying a clinical disease severity score CDSS based on the modified Tal score, which classified patients gefvner having mild 0—4moderate 5—8or severe 9—12 RSV bronchiolitis at the time of sampling [ 1415 ]. Hence, we analyzed whether in vitro infection by RSV resulted in the loss of this cell subset. Clinical and epidemiologic features of respiratory syncytial virus.
J Allergy Clin Immunol ; Challenges in estimating RSV-associated mortality rates. The authors thank Federico Fuentes for his technical assistance in the studies performed by confocal microscopy.
Virus was propagated and titrated on HEp-2 cells, as previously described [ 1617 ]. Garrahan for their efforts in enrolling study subjects. The analysis of cytokine production was performed in the gate of live cells based on their forward and side scatter parameters.
Pediatr Infect Dis J ; Increased number of T cells committed to IL-5 production after respiratory gefffner virus RSV infection of human mononuclear cells in vitro. Impaired antibody-mediated protection and defective IgA B-cell memory in experimental infection of adults with respiratory syncytial virus. To inactivate RSV, the virus was exposed for 30 minutes to ultraviolet light, as previously described [ 18 ]. There are still relevant gaps in our understanding of pediatric RSV infection.
As expected, infection levels were lower in Jurkat cells compared with the epithelial cell line Inmunolgia Figure 1A. The authors also thank Dr Mark E.
Statistical analyses were based on at least events gated on the population of interest. No changes in the production of IL-5 and IL were detected not shown. J Clin Invest ; Received Nov 12; Accepted Jan At day 1 after infection, cells were restimulated with anti-CD3 1.
Studies performed in mouse models have helped clarify the pathogenesis of infection. Baseline characteristics of each RSV-infected patient are shown in Table 1.

Later, infection was revealed by flow cytometry.
