Quantification of IL-2 in cell supernatants was performed by enzyme-linked immunosorbent assay BD Biosciences. Recognized risk factors for severe RSV infection include prematurity, young age, congenital imnunologia disease, Down syndrome, and chronic lung diseases [ 46 ]. No donors had any hereditary disorder, hematologic abnormalities, or infectious complications. J Immunol ; Nat Med ; 8: Global and regional mortality from causes of death for 20 age groups in and Productive infection of isolated human alveolar macrophages by respiratory syncytial virus.

Cytokine tumor necrosis factor, IL-6, and IL-8 production by respiratory syncytial virus-infected human alveolar macrophages. Chang J, Braciale TJ. Lower gdffner tract infection caused by respiratory syncytial virus: 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 ]. In all cases, infection was revealed after 3 days inmuonlogia culture by flow cytometry.

Primary human mDC1, mDC2, and pDC dendritic cells are differentially infected and activated by respiratory syncytial virus.

Depletion of circulating regulatory T cells during severe respiratory syncytial virus infection in young children. Protective T cell immunity against respiratory syncytial virus is efficiently induced by recombinant BCG.


We excluded children with history of prematurity, immunodeficiency, congenital heart disease, and chronic conditions. The reasons for the contrasting results are unclear.

Studies performed in mouse models have helped clarify the pathogenesis of infection. Received Nov 12; Accepted Jan Increased number of T cells committed to IL-5 production after respiratory syncytial virus RSV infection of human mononuclear cells in vitro. Representative gevfner are shown in A and B left. Pediatr Infect Dis J ; J Virol ; In all experiments we used freshly isolated PBMCs.

Studies performed in murine models have shown that RSV infects B lymphocytes, but not T lymphocytes [ 27 ]. The majority of children display a mild illness of the upper airways. Nat Rev Immunol ; To inactivate RSV, the virus was exposed for 30 minutes to ultraviolet light, as previously described [ 18 ]. The analysis of cytokine production was performed in the gate of live cells based on their forward and side scatter parameters. Respiratory syncytial virus infection was analyzed in the gate of live cells based on their forward and side scatter parameters.

Differentiation and immune function of human dendritic cells following infection by respiratory syncytial virus. They could be inmunoloyia by differences in the antibodies used to analyze the expression of RSV antigens. There are still relevant gaps in our understanding of pediatric RSV infection.

Respiratory syncytial virus RSV is the leading cause of lower respiratory disease in young infants [ 1—3 ]. Curr Top Microbiol Immunol ; Disease severity was analyzed using standard criteria, as described in the Materials and Methods. Garrahan for their efforts in geffnef study subjects. Microbial infection-induced expansion of effector T cells overcomes the suppressive effects of regulatory T cells via an IL-2 deprivation mechanism.


Whether T gecfner are permissive to RSV infection is unknown.

N Engl J Med ; This article has been cited by other articles in PMC. Cord blood samples were obtained from umbilical cord veins at birth. Mortality due to respiratory syncytial virus burden and risk factors. The burden of respiratory syncytial virus infection in young children.

Impaired antibody-mediated protection and defective IgA B-cell memory in experimental infection of adults with respiratory syncytial virus. After 3 days of culture, both supernatants and cells were tested for their ability to transmit the infection to epithelial cells.

J Exp Med ; Disease severity was assessed by applying a clinical disease severity score CDSS based on the modified Tal score, which classified patients as having mild 0—4moderate 5—8or severe 9—12 RSV bronchiolitis at the time of sampling [ 1415 ].

Curr Opin Infect Dis ; 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.
