Blood samples from umbilical CB, healthy young children, and healthy adults were used. 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, isotype-matched mAbs were used as controls. After 3 days of culture, both supernatants inmunoloia cells were tested for their ability to transmit the infection to epithelial cells.

J Allergy Clin Immunol ; The majority of children display a mild illness of the upper airways. The primer sets used for amplification were as follows: Cells were then washed, and infection was revealed at day 3 after infection by flow cytometry left or confocal microscopy middle panel, green: Nat Immunol ; 4: Then infection was detected by staining with the antihuman RSV mAb and quantified by flow cytometry.


Cell Lines HEp-2 cells human laryngeal carcinoma and Jurkat cells lymphoblastoid T-cell line were maintained in culture medium following the recommendations from the American Type Culture Collection. Statistical analyses were performed using GraphPad Prism 5. At day 1 after infection, cells were restimulated with anti-CD3 1.

J Infect Dis ; Potential conflicts of interest: Of note, 5 of these 6 patients required admission to the pediatric intensive care unit. Studies performed in mouse models have helped clarify the pathogenesis of infection.

When indicated, cells were challenged with ultraviolet-treated RSV. Respiratory syncytial virus RSV is the leading cause of lower respiratory disease in young infants [ 1—3 ].

Global and regional mortality from causes of death for 20 age groups in and The reasons for the contrasting results are unclear.


There are still relevant gaps in our understanding of pediatric RSV infection. Statistical analyses were based on at least events gated on the population of interest. Analysis of cytokine levels in nasal lavage fluid and PBMCs from infants with acute bronchiolitis due to RSV infection showed a type 2 T helper Th2 -biased response [ 30—32 ].

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. Innate immune dysfunction is associated with enhanced disease severity in infants with severe respiratory syncytial virus bronchiolitis.

Hence, we analyzed whether in vitro infection by RSV resulted in the loss of this cell subset. Whether T cells are permissive to RSV infection is unknown.

Increased number of T cells committed to IL-5 production after respiratory syncytial virus RSV infection of human mononuclear cells in vitro. In all experiments we used freshly isolated PBMCs. We excluded children with history of prematurity, immunodeficiency, congenital heart disease, and chronic conditions.
