T lymphocytes play a pivotal role in the immune response during viral infections. In a murine model of experimental respiratory syncytial virus (RSV) infection, mice sensitized to either of the two major glycoproteins of RSV develop distinct patterns of cytokine secretion and lung inflammation upon subsequent RSV infection. Mice sensitized to RSV-G(More)
BACKGROUND Transmission of dengue viruses (DENV), the leading cause of arboviral disease worldwide, is known to vary through time and space, likely owing to a combination of factors related to the human host, virus, mosquito vector, and environment. An improved understanding of variation in transmission patterns is fundamental to conducting surveillance and(More)
Viral hemorrhagic diseases are a group of systemic viral infections with worldwide distribution and are significant causes of global mortality and morbidity. The hallmarks of viral hemorrhagic fevers are plasma leakage, thrombocytopenia, coagulopathy and hemorrhagic manifestations. The molecular mechanisms leading to plasma leakage in viral hemorrhagic(More)
BACKGROUND It is unclear whether dengue serotypes differ in their propensity to cause severe disease. We analyzed differences in serotype-specific disease severity in children presenting for medical attention in Bangkok, Thailand. METHODOLOGY/PRINCIPAL FINDINGS Prospective studies were conducted from 1994 to 2006. Univariate and multivariate logistic and(More)
BACKGROUND Based on spatiotemporal clustering of human dengue virus (DENV) infections, transmission is thought to occur at fine spatiotemporal scales by horizontal transfer of virus between humans and mosquito vectors. To define the dimensions of local transmission and quantify the factors that support it, we examined relationships between infected humans(More)
Surfactant protein (SP)-D gene targeted (SP-D-/-) and wild-type mice were infected with respiratory syncytial virus (RSV) by intratracheal instillation. Decreased clearance of RSV was observed in SP-D-/- mice. Deficiency of SP-D was associated with increased inflammation and inflammatory cell recruitment in the lung after infection. In vitro, SP-D bound(More)
BACKGROUND Dengue virus is endemic in tropical and sub-tropical resource-poor countries. Dengue illness can range from a nonspecific febrile illness to a severe disease, Dengue Shock Syndrome (DSS), in which patients develop circulatory failure. Earlier diagnosis of severe dengue illnesses would have a substantial impact on the allocation of health(More)
BACKGROUND Chikungunya virus (CHIKV) is a globally re-emerging arbovirus for which previous studies have indicated the majority of infections result in symptomatic febrile illness. We sought to characterize the proportion of subclinical and symptomatic CHIKV infections in a prospective cohort study in a country with known CHIKV circulation. (More)
adaptation. Various analyses are ongoing to answer questions about the route of transmission among seals and possible transmissibility to humans. Note added in proof: Zohari et al. also recently reported the involvement of avian influenza A(H10N7) virus in mass deaths of harbor seals in Sweden (Euro Surveill. et al. Human influenza A H5N1 virus related to a(More)
Revealing the patterns and determinants of the spread of dengue virus (DENV) at local scales is central to understanding the epidemiology and evolution of this major human pathogen. We performed a phylogenetic analysis of the envelope (E) genes of DENV-1, -2, -3, and -4 isolates (involving 97, 23, 5, and 74 newly collected sequences, respectively) sampled(More)
