25. Emergence of hantaviral disease in the southwestern United States.
Hantaviruses are parasites of small mammals, predominantly peridomestic and commensal rodents. They have a worldwide distribution. Hantavirus-related illness occurs in rural areas where humans come into contact with rodents. In most cases human infection is manifested by one of a variety of acute illnesses involving hemorrhagic fever and renal disease. In Ma

26. Active and Passive Vaccination against Hantavirus Pulmonary Syndrome with Andes Virus M Genome Segment-Based DNA Vaccine
Hantavirus pulmonary syndrome (HPS) is a rapidly progressing human disease with one of the highest case fatality rates (30 to 50%) of any acute viral disease known. There are no vaccines, effective antiviral drugs, or immunologics to prevent or treat HPS. In an attempt to develop HPS medical countermeasures, we constructed an expression plasmid, pWRG/AND-M,

27. β3 integrins mediate the cellular entry of hantaviruses that cause respiratory failure
Newly emerged hantaviruses replicate primarily in the pulmonary endothelium, cause acute platelet loss, and result in hantavirus pulmonary syndrome (HPS). We now report that specific integrins expressed on platelets and endothelial cells permit the cellular entry of HPS-associated hantaviruses. Infection with HPS-associated hantaviruses, NY-1 and Sin Nombre

28. Hantavirus Nucleocapsid Protein Is Expressed as a Membrane-Associated Protein in the Perinuclear Region
Black Creek Canal virus (BCCV) is a New World hantavirus which is associated with hantavirus pulmonary syndrome. We have examined the site of expression of the BCCV nucleocapsid protein (NBCCV) in the absence of BCCV glycoproteins and found that the majority of the protein is localized to the Golgi region. Immunofluorescence analysis of BHK21 cells expressin

29. Elevated Generation of Reactive Oxygen/Nitrogen Species in Hantavirus Cardiopulmonary Syndrome
Hantavirus cardiopulmonary syndrome (HCPS) is a life-threatening respiratory disease characterized by profound pulmonary edema and myocardial depression. Most cases of HCPS in North America are caused by Sin Nombre virus (SNV), which is carried asymptomatically by deer mice (Peromyscus maniculatus). The underlying pathophysiology of HCPS is poorly understood

30. Pathogenic and nonpathogenic hantaviruses differentially regulate endothelial cell responses
Hantaviruses cause two human diseases: hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS). Hantaviruses infect human endothelial cells but cause little or no damage to the infected endothelium. We analyzed with Affymetrix DNA Arrays (Santa Clara, CA) the endothelial cell transcriptional responses directed by hantaviruses ass

31. Genetic Diversity, Distribution, and Serological Features of Hantavirus Infection in Five Countries in South America
Since 1995 when the first case of hantavirus pulmonary syndrome (HPS) was reported in Patagonia, there have been more than 400 cases of HPS reported in five countries in South America. The first case of HPS was associated with Andes (AND) virus. In this study, we report on the genetic diversity, geographical distribution, and serological features of hantavir

32. Human Memory Cytotoxic T-Lymphocyte (CTL) Responses to Hantaan Virus Infection: Identification of Virus-Specific and Cross-Reactive CD8+ CTL Epitopes on Nucleocapsid Protein
Hantaan virus, the prototypic member of the Hantavirus genus, causes hemorrhagic fever with renal syndrome in humans. We examined the human memory T-lymphocyte responses of three donors who had previous laboratory-acquired infections with Hantaan virus. We demonstrated virus-specific responses in bulk cultures of peripheral blood mononuclear cells (PBMC) fro

33. Polarized entry and release in epithelial cells of Black Creek Canal virus, a New World hantavirus.
Black Creek Canal (BCC) virus is a newly identified hantavirus from Florida which is carried by the cotton rat (Sigmodon hispidus) and is associated with hantavirus pulmonary syndrome (HPS). We have investigated the interaction of BCC virus with polarized epithelial cells to examine whether entry and release of this virus occur at specific plasma membrane do

34. Complete genetic characterization and analysis of isolation of Sin Nombre virus.
This study reports completion of the genetic characterization of the entire genome of Sin Nombre (SN) virus (NMH10) detected in autopsy tissues from a patient who died of hantavirus pulmonary syndrome (HPS). The large (L) genome segment was found to be 6,562 nucleotides in length and encoded a putative L polymerase that was 2,153 amino acids in length. No ev

35. Cross-Protection against Challenge with Puumala Virus after Immunization with Nucleocapsid Proteins from Different Hantaviruses
Hantaviruses are rodent-borne agents that cause hemorrhagic fever with renal syndrome or hantavirus pulmonary syndrome in humans. The nucleocapsid protein (N) is relatively conserved among hantaviruses and highly immunogenic in both laboratory animals and humans, and it has been shown to induce efficient protective immunity in animal models. To investigate t

36. Tyrosine Residues Direct the Ubiquitination and Degradation of the NY-1 Hantavirus G1 Cytoplasmic Tail
The hantavirus G1 protein contains a long C-terminal cytoplasmic tail of 142 residues. Hantavirus pulmonary syndrome-associated hantaviruses contain conserved tyrosine residues near the C terminus of G1 which form an immunoreceptor tyrosine activation motif (ITAM) and interact with Src and Syk family kinases. During studies of the G1 ITAM we observed that fu
