  1. 6. Virus tropism and neutralization response in SIV infection

    Författare :Anna Laurén; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Naturvetenskap; Natural science; Medicin människa och djur ; Medicine human and vertebrates ; HIV; SIV; mode of CCR5 use; CD4-independence; macrophage tropism; coreceptor use; neutralization; evolution; pathogenesis;

    Sammanfattning : Simian immunodeficiency virus (SIV) infections in macaques are commonly used as models to study the pathogenesis of human immunodeficiency virus (HIV). Both SIV and HIV normally use the CD4 receptor and an additional coreceptor for cell entry. The most common coreceptors used by HIV are CCR5 and CXCR4. LÄS MER

  3. 7. Cellular receptors for species B adenoviruses

    Författare :Marko Marttila; Niklas Arnberg; Göran Wadell; Tomas Bergström; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adenovirus; CD46; CD80; CD86; Species B; Receptor; Internalization; Infection; Tropism; Virology; Virologi;

    Sammanfattning : Adenoviruses belong to the most common human pathogens. The severity of infection varies greatly, from subclinical to lethal, depending on the virus type and immune status of the infected host. The 51 known human adenovirus serotypes are divided into six species (A-F) based on characteristics such as tropism. LÄS MER

  4. 8. Tissue tropism among group A streptococci - importance of bacteria associated proteolytic activity

    Författare :Mikael Dag Svensson; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cysteine protease; plasminogen; M protein; Streptococcus pyogenes; tissue tropism; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Group A streptococcus (GAS) is one of the most common of bacterial pathogens infecting humans, frequently causing throat and skin infection. Some GAS strains have surface-expressed virulence factors called M proteins that bind human plasminogen with high affinity. LÄS MER

  5. 9. Cellular receptors for viruses with ocular tropism

    Författare :Emma C Nilsson; Niklas Arnberg; Eric J Kremer; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adenovirus; picornavirus; receptors; antivirals; Virology; Virologi; molekylärbiologi; Molecular Biology; Infectious Diseases; infektionssjukdomar; mikrobiologi; Microbiology;

    Sammanfattning : Several viruses from different virus families are known to cause ocular infections, e.g. members of the Adenoviridae, Picornaviridae and the Herpesviridae families. These infections are spread by contact and in the case of adenoviruses (Ads) and picornaviruses they are also highly contagious. LÄS MER

  7. 10. Adenovirus species B: receptors, tropism and hematopoietic cells

    Författare :Anna Segerman; Göran Wadell; Ya-Fang Mei; Urs Greber; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; Adenovirus; Species B; hematopoietic; Mikrobiologi; Microbiology; immunology; infectious diseases; Mikrobiologi; immunologi; infektionssjukdomar; medicinsk virologi; Medical Virology;

    Sammanfattning : At present, the human adenoviruses (Ads) comprise 51 members, which have been classified into six species (A to F). In general, adenovirus (Ad) tissue tropism or disease patterns vary according to species, although adenoviruses from different species can sometimes cause the same symptoms. LÄS MER
