  1. 11. Interplay between tick-borne encephalitis virus and the host innate immunity

    Författare :Chaitanya Kurhade; Anna Överby Wernstedt; Nelson Gekara; Helen Lazear; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Virology; Flavivirus; IPS-1; Interferon; Viperin; mikrobiologi; Microbiology;

    Sammanfattning : Flaviviruses are important emerging and re-emerging arthropod-borne pathogens that cause significant morbidity and mortality in humans. It consists of globally distributed human pathogens such as tick-borne encephalitis virus (TBEV), West Nile virus (WNV), Japanese encephalitis virus (JEV), yellow fever virus (YFV), dengue virus (DENV), and Zika virus (ZIKV).

  3. 12. Cervical cancer studies on prevention and treatment

    Författare :Lotten Darlin; Lund Obstetrik och gynekologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cervical cancer; human papilloma virus; HPV; screening; HPV test; self-sampling; sentinel node;

    Sammanfattning : Cervical cancer is the fourth most common reason for cancer death amongst women worldwide, with 500 000 new cases every year. Most of these women live in developing countries. Cervical screening programs can reduce the incidence by 50%, but are not common in the developing world. LÄS MER

  4. 13. Evolution of HIV-1 coreceptor use in relation to pathogenesis

    Författare :Ingrid Karlsson; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; Medicine human and vertebrates ; RANTES; higly active antiretroviral therapy; pathogenesis; lymphoid tissue; cehmokine receptor; biological phenotype; coreceptor; HIV-1; evolution;

    Sammanfattning : HIV-1 uses the coreceptors CCR5 and/or CXCR4 in addition to CD4 to enter the host cell. CCR5-using HIV-1 (R5 phenotype) appears to transmit infection and usually dominates the early stages of disease. LÄS MER

  5. 14. Physics of Viral Infectivity: Energetics of Genome Ejection

    Författare :Meerim Jeembaeva; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microfluidics.; differential scanning calorimetry; capsid; Key words: phage; osmotic suppression; DNA ejection; isothermal titration calorimetry; enthalpy;

    Sammanfattning : All viruses that infect bacteria, plant, or animal cells involve a genome (RNA or DNA) that is encapsidated by a rigid protein shell. After delivery of the viral genome into the host cell, new capsid proteins, which are encoded by viral DNA or RNA, are expressed and self-assembled into new viral capsids. LÄS MER

  7. 15. Dynamics of HIV coreceptors and their utilization by plasma and cerebrospinal fluid HIV-1 isolates

    Författare :Ulf Karlsson; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : HIV-1 infection of CD4+ immune cells requires the assistance of cellular coreceptors. The regulation of these receptors is highly dynamic. In addition to the major coreceptors, CCR5 and CXCR4, several alternative coreceptors mediate entry for selected HIV isolates in vitro, although their role in vivo is yet to be established. LÄS MER
