  1. 1. The role of the type I interferons and viperin during neurotropic flavivirus infection

    Author : Richard Lindqvist; Anna Överby Wernstedt; Daniel Ruzek; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TBEV; Flavivirus; Interferon; Neurotropic; Viperin;

    Abstract : Flaviviruses are globally distributed pathogens that cause millions of human infections annually. One of the most detrimental outcomes of flavivirus infection is encephalitis, which is caused by neurotropic flaviviruses such as West Nile virus (WNV), Japanese encephalitis virus (JEV), and Tick-borne encephalitis virus (TBEV).

  2. 2. The Origin of the Genus Flavivirus and the Ecology of Tick-Borne Pathogens

    Author : John H.-O. Pettersson; Thomas Jaenson; Sven Bergström; Kenneth Nilsson; Mikael Thollesson; Per-Eric Lindgren; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Flavivirus; Virus dating; Molecular dating; Biogeography; Ixodes ricinus; Minimum infection rate; TBE; Tick-borne encephalitis virus; Rickettsia helvetica; Anaplasma phagocytophilum; Infection prevalence; RT-PCR; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Abstract : The present thesis examines questions related to the temporal origin of the Flavivirus genus and the ecology of tick-borne pathogens. In the first study, we date the origin and divergence time of the Flavivirus genus. It has been argued that the first flaviviruses originated after the last glacial maximum. READ MORE

    Abstract : Flaviviruses are found all over the world and affect and infect millions of people every year. Flavivirus infection can lead to severe clinical outcomes resulting in neuronal damages e.g. Tick-borne encephalitis virus (TBEV), or severe hemorrhagic fevers e. READ MORE

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

    Abstract : 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).

    Abstract : The recent emergence of a number of new viral diseases as well as the re-emergence of tuberculosis (TB), indicate an urgent need for new drugs against viral and bacterial infections.Coronavirus nsp1 has been shown to induce suppression of host gene expression and interfere with host immune response.
