      Objectives Elderly are an understudied, high-risk group vulnerable to severe COVID-19. We comprehensively analyzed the durability of humoral and cellular immune responses after BNT162b2 vaccination and SARS-CoV-2 infection ...

    • Matrix M Adjuvanted H5N1 Vaccine Elicits Broadly Neutralizing Antibodies and Neuraminidase Inhibiting Antibodies in Humans That Correlate With In Vivo Protection 

      Zhou, Fan; Hansen, Lena; Pedersen, Gabriel Kristian; Grødeland, Gunnveig; Cox, Rebecca Jane (Journal article; Peer reviewed, 2021)
      The highly pathogenic avian influenza H5N1 viruses constantly evolve and give rise to novel variants that have caused widespread zoonotic outbreaks and sporadic human infections. Therefore, vaccines capable of eliciting ...

    • A rapid antibody screening haemagglutination test for predicting immunity to SARS-CoV-2 variants of concern 

      Ertesvåg, Nina Urke; Xiao, Julie; Zhou, Fan; Ljostveit, Sonja; Sandnes, Helene Heitmann; Lartey, Sarah; Sævik, Marianne; Hansen, Lena; Madsen, Anders; Mohn, Kristin Greve-Isdahl; Fjelltveit, Elisabeth Berg; Olofsson, Jan Stefan; Tan, Tiong Kit; Rijal, Pramilia; Schimanski, Lisa; Øyen, Siri; Brokstad, Karl Albert; Dunachie, Susanna; Jämsén, Anni; James, William S.; Harding, Adam C.; Harvala, Heli; Nguyen, Dung; Roberts, David; Patel, Monika; Gopal, Robin; Zambon, Maria; Wei, Leiyan; Gilbert-Jaramillo, Javier; Knight, Michael L.; Vaughan-Jackson, Alun; Dupont, Maeva; Lamikanra, Abigail A.; Klennerman, Paul; Townsend, Alain; Tøndel, Camilla; Kuwelker, Kanika; Blomberg, Bjørn; Bredholt, Geir; Onyango, Therese Bredholt; Vahokoski, Juha; Bansal, Amit; Trieu, Mai Chi; Amdam, Håkon; Akselsen, Per Espen; Skorge, Trude Duelien; Okkenhaug, Liv Heiberg; Linchausen, Dagrun Waag; Langeland, Nina; Cox Brokstad, Rebecca Jane (Journal article; Peer reviewed, 2022)
      Background: Evaluation of susceptibility to emerging SARS-CoV-2 variants of concern (VOC) requires rapid screening tests for neutralising antibodies which provide protection. Methods: Firstly, we developed a receptor-binding ...

    • Repeated Influenza Vaccination Boosts and Maintains H1N1pdm09 Neuraminidase Antibody Titers 

      Hansen, Lena; Zhou, Fan; Amdam, Håkon; Trieu, Mai Chi; Cox, Rebecca Jane (Journal article; Peer reviewed, 2021)
      Antibodies to influenza surface protein neuraminidase (NA) have been found to reduce disease severity and may be an independent correlate of protection. Despite this, current influenza vaccines have no regulatory requirements ...

    • Risk assessment and antibody responses to SARS-CoV-2 in healthcare workers 

      Bansal, Amit; Trieu, Mai Chi; Mohn, Kristin Greve-Isdahl; Madsen, Anders; Olofsson, Jan Stefan; Sandnes, Helene Heitmann; Sævik, Marianne; Søyland, Hanne; Hansen, Lena; Onyango, Therese Bredholt; Tøndel, Camilla; Brokstad, Karl Albert; Syre, Heidi; Riis, Åse Garløv; Langeland, Nina; Cox, Rebecca Jane (Journal article; Peer reviewed, 2023)
      Background: Preventing infection in healthcare workers (HCWs) is crucial for protecting healthcare systems during the COVID-19 pandemic. Here, we investigated the seroepidemiology of SARS-CoV-2 in HCWs in Norway with ...

    • Strategies for improving Influenza vaccines: insights from the Influenza A H1N1 and SARS-CoV-2 pandemics 

      Hansen, Lena (Doctoral thesis, 2022-09-23)
      Influensa er et luftveisvirus som kan forårsake alvorlig sykdom og under stadig forandring (drift). Dagens influensavaksiner gir begrenset beskyttelse mot slike driftede influensavirus. Dette fører til at vaksinesammensetningen ...

    • Upregulated PDK4 expression is a sensitive marker of increased fatty acid oxidation 

      Pettersen, Ina Katrine Nitschke; Tusubira, Deusdedit; Ashrafi, Hanan; Dyrstad, Sissel Elisabeth; Hansen, Lena; Liu, Xiao-Zheng; Hodneland, Linn I.; Løvsletten, Nils Gunnar; Berge, Kjetil; Wergedahl, Hege; Bjørndal, Bodil; Fluge, Øystein; Bruland, Ove; Rustan, Arild; Halberg, Nils; Røsland, Gro Vatne; Berge, Rolf Kristian; Tronstad, Karl Johan (Peer reviewed; Journal article, 2019)
      Fatty acid oxidation is a central fueling pathway for mitochondrial ATP production. Regulation occurs through multiple nutrient- and energy-sensitive molecular mechanisms. We explored if upregulated mRNA expression of the ...
