• Apicomplexan actin polymerization depends on nucleation 

      Kumpula, Esa-Pekka; Pires, Isa; Lasiwa, Davki; Piirainen, Henni; Bergmann, Ulrich; Vahokoski, Juha; Kursula, Inari (Peer reviewed; Journal article, 2017-09-22)
      Filamentous actin is critical for apicomplexan motility and host cell invasion. Yet, parasite actin filaments are short and unstable. Their kinetic characterization has been hampered by the lack of robust quantitative ...
    • Biophysical analysis of Plasmodium falciparum Hsp70-Hsp90 organising protein (PfHop) reveals a monomer that is characterised by folded segments connected by flexible linkers 

      Makumire, Stanley; Zininga, Tawanda; Vahokoski, Juha; Kursula, Inari; Shonhai, Addmore (Journal article; Peer reviewed, 2020)
      Plasmodium falciparum causes the most lethal form of malaria. The cooperation of heat shock protein (Hsp) 70 and 90 is thought to facilitate folding of select group of cellular proteins that are crucial for cyto-protection ...
    • Durable immune responses after BNT162b2 vaccination in home-dwelling old adults 

      Hansen, Lena; Brokstad, Karl Albert; Bansal, Amit; Zhou, Fan; Bredholt, Geir; Onyango, Therese Bredholt; Sandnes, Helene Heitmann; Elyanow, Rebecca; Madsen, Anders; Trieu, Mai Chi; Sævik, Marianne; Søyland, Hanne; Olofsson, Jan Stefan; Vahokoski, Juha; Ertesvåg, Nina Urke; Fjelltveit, Elisabeth Berg; Shafiani, Shahin; Tøndel, Camilla; Chapman, Heidi; Kaplan, Ian; Mohn, Kristin Greve-Isdahl; Langeland, Nina; Cox, Rebecca Jane (Journal article; Peer reviewed, 2023)
      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 ...
    • Genetic diversity in the metronidazole metabolism genes nitroreductases and pyruvate ferredoxin oxidoreductases in susceptible and refractory clinical samples of Giardia lamblia 

      Saghaug, Christina Skår; Gamlem, Astrid Leinebø; Hauge, Kirsti Brugrand; Vahokoski, Juha; Klotz, Christian; Aebischer, Toni; Langeland, Nina; Hanevik, Kurt (Journal article; Peer reviewed, 2023)
      The effectiveness of metronidazole against the tetraploid intestinal parasite Giardia lamblia is dependent on its activation/inactivation within the cytoplasm. There are several activating enzymes, including pyruvate ...
    • High-resolution structures of malaria parasite actomyosin and actin filaments 

      Vahokoski, Juha; Calder, Lesley J.; Moreno, Andrea Johana Lopez; Molloy, Justin E.; Kursula, Inari; Rosenthal, Peter B. (Journal article; Peer reviewed, 2022-04-04)
      Malaria is responsible for half a million deaths annually and poses a huge economic burden on the developing world. The mosquito-borne parasites (Plasmodium spp.) that cause the disease depend upon an unconventional ...
