    Prof. Akiko Iwasaki sur Twitter :

    “Are you confused about the role of type I #interferons (IFN) in #SARS_CoV_2 infection? Here is my speculation on what makes IFN-I helpful vs. harmful in #COVID19 patients - it comes down to timing and dose. A short thread. All figures made by BioRender & @annsea_park (1/n)” / Twitter

    Prof. Akiko Iwasaki sur Twitter : “In the best case scenario, a rapid and robust induction of IFN-I should result in viral control and mild disease. This may happen in young people, or with low viral exposure settings. For a discussion we wrote, please read this. (2/n)” / Twitter

    Prof. Akiko Iwasaki sur Twitter : “In older adults or after high dose viral exposure, impaired IFN response early during infection results in enhanced viral replication, and prolonged levels of IFN-I and IFN-III responses that could result in pathological consequences and severe disease.

    Prof. Akiko Iwasaki sur Twitter :
    “Not all studies show this pattern. Here is a study that showed lower IFN-I levels in more severe COVID patients. It would be interesting to understand this difference. (5/n) ▻https://t.co/0pFi0VebYd” / Twitter

    Prof. Akiko Iwasaki sur Twitter : “In the setting of host genetic mutations in viral sensors, signaling molecules, adaptors, transcription factors; or in older people with neutralizing antibodies to IFN-I, little to no IFN-I is available. Uncontrolled virus replication can lead to very severe COVID-19. (6/n)” / Twitter

    Prof. Akiko Iwasaki sur Twitter : “Finally, recombinant IFN therapy, especially given early during infection, can shut down viral replication and promote recovery. Further, prophylactic treatment with rIFN might be useful in high risk groups. (8/n)” / Twitter
