Ученые выяснили, почему пациенты с COVID-19 теряют обоняние

Международная группа ученых под руководством нейробиологов из Гарвардской медшколы выяснила, почему при коронавирусе на какое-то время пропадает обоняние.

Ранее кратковременная утрата обоняния (аносмия) была признана основным и самым ранним неврологическим симптомом при коронавирусной инфекции. Эксперты полагали, что вирус поражает клетки в верхней части полости носа, поэтому нейроны не передают сигналы о запахах в мозг.

Новое исследование, опубликованное в журнале Science Advances 24 июля, опровергло выше упомянутое предположение.

«Изменения в обонянии пациентов, вызываемые новым коронавирусом, связаны не с прямым инфицированием нейронов, а с воздействием на работу поддерживающих клеток», – сказал один из авторов исследования Сандип Роберт Датта.

Он пояснил, что открытие дало надежду на то, что в большей части случаев коронавирус не приводит к серьезному повреждению нервных сетей. То есть после выздоровления нейроны не будут меняться, а полная потеря обоняния человеку не грозит.

    You really make it seem so easy with your presentation but I find this matter to be really something which I think I would never understand.
    It seems too complex and very broad for me.
    I am looking forward for your next post, I will try to get the hang of it!

  8. First of all I would like to say excellent blog! I had a quick question that I’d
    like to ask if you do not mind. I was interested to find
    out how you center yourself and clear your thoughts prior to writing.
    I have had a tough time clearing my mind in getting my thoughts out there.
    I truly do enjoy writing however it just seems like the first 10 to 15 minutes are generally wasted simply just trying to figure out how to begin. Any recommendations or hints?

    My husband and i have been comfortable Peter managed to carry out his
    investigations using the ideas he obtained from your own web site.

    It’s not at all simplistic to just always be freely giving
    secrets and techniques which usually others might have been making money
    from. We take into account we need the writer to thank for this.
    The main illustrations you’ve made, the straightforward web site menu, the friendships your site make it possible to promote – it’s got
    all awesome, and it’s really helping our son and us do think that topic is brilliant,
    and that is rather mandatory. Many thanks for
    the whole thing!
