De ce virusul duce la pierderea mirosului?<\/p>\n
Cercet\u0103torii \u0219i medicii care diagnostic\u0103 \u0219i trateaz\u0103 cazurile de COVID-19 explic\u0103 faptul c\u0103 anosmia, pierderea capacit\u0103\u021bii de a sim\u021bi mirosuri, reprezint\u0103 unul dintre simptomele infect\u0103rii. La c\u00eeteva luni de la primele cazuri confirmate, oamenii explic\u0103 faptul c\u0103 au descoperit o posibil\u0103 cauz\u0103 a acestui fenomen. Infec\u021biile virale, precum r\u0103celile sau cele care afecteaz\u0103 sinusurile sau tractul respirator superior, pot duce la pierderea sim\u021bului mirosului. \u00cen majoritatea cazurilor odat\u0103 cu dispari\u021bia simptomelor, printre care se num\u0103r\u0103 \u0219i nasul \u00eenfundat, situa\u021bia ar trebui s\u0103 revin\u0103 la normal. \u00cen unele cazuri, totu\u0219i, situa\u021bia tinde s\u0103 devin\u0103 cronic\u0103, anosmia dur\u00eend luni sau chiar ani.<\/p>\n
Cei diagnostica\u021bi cu COVID-10 explic\u0103 faptul c\u0103 pierderea mirosului a survenit brusc, iar revenirea acestui sim\u021b a avut loc la fel de brusc, dup\u0103 o s\u0103pt\u0103m\u00een\u0103 sau dou\u0103. \u00cen cazul acestei infec\u021bii, pacien\u021bii acuz\u0103 pierderea sim\u021bului mirosului chiar \u0219i \u00een cazul \u00een cazul \u00een care c\u0103ile respiratorii nu erau blocate. Folosind scan\u0103rile computerizate, oamenii de \u0219tiin\u021b\u0103 au ajuns la concluzia c\u0103 \u00een cazul persoanelor care sufer\u0103 de COVID-19 partea \u00een care se afl\u0103 receptorii care analizeaz\u0103 mirosurile erau acoperi\u021bi de mucus \u0219i de \u021besut inflamat. Astfel, cercet\u0103torii au putut explica pierderea mirosului \u00een cazurile \u00een care mucusul nu blocheaz\u0103 c\u0103ile respiratorii.<\/p>\n
Studiile au demonstrat faptul c\u0103 SARS-CoV-2 infecteaz\u0103 organismul uman ata\u0219\u00eendu-se de receptorii ACE2, afla\u021bi pe suprafa\u021ba celulelor aflate \u00een tractul respirator superior. Inserarea virusului \u00een celulele umane fiind posibil\u0103 cu ajutorul unei proteine numite TMPRSS2. Aflat \u00een celulele umane coronavirusul se poate r\u0103sp\u00eendi, ceea ce duce la declan\u0219area unui r\u0103spuns inflamator, unii cercet\u0103tori consider\u0103 aceast\u0103 important\u0103 \u00een evolu\u021bia virusului \u0219i a degener\u0103rii st\u0103rii de s\u0103n\u0103tate a persoanei infectate.<\/p>\n
Ini\u021bial, cercet\u0103torii suspectau faptul c\u0103 SARS-CoV-2 este responsabil \u0219i de distrugerea neuronilor olfactivi, responsabili de transmiterea semnalului oferit de interac\u021biunea dintre receptori \u0219i diferite molecule.<\/p>\n","protected":false},"excerpt":{"rendered":"
