Despite the fact that numerous COVID-19 studies have been published in the last 2 years, the interplay between the other early- and late-onset Alzheimer’s disease genes and COVID-19 have not been addressed. WebThere are three types of genes: immediate-early, early and late. The immediate-early genes are transcribed immediately after infection and ensure the transcription of early genes, which encode the proteins necessary for the viral replication. The late genes mostly encode structural proteins. Standing apart are genes expressed during latency.
