COVID-19 is a human respiratory syndrome caused by SARS-CoV-2 virus infection that has a high rate of infection and mortality. Viruses modulate the host's machinery by altering cellular mechanisms that favor its replication. One of the mechanisms exploited by viruses is protein glycosylation that occurs in the endoplasmic reticulum (ER) and Golgi complex. When ER function is impaired, there is an accumulation of unfolded proteins leading to ER stress. To maintain homeostasis, the cells trigger an adaptive signaling mechanism called Unfolded Proetin Response (UPR), which helps cells deal with stress, but in severe conditions, this process activates apoptosis. UPR forms a barrier to intracellular pathogens, such as viruses, preventing their survival. Therefore, it is necessary to study the cellular functioning of the processes of protein glycosylation and UPR in order to develop a therapy for the treatment of COVID-19. (AU)
