Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)is the causative agent of the coronavirus disease 2019(COVID-19), which spreads rapidly in humans and endangers global health and economy. There are no specific and effective antiviral drugs for the treatment of COVID-19 currently. To infect host cells successfully for a virus, receptor binding and virus internalization are considered to be the initial steps. A key to combat SARS-CoV-2 infection is to investigate the viral receptors, which determine its infectivity and host range. The discovery and identification of cell receptors for SARS-CoV-2 will provide new therapeutic targets for COVID-19. This article reviews the recent findings on the entry and attachment receptors for SARS-CoV-2.
