The Coronaviridae family includes the seven known human coronaviruses that cause mild to moderate respiratory infections (HCoV-229E, HCoV-NL63, HCoV-OC43, HCoV-HKU1) as well as severe illness and death (MERS-CoV, SARS-CoV, SARS-CoV-2). Severe infections induce hyperinflammatory responses that are often intensified by host adaptive immune pathways to profoundly advance disease severity. Proinflammatory responses are triggered by coronavirus entry mediated by host cell-surface receptors. Interestingly, five of the seven strains utilize three cell-surface metallopeptidases (CD13, CD26, and ACE2) as receptors, while the others employ O-acetylated-sialic acid (a key feature of metallopeptidases) for entry. Why coronaviruses evolved to use peptidases as their receptors is unknown, but the peptidase activities of the receptors are dispensable suggesting the virus utilizes/benefits from other functions of these molecules. Indeed, these receptors participate in the immune modulatory pathways that contribute to the pathological hyperinflammatory response. This review will focus on the role of coronavirus receptors in modulating immune responses.
