Review of host proviral and antiviral factors for SARS-CoV-2. Authors summarize current understanding of the interplay between SARS-CoV-2 and host cellular factors during virus entry and replication. They highlight ACE2 as the main receptor for viral entry, aided by cofactors like CD147, heparan sulfate, and neuropilin-1/2 to facilitate spike protein binding. Intracellular proteases like TMPRSS2 prime the spike protein to enable membrane fusion. Following entry and uncoating, cytosolic factors like SRPK1/2 kinases and VPS34 lipid kinase promote viral replication complex assembly and genome replication. Antiviral factors include defensin HD5 that blocks ACE2, cholesterol 25-hydroxylase that restricts membrane fusion, and ZAP/LARP1 that inhibit viral RNA production.

Host proviral and antiviral factors for SARS-CoV-2
Lu Lv, Leiliang Zhang
Virus Genes, doi:10.1007/s11262-021-01869-2
Throughout the viral life cycle, interplays between cellular host factors and virus determine the infectious capacity of the virus. The pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) poses a great threat to human life and health. Extensive studies identified a number of host proviral and antiviral factors for SARS-CoV-2. In this review, we summarize the current understanding of the interplay between SARS-CoV-2 and cellular factors during virus entry and replication. Our review will highlight the future direction of study on the infection and pathogenesis of SARS-CoV-2, as well as novel therapeutic strategies and effective antiviral targets for COVID-19.
