Cholesterol is a major constituent of detergent-resistant membrane microdomains (DRMs). We localized transmissible gastroenteritis virus (TGEV) spike (S) protein in DRMs in the viral envelope. Though S protein was not solubilized by cold non-ionic detergents, this behavior was unchanged when cholesterol was depleted from viral membrane by methyl-β-cyclodextrin (MβCD) and the protein did not comigrate...
Cholesterol present in the plasma membrane of target cells has been shown to be important for the infection by SARS-CoV. We show that cholesterol depletion by treatment with methyl-β-cyclodextrin (mβCD) affects infection by SARS-CoV to the same extent as infection by vesicular stomatitis virus-based pseudotypes containing the surface glycoprotein S of SARS-CoV (VSV-ΔG-S). Therefore, the role of cholesterol...
In this study, we addressed the question whether cholesterol is important for transmissible gastroenteritis virus (TGEV), a porcine coronavirus, in the initiation of an infection. We found that cholesterol depletion from the cellular membrane by methyl-β-cyclodextrin (MβCD) significantly impaired the efficiency of TGEV infection. Infectivity was also reduced after depleting cholesterol from the viral...
