CAV1 and infection: In addition, siRNA-mediated knockdown of caveolin-1 was shown to have no effect on RSV morphogenesis and infection in cultured cells (Kipper et al., 2015), and there is some evidence that caveolin-1 might have an anti-viral role during virus infection (Gabor et al., 2013; Bohm et al., 2014; He et al., 2016).
