ERVW-1 and infection: Compiled data from nine donors clearly demonstrated results that were similar to our prior publication (Mashiba et al., 2014); under conditions of matched infection in which there was no significant difference in HIV Gag pr55 levels between wild-type and vpr-null infections, all three forms of Env were significantly more abundant in the wild-type infection (gp160: 4-fold, p<0.002; gp120: 6-fold, p<0.002; gp41: 3-fold, p<0.001).
