| Research Abstract |
Human endogenous retroviruses, which are remnants of ancestral retroviruses integrated into the human genome, are generally defective in viral replication. During HIV-1 infection, activation of human endogenous retroviruses have been observed in some groups. We investigated whether human endogenous retroviruses could suppress the replication of human exogenous retroviruses as HIV-1. In this study, we found that human endogenous retroviruses reduces release efficiency of HIV-1 through the coassembly between HIV-1 Gag and human endogenous retrovirus Gag. Furthermore, human endogenous retroviruses are copackaged into HIV-1 particles, and the infectivity of HIV-1 is drastically reduced by changing the morphology of HIV-1 particles.
