IFI16 is an important player of the host intrinsic immune response. Among others, it has been reported to sense intermediate products of HIV-1 reverse transcription in the cytosol and to sequester the transcription factor Sp1 in the nucleus to attenuate viral gene expression. Here, we present three different methods to reduce IFI16 protein expression levels in HIV-1 primary target cells. These techniques can be adapted for the investigation of other cellular factors in primary macrophages an…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
