Establishment of HIV-1 model cell line GHOST（3） with stable DRiP78 and NHERF1 knockdown

Chemokine receptors CXCR4 and CCR5 are indispensable co-receptors for HIV-1 entry into host cells. In our previous study, we identified that dopamine receptor-interacting protein 78（DRi P78） and Na＋-H＋ exchanger regulatory factor 1（NHERF1） are the CXCR4 and CCR5 homo- or hetero-dimerinteracting prot...

Summary:Chemokine receptors CXCR4 and CCR5 are indispensable co-receptors for HIV-1 entry into host cells. In our previous study, we identified that dopamine receptor-interacting protein 78（DRi P78） and Na＋-H＋ exchanger regulatory factor 1（NHERF1） are the CXCR4 and CCR5 homo- or hetero-dimerinteracting proteins. DRi P78 and NHERF1 are able to influence the co-receptor internalization and intracellular trafficking. Over-expression of NHERF1 affects the ligands or HIV-1 gp120-induced CCR5 internalization and HIV-1 production. It is reasonable to speculate that DRi P78 and NHERF1, as well as the signaling pathways involved in viral replication, would probably affect HIV-1 replication through regulating the co-receptors. In this present study, we designed two short hairpin RNAs（sh RNAs） targeting the DRi P78 and NHERF1, respectively, and constructed the p Lenti6/BLOCK-i T-DEST lentiviral plasmids expressing DRi P78 or NHERF1 sh RNA. The packaged lentiviruses were used to transduce the widely-applied HIV-1 model cell line
