Objectives To construct a lentivirus vector containing the innate immune receptor LILRB5 and to obtain monocytes stably transfected with LILRB5. Methods LILRB5 was subcloned into the expression vector pEGFP-flag,which was then transiently transfected into 293 Tcells.The expression of LILRB5-GFP and LILRB5-flag was detected in293 Tcells transiently transfected with pEGFP-LILRB5-flag using immunofluorescence and flow cytometry(FCM).The lentivirus vector pHR-LILRB5 was constructed and co-transfected into 293 T...
