(A and B) Effects of rhSDF-1β or MIP-1β on infectivity of pseudotyped virus with NL4-3/SDF1-51 chimeric envelope. U87.CD4.CXCR4 cells were preincubated with various concentrations of rhSDF-1β or rhMIP-1β at 37°C for 30 min. Then pseudotyped viruses with the NL4-3/SDF1-51 chimeric envelope (NL4-3/SDF1-51) (A) or NL4-3 WT viruses (NL4-3/WT) (B) were added to the cells. (C and D) Effects of anti-human SDF-1 Ab on the infectivity of pseudotyped virus with NL4-3/SDF1-51 chimeric envelope and NL4-3/WT envelope. Pseudotyped viruses NL4-3/SDF1-51 (C) and NL4-3/WT (D) preincubated with anti-human SDF-1 Ab were added to U87.CD4.CXCR4 cells. R.L.U., relative luciferase units.
