Background: Drebrin binds to F-actin and CXCR4 in T cells. Thus, it is a potential candidate for the modulation of HIV-1 infection. Results: Drebrin and CXCR4 accumulate at viral attachment areas. Drebrin knockdown decreases F-actin polymerization, and increases local profilin accumulation and HIV-1 infection. Conclusion: Drebrin inhibits HIV-1 entry by stabilizing HIV-1-triggered F-actin polymerization. Significance: Modulation of actin dynamics differentially regulates each viral step for an effective viral infection. © 2013 by The American Society for Biochemistry and Molecular Biology, Inc.
