Figure 9: Effect of downmodulation of CD4 and CIB proteins in CD4+ T-lymphocytes on the expression of proteins implicated in HIV-1 entry.
From: CIB1 and CIB2 are HIV-1 helper factors involved in viral entry

Activated CD4+ T-lymphocytes were transduced with the empty vector (pLKO.1) or vectors leading to the expression of the indicated shRNAs, and the surface expression of the following molecules was measured by flow cytometry: CD3, CD4, CXCR4, LFA-1 and α4β7. Intracellular talin expression was also evaluated in permeabilized cells. In each case, the mean fluorescence intensity (MFI) and a representative fluorescence histogram are shown. For MFI, the values represent the mean ± SEM of 4 independent experiments using two different shRNAs per targeted gene and are expressed relative to values obtained for non-transduced cells. *P < 0.05, **P < 0.01 versus sh-SCRAM (Kruskal-Wallis test).
