FIG 3.

SEVI differentially influences the numbers and depths of penetrating virions in human cervical tissues. (A and B) Bar graphs of the number of penetrating virions (A) and average virus penetration (B) with and without SEVI treatment for ectocervix and endocervix. (C) Histograms of the distributions of penetration depths for untreated (top) and SEVI-treated (bottom) HIV-1 in the ectocervix (left) and endocervix (right). The unshaded bars within each histogram show the percentages of nonpenetrators (NP), i.e., virions that penetrated to depths of <1 μm.
