Effect of actin binding compounds on NIH 3T3 cells. NIH 3T3 cells were pretreated with media alone or media containing either lat A (white bars), cyto B (black bars), or jas (dotted bars). Cells were infected with Py (at an MOI of 10) for 1 h in media alone or media containing the above compounds. The compounds were washed out, and neutralizing antibody was added at the indicated time points. Cells were examined for Py LTAg staining at 32 h. Approximately 500 nuclei were counted per sample, and the data are presented as described in the legend to Fig. 1.
