  (C) Activity of human mAbs 10 and CIS43, specific for P. falciparum CSP, and VRC01, an isotype control human mAb specific for HIV-1, on the proportion of motile sporozoites (left panel) and blood vessel entry (right panel). Four-minute videos of mice inoculated with the indicated mAbs were taken 10 min after sporozoite inoculation and manually counted. Data are pooled from 7 biological replicates, naïve and VRC01 (n=2), naïve and mAb 10 (n=2), VRC01 and CIS43 (n=3). No comparisons were statistically significant (Mann-Whitney for percent motile and Fisher's exact test for blood vessel entry).
