RNase 7 contributes to the antimicrobial activity of human stratum corneum against C. amycolatum. (a) To test the neutralizing activity of the RNase 7 antibody C. amycolatum was incubated for 3 h at 37 °C with RNase 7 (1 µg/ml; R7) together with a specific RNase 7 neutralizing antibody (R7 + R7-Ab). RNase 7 alone (R7) or together with an irrelevant antibody (R7 + irr. Ab) served as positive controls. (b) C. amycolatum was incubated for 3 h with stratum corneum extract alone (s.c.), in the presence of an irrelevant control antibody (s.c. + irr. Ab) or a specific RNase 7 antibody (s.c. + R7-Ab). After incubation serial dilutions were plated on agar-plates and the colony forming units (CFU) were determined the following day. Shown are means ± s.e.m. of five independent experiments (n.s. = not significant; **p < 0.01; ***p < 0.001, one-way analysis of variance ANOVA using Tukey’s multiple comparison test).
