C. amycolatum induces RNase 7 expression in primary keratinocytes and in an organotypic skin equivalent. (a) Treatment of human primary keratinocytes for 22–24 h with living C. amycolatum induced RNase7 gene expression as measured by real-time PCR. (b) ELISA analyses revealed also an increased secretion of RNase 7 by keratinocytes upon stimulation with living C. amycolatum. Shown are means ± s.e.m. of six stimulations (**p < 0.01, Student’s t test). (c,d) An organotypic skin equivalent was treated with living C. amycolatum for 22–24 h. (c) RNase7 gene expression was analyzed by real-time PCR and (d) RNase 7 secretion was determined by a RNase 7-specific ELISA of the culture medium. Shown are means ± s.e.m. of four different skin equivalents (*p < 0.05, Student’s t test).
