Quantification of claudin-3 and -8 and ZO-1-mRNA-level. RNA was prepared at 6 h p.i. from infected and control monolayers. mRNA expression of claudin-3, claudin-8 and ZO-1 were determined by qRT-PCR and GAPDH was used for normalization. Data are means±s.e.m. of x-fold induction over controls (n=5, **P<0.01 compared with untreated control).
