Fig. 2. Correlation of IFN
-induced changes in the non-restrictive pore descriptor ß with increases in permeability of FD10. (A) Changes in the values of the restrictive (
) and non-restrictive (ß) pore descriptors calculated from the PEG oligomer permeability profile as described in the Materials and Methods following incubation of T84 monolayers with IFN
(0-100 ng/ml) for 48 hours. (B) Apparent permeability (Papp) of 10 kDa fluorescent dextran (FD10) measured under the same conditions. Data are expressed as mean±s.e.m. of n=4-6 monolayers in each group. Significant differences in Papp were observed; **P<0.01; *P<0.05 compared with control as indicated.
