Fig. 7. Reversibility of IFN
induced alterations in paracellular permeability of PEG oligomers. Cells were treated with 10 ng/ml IFN
for 48 hours. After this time IFN
was removed from the medium and the cells were allowed to recover for 24 or 96 hours:
, no recovery;
, 24 hours;
, 96 hours. A control profile (i.e. not exposed to IFN
) is also shown
. Data are mean±s.e.m. of four monolayers in each group.
