I guess my question boils down to the effects of g-IF on epithelial cell
lines in vitro. From my course, I know that g-IF can induce MHC Class II
expression on epithelial cells. What I'm wondering is whether or not it
can also induce B7 expression in these cells.
If B7 is coexpressed with Class II molecules, then a stronger case could
be made for neo-class II expression as a factor in the development of
autoimmunity than of peripheral tolerance.
