1. A composition comprising:
a population of animal cancer cells that express a T cell co-stimulatory B-7 molecule selected from the group consisting of B7-1 and B7-2 on the surface of said cells at a level at least 10-fold above a wild-type population of said cells, said cells having been treated with a type II interferon (IFN) such that said cells have enhanced antigen presenting function relative to animal cancer cells that have not been treated with a type II interferon (IFN); and
a type I IFN in isolated form.
