There is no interferon tau. There was a letter to the editor earlier
this year, probably in Nature, dealing with the problem. Apparently some
people use a tau on their word processors to stand for a gamma, since
there is no ASCII code for a lower-case gamma. They intend to remove the
tau before submitting the paper and draw in a gamma by hand. However,
sometimes they forget, and several papers have appeared about interferon
tau.
