Here the T cells are imbalanced and a specific protein is found to regulate the imbalance but the interferon is countering the protein's effects. Now you can target that in many ways and run all sorts of clinical trials.

Not saying this is bad - in fact, quite the contrary: it seems like a necessary stage on the way to more-sophisticated mechanitistic understanding.
