Ask Custom Question

The two proposed models of T-cell recognition are the Duel-receptor and Altered Self theories. We now know that thanks to the experimentation done by J.W. Kappler, the Altered Self model is the correct of the two.

But suppose back before this was known, what sort of experiment could we maybe do in order to differentiate between these two possible models? Again this is assuming we know about MHC restriction, but neither the T cell receptor, MHC molecules, nor their genes have been isolated/purified/sequenced.
