I think I too remember someting of this sort.  I'm sure its a model 
though.  Transfection would necessarily have to be done on a personal 
basis.  Also, because the co-receptors for the B7 family are implicated 
in stimulation (CD28) or tolerance (CTLA$), it would be important to to 
somehow skew the results toward interaction with CD28.
