re:Oral tolerance

It is possible though that inhaled antigens do all their tolerising in the gut. Many 
parasites that have a lung stage to their life cycle are coughed up and swallowed 
and thus end up in the gut (from which they are later spread). Could the same be 
true for peptide put up the nose of mice? 

Why then is the pulmonary route more efficient than the gut route...how about 
synergy between pulmonary tolerance and gut tolerance? How could you 
distinguish the two in an experimental system... how about tying off the oesophagus 
after admin of the peptide? How do you feed a mouse by drip though?
