Ok, gut cells show AB0-markers too. Can they be agglutinated? They are
in a lining. Of course they could be attacked in some way, probably
decreasing the permeability of the lining. If the IgA defense doesn't
work (gut lining is protected by IgA against lectins).
I think it's also important that gut cells are rather short-lived. They
life only for 4 days anyway. I think therefore the effects of an attack
should be lesser.
If gut cells die they can simply leave the body the natural way - out
the usual way. Inside the bloodstream it would probably be much worse.
Imune defense, particularly macrophages must take care of any alien stuff.

Then the question is in which extent. And which *kind* of lectin
molecules. For example I'd think that very long lectins will pass less
easy than smaller ones.
I think it would only be valid to test lectin effects *after* passing
the gut wall (as far as they pass).
If lectin effects were really serious then it should be possible to
measure it's effects in the blood. Simply after a meal.
Maybe the usual tiredness after a meal ("soup coma") has something to do
with it.
Maybe lectins increase the (general) permeability of the lining.
That would be a real severe topic.
