From Dr Google:

"Lectin is believed to worsen autoimmune disease in people who have a lectin sensitivity. Lectin is so resistant to being digested that it can cross over into the circulation system where it can cause damage to cells.

The immune system responds to lectin by producing antibodies. A blood test for lectin antibodies may be the best way to find out if you have a lectin sensitivity. Talk to your health care professional if you are having any of the following symptoms."

So it's thought that animal proteins can lead to antibodies that cross the BBB. I guess the same could be true for veggies. I've talked about autohemotherapy, an old treatment for diseases like Lupus or MS.
