BEIJING, Oct. 12(Xinhuanet) -- People allergic1 to peanuts may find relief in a new research by American scientists, according to Huffington Post Monday.
Scientists from the Northwestern University Feinberg School of Medicine have found a way to turn off allergic responses by creating an immune system tolerant to peanuts.
They attached peanut proteins, the source of the allergy2, to white blood cells of mice. Then the mice's immune systems would recognise the proteins and become tolerant to them.
When people eat peanuts, allergic human bodies would recognize peanut proteins as invading pathogens and trigger immune responses like throat swelling3, even closing up, which can be lethal4. Ditto for mice's bodies.
But when peanut protein attached to the body's own cells, the immune systems would regard the peanut proteins as perfectly5 normal and not attack the cells, said Paul Bryce, an assistant professor involved in the study. Then the allergic responses disappeared.
