Manish Bhattacharjee tells us a story of how tick's saliva induces allergic reactions. Seems that alpha-gal, one of its components and absent in humans, is the culprit. But they are also present in red meat and does not elicit such a reaction. How is the tick's alpha-gal different from the mammalian sources? Can we understand these better to understand allergies better?
