DBV-Technologies – providing potential solutions for milk and egg allergy sufferers.

Substantial numbers of people experience allergic reactions after ingesting either milk or hens’ eggs. DBV-Technologies (http://www.dbv-technologies.com/en/), a French research firm, is trying to find ways of diagnosing and treating these particular allergies. Substantial work has already gone into a peanut allergy treatment, and more recently, the viaskin egg allergy patch.

The Viaskin milk patch employs the same electrospray equipment as the other patches

This is manufactured in exactly the same way as its peanut and cows’ milk counterparts. An electrically-charged spray of antigens (emitted by the electrospray, as seen in the image below), covers the backing of the patch, which is made from titanium. The antigens dry out onto the patch and are retained there by means of electrostatic attraction. After application, the body’s natural warmth solubilizes these antigens, whereupon they are able to penetrate the upper layers of the skin. It’s here that the Langerhans cells are to be found. These cells are extremely tolerogenic, which makes them perfect for the purposes of tolerizing the body to allergens. And as an added bonus, all this takes place without having to fiddle around with oral drops or painful and potentially dangerous injections!
