Numerous food allergies have been identified, but some are more widespread than others. DBV-Technologies, based in France, has been looking at ways of treating a few of the most common varieties, namely egg, cows’ milk protein and peanut.
At DBV Technologies.com you can find a full description of the company, its products, the techniques and thinking that lie behind its solutions and news of the latest developments concerning the firm’s progress in this important field. There are separate sections for each of the main ‘Viaskin’ patches that are being worked upon, such as the Viaskin milk patch, (http://www.dbv-technologies.com/en/viaskin-products/viaskin-milk), which is designed to help those with a milk allergy, especially very young children. The patch’s design and basic mechanism of action is the same for all its variants – an adhesive patch, coated with a layer of allergens, which forms a condensation chamber in contact with the skin to enable the allergens to penetrate the epidermis and reach the tolerogenic Langerhans cells, starting a process of desensitization. Although the concept is simple, the manufacture of these patches is a hi-tech operation carried out at DBV-Technologies’ labs (pictured below).
