You may not have heard of epicutaneous immunotherapy before, but this technique is likely to become much better known soon through the research work performed by French firm DBV Technologies (http://www.dbv-technologies.com).
The 20th and 21st centuries have seen allergies take centre stage as a health issue. Frequently-occuring allergies range from everyday products like egg to the more exotic crabmeat.
DBV Technologies is now leading the way in combatting certain allergies through the Viaskin Patch (http://www.dbv-technologies.com/en/viaskin-technology/viaskin-patch).
The Viaskin platform is a patch which works upon application to the skin. The essential components of the patch include an electrostatically-charged backing and an adhesive crown.
The concept underlying this epicutaneous patch isn’t particularly complicated. A so-called ‘electrospray’ is used to spray minute quantities of an antigen onto the patch, facilitating optimal retention of its chemical properties.An ultra-moisturizing ‘condensation chamber’ formed between patch and skin allows these protein compounds to reach the tolerogenic Langerhans cells, where they begin the work of gradually desensitizing the body to these antigens.
If you’re a parent of a child with a milk allergy the Viaskin milk patch could be the answer to your prayers.
