Experts led by the University of Dundee have discovered the gene which causes dry skin, leading to eczema and asthma.
The gene produces the protein filaggrin, which helps the skin form a protective outer barrier.
Experts hope to use the discovery for more effective therapies to tackle the root causes of the conditions, rather than simply treating the symptoms.
Nice to see they are moving forward on this, although the cynic inside me says that it's only because of the huge number of little children who are affected, poor mites.
Certainly understanding the how and why should help with remedial treatments. I hope they come out with them soon.
