Genes within the cells in our model of skin can be switched on or off to test their effects in causing eczema. Genes that cause eczema make the skin more ‘leaky’ and more prone to inflammation.

We test ‘leakiness’ using a dye that can penetrate skin when it’s leaky and by measuring how much water escapes out from the skin surface.

We test ‘inflammation’ by measuring amounts of RNA and proteins produced by the skin cells.

Working with other groups of researchers worldwide, we are involved with analysing DNA from tens of thousands of people from different populations.

By comparing the DNA code in people with eczema to those without the condition, we can identify differences which may lead to the skin disorder.

These clues in the DNA code point to which genes we should investigate further.

DNA analysis produces large amounts of data which cannot be understood without careful statistical analysis.

DNA codes for RNA which codes for proteins and these can also be measured, to produce even more data.

Making sense of all this information requires mathematical analysis by experts in the Brown lab, working with our collaborators in Edinburgh, Dundee, Bristol and internationally.

Our research is motivated by patients and families who share their experiences of the effects of eczema, including itchy, dry, sometimes infected skin.

These symptoms can lead to discomfort, poor sleep, lack of concentration, social isolation and frustration with treatments that are at best only partially or temporarily effective.
