This research group is interested in rare, genetic diseases which affect the epidermis. We seek to understand the cause of these diseases1-5, study differences in skin function and develop new patient-specific therapeutics for these orphan diseases.
One main interest for research is topical drug development for autosomal recessive congenital ichthyosis (ARCI), a very rare condition which affects roughly 800 persons in the UK (prevalence is 1 to 100,000 persons in the UK and the EU). ARCI can be life-threatening at birth. It is life-long condition with currently only limited and not sufficient therapy options. For more information on the Biology of the Skin.

View into cell culture incubator in our laboratory with primary human keratinocytes, fibroblasts and melanocytes from healthy control donors and patients cultured at 37°C, 90% humidity and 5% CO2. Samples are cultured with permission from Edge Hill University ethical commission (URESC), and all samples have been collected only after written consent has been granted.
An immune-fluorescence-cyto-chemistry (ICC) straining of keratinocytes grown and fixed on small cover slips. Cells were stained against keratin 10 (red) and GM130 (green) and counterstained with Dapi (blue). Keratin 10 is only expressed in differentiated keratinocytes. GM130 shows the Golgi apparatus within a cell and Dapi localises the DNA (nuclei).
We are proud to have a brand-new and state of the art histology suite. Standard procedures including H&E or Fontana-Masson staining are performed in these standard jars.
ARCI Drug Project
To develop new therapies for ARCI we have, together with British and international co-operation partners developed strategies to develop and advance new drugs for our patients (topical protein replacement therapy)6-8. New drugs are tested on 3D skin models we generate in-house9 and reduce the use of animals in our research significantly. Learn more about our therapy research.
We are also interested in the role of melanocytes (pigmented cells in the skin – these are the cells which allow tanning). Melanocytes play a role in rare skin diseases and are responsible for melanoma development. We are currently studying patient and healthy melanocytes in various studies to further our knowledge in pigmentation disorder origins (for example Neurofibromatosis, trichothiodystrophy, or vitiligo). Learn more about how stem cell research, expression profiling and epigenetic understanding can aid us in pigmentation disease knowledge gain.
ARCI Epigenetics Project
Tremendous progress has been made in recent years in the epigenetic understanding of the epidermis, which is a highly complex, ever changing tissue, with keratinocytes moving from the basal layer to the outermost layer during a process called “terminal differentiation”. This differentiation requires a highly orchestrated gene expression profile with genes switched on and off in each layer of the epidermis and if a gene is absent from this protocol due to a mutation (e.g. in ARCI patients), the process might be severely inhibited or changed. But not only gene expression is tightly controlled but also DNA methylation but also histone modifications. We have recently published our first preliminary results on how true mutations affect epidermal epigenetic profiles between healthy and ARCI patients. Learn more about our epigenetic skin studies.
