Impaired mitochondrial and metabolic function of fibroblasts derived from patients with recessive dystrophic and junctional epidermolysis bullosa
Abstrakt
Recessive dystrophic epidermolysis bullosa (RDEB) and junctional EB (JEB) are inherited disorders characterised by fragility and blistering of epithelial tissues leading to pain, pruritus, and adherent scarring. The severity and chronic nature of the resultant skin wounds significantly reduces quality and length of life.
Current therapies primarily consist of protective bandaging and nutritional supplementation; there is no cure for these disorders. Although the skin fragility results from a lack of C7 protein (RDEB) and laminin-332 (JEB), other serious aspects of these disorders, such as inflammation that interferes with healing and aggressive squamous cell carcinoma, have not been completely elucidated.
Recent research has suggested that mitochondrial function plays a significant role in skin healing.
