The skin, the largest organ of the body, is a highly complex and organised tissue comprised of a vascularised dermal layer and an avascular epidermis consisting of multiple layers of differentiated keratinocytes. As well as providing a physical barrier to environmental challenges, the epidermis is the first line of defence against invading pathogens. Central to maintenance of a healthy epidermis is a tight and highly ordered cell to cell adhesion network including adherens, desmosomes and gap junction intercellular communication channels – the epidermal junctional nexus. Connexins (Cx), gap junction proteins, are expressed throughout the epidermal layers in a complex and overlapping pattern suggesting an important role in skin homeostasis.
