The impact of intrinsic ageing on the protein composition of the dermal-epidermal junction
نویسندگان
چکیده
The dermal-epidermal junction of human skin exhibits age-related remodelling, resulting in a flattened appearance and reduced surface area. Despite this, a paucity of information is available regarding which protein components change with advancing age. Here we report a significant reduction in the protein distribution of collagen IV (P<0.0001), collagen VII (P<0.001), collagen XVII (P<0.01), integrin β4 (P<0.001) and laminin-332 (P<0.0001) in intrinsically aged skin. The functional implication of this altered protein composition appears to be loss of structural integrity and may, in part, explain the increased fragility of aged skin.

متن کاملLetter to the editor concerning the article 'Geographical ancestry is a key determinant of epidermal morphology and dermal composition'.
BACKGROUND Geographical ancestry plays a key role in determining the susceptibility of human skin to external insults and dermatological disease. Despite this, studies of skin from individuals of diverse geographical ancestry focus primarily on epidermal pigmentation. Few reports characterize the gross morphology and composition of the dermis and dermal-epidermal junction (DEJ). OBJECTIVES To...
