Skin Barrier provides every aspect of stratum corneum structure, function, and development, as well as detailed sections on barrier-repair strategies and the role of barrier function in diseases such as atopic dermatitis, psoriasis, and ichthyosis.

Features:

• Analyzes the defensive mechanisms of the stratum corneum barrier including the psychosensory, antioxidant, antimicrobial, proinflammatory, hydration, and desquamatory functions
• Examines the composition, signaling functions, and metabolic regulation of corneocyte and lipid-enriched extracellular matrix
• Describes developmental changes leading to barrier function in utero, the decline of the barrier function in aging, and key features that distinguish the mammalian epidermal barrier from that of other homeotherms
• Assesses the interrelationships and coregulation of the various types of barriers
