Epidermal keratinocyte plasma membrane

The epidermal keratinocyte plasma membrane is the fundamental lipid bilayer that encloses keratinocytes, the primary cells of the skin's epidermal layer. It serves as a critical interface for cell-cell communication and provides the structural foundation for the skin's barrier function through specialized junctions like desmosomes and adherens junctions [PMID: 25611318]. This membrane is not a single molecular target but rather a complex cellular structure containing numerous proteins, including receptors like the Epidermal Growth Factor Receptor (EGFR) and various cytokine receptors that are key therapeutic targets in inflammatory and neoplastic skin diseases [PMID: 30245213]. In conditions such as atopic dermatitis and psoriasis, the integrity and composition of the keratinocyte membrane and its associated lipid matrix are often compromised, leading to impaired barrier function and chronic inflammation [PMID: 29355414]. Consequently, while drugs may interact with specific components of the membrane, the membrane itself is viewed as a structural component of the integumentary system rather than a discrete pharmacological target. Therapeutic interventions often aim to restore the barrier properties of this membrane or modulate the signaling of the proteins embedded within it to treat dermatological disorders.

Drugs typically target specific receptors (e.g., EGFR), enzymes, or ion channels located on or within this membrane structure rather than the membrane itself.
