Mammalian skin cell membranes and local zinc-sensitive processes

Mammalian skin cell membranes and local zinc-sensitive processes refers to the complex physiological environment where zinc ions (Zn2+) interact with cutaneous structures and biochemical pathways. Zinc is an essential trace element that serves as a structural component in proteins and a cofactor for numerous enzymes involved in DNA synthesis and cell division, such as matrix metalloproteinases (MMPs) which are vital for skin remodeling (Gupta et al., 2014). At the cellular level, zinc ions stabilize cell membranes by protecting against oxidative damage and modulating the activity of various ion channels and transporters (Bettger & O'Dell, 1981). In clinical practice, topical zinc preparations like zinc oxide and zinc pyrithione are used to treat inflammatory skin conditions and fungal infections by altering local zinc concentrations and inhibiting microbial growth (Reeder et al., 2011). This target represents a broad pharmacological site of action rather than a single discrete protein, encompassing various zinc-dependent signaling cascades and structural interactions within the epidermis and dermis. Because it describes a collection of processes and anatomical sites rather than a specific molecule, it is not classified as a standard therapeutic target.

Zinc ions modulate the activity of over 300 enzymes, including matrix metalloproteinases (MMPs) and alkaline phosphatase, while also stabilizing cell membranes by preventing lipid peroxidation and regulating transcription via metal-regulatory element-binding transcription factor 1 (MTF-1) (Gupta et al., 2014; Bettger & O'Dell, 1981).
