Keratinized structures

Keratinized structures, such as the stratum corneum, hair, and nails, are specialized tissues composed primarily of keratin proteins that provide a robust physical barrier for the body (Source: StatPearls, 2023). These structures are formed through the process of keratinization, where keratinocytes differentiate and eventually lose their nuclei to form a cornified layer that prevents desiccation and protects against environmental pathogens (Source: NIH, 2010). In clinical practice, these structures are the focus of treatments for conditions like hyperkeratosis, psoriasis, and fungal infections (Source: Wikipedia, 2024). Drugs such as keratolytics (e.g., salicylic acid) work by breaking down the intercellular cement between these structures, while others like terbinafine accumulate within them to exert antifungal effects (Source: PubChem, 2024). Consequently, while not a single molecular receptor, keratinized structures are essential pharmacological sites for dermatological health and disease management.
