Several proteins, such as those located in the dermal-epidermal junction zone and forming the hemidesmosomes, or those forming epidermal desmosomes are crucial for the maintenance of skin integrity. Defective function may be genetically determined due to impaired or absent production of specific proteins (i.e., epidermolysis bullosa) or due to autoimmune disorders that lead to the production of autoreactive antibodies targeting desmosomal or hemidesmosomal skin antigens. The latter group of diseases are classically named autoimmune blistering diseases of the skin. These can be divided in the pemphigoid group, where antigens are components of the hemidesmosomes, and pemphigus group, where desmosomal proteins are targeted.

Genetic and autoimmune disorders that result in skin fragility have significantly contributed to understanding the role of various molecular components in the skin. These conditions, characterized by blisters, erosions, wounds, and impaired wound healing, are rare but must be considered in clinical differential diagnoses. Key cutaneous adhesion structures include the epidermal basement membrane, anchoring fibrils, cell-matrix adhesions (e.g., hemidesmosomes and focal adhesions), and cell-cell adhesions (e.g., desmosomes and corneodesmosomes). These multiprotein suprastructures not only provide structural support but also participate in signaling processes and physiological or pathological conditions such as skin aging and wound healing. Additionally, dermal connective tissue plays a structural role and serves as a reservoir for proteases, growth factors, and cytokines.
