Acantholysis relates to the loss of which type of connections?

Acantholysis specifically refers to the loss of intercellular connections between keratinocytes, which are the predominant cell type in the epidermis of the skin. This phenomenon occurs primarily in certain skin diseases, notably pemphigus vulgaris, where autoantibodies target desmosomes—structures that facilitate cell adhesion among keratinocytes. When these connections are disrupted, it leads to the separation of skin cells and results in the formation of blisters.

Understanding acantholysis is significant in pathology because it highlights the pathophysiological mechanisms behind blistering disorders and informs diagnostic and therapeutic approaches. This process is distinct from the other options that relate to various types of cellular connections in different tissues but are not relevant to the skin's structural integrity.
