A Possible Use of Cholinergic Drugs in Pemphigus Vulgaris
Human epidermis shows a non-neuronal cholinergic system including keratinocyte (kc) acetylcholine (Ach) axis which is composed by enzymes and two families of Ach receptors (muscarinic and nicotinic receptors). The activity of these two receptors can regulate the interkeratinocytes and kcs-extracellular…

Ultrastructure of acantholysis in pemphigus foliaceus reexamined from the current perspective
Background Pemphigus foliaceus (PF) is a chronic cutaneous autoimmune blistering disease that is characterized by superficial blistering of the skin, and according to the current perspective is caused by autoantibodies directed against desmoglein 1 (Dsg1). Objectives To examine early acantholysis…

Why Lesions Occur at Different Sites
By Grant J. Anhalt, M.D. Johns Hopkins Dermatology I will attempt to clarify what we know about the antibody response in various forms of pemphigus and how the distribution of the targeted antigens affects the location of lesions. The synthesis…
