A Possible Use of Cholinergic Drugs in Pemphigus Vulgaris

02 Jan 2013 (Around the Globe & News and Information)

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 matrix adhesion modifying the regulation of intercellular adhesion molecules like cadherins and integrins. Some authors demonstrate that acantholysis in pemphigus…
