Abstract

Pemphigus vulgaris (PV) acantholysis represents a complex phenomenon wherein a number of factors cooperates. PV serum is known to modulate important cellular events, including kinase activity, transcriptional regulation, and proteinase expression. Indeed, transduction of signals to the cell triggered by PV serum may induce proteinase up-regulation potentially responsible for disruption of epidermal adhesion and, ultimately, blister formation. Here, we sought to investigate this hypothesis by using both in vivo and in vitro models of PV. Microarray analysis on mouse skin tissues suggested that the equilibrium between extracellular proteinases and their inhibitors moved towards enhanced proteo..
