Pemphigus vulgaris (PV) is a disease of epidermal adhesion. Its pathogenesis is currently traced back to the action of autoantibodies against antigens located within the intercellular substance of keratinocytes, such as desmogleins and acetylcholine receptors. In the present paper, we sought to elucidate the non-IgG-mediated effects of PV sera on keratinocytes. Results showed that PV sera depleted of IgG were able to induce well-defined changes on keratinocyte morphology and metabolic activity.
If pemphigus vulgaris IgG are the cause of acantholysis, new IgG-independent mechanisms are the concause.

Abstract
Pemphigus vulgaris (PV) is a disease of epidermal adhesion. Its pathogenesis is currently traced back to the action of autoantibodies against antigens located within the intercellular substance of keratinocytes, such as desmogleins and acetylcholine receptors. In the present paper, we sought to elucidate the non-IgG-mediated effects of PV sera on keratinocytes. Results showed that PV sera depleted of IgG were able to induce well-defined changes on keratinocyte morphology and metabolic activity.File in questo prodotto:
