Cover Caption:

Cover

Cover: PV-IgG caused dissociation of cultured HaCaT cells without evidence of altered nuclear morphology. Cultured HaCaT cells were incubated with IgG from a healthy volunteer and then stained with a monoclonal antibody to desmoglein 3 (Dsg 3) to label desmosomes and with DAPI to evaluate nuclear morphology.
