Figure 6.
Rationale of pemphigus therapies. The five targeted areas where immuno-intervention may play a role in controlling disease activity in PV, PF and FS are shown in this figure. A PV patient is depicted with the targeted sites: (1) elimination of the autoantigen or triggering environmental antigen, (2) deletion of autoreactive and regulatory T cell activation, (3) deletion of autoreactive B cell responses, (4) elimination of circulating autoantibody and (5) altering the keratinocyte responses to pathogenic autoantibodies (epidermis becomes “resistant” to these autoantibodies).
