List of target antigens in pemphigus

This is an incomplete list that may never be able to satisfy particular standards for completeness. You can help by expanding it with reliably sourced entries.

Circulating auto-antibodies in the human body can target normal parts of the skin leading to disease. This is a list of antigens in the skin that may become targets of circulating auto-antibodies leading to the various types of pemphigus.
