What layer of skin does pemphigus affect?

Pemphigus affects the outer of the skin (epidermis) and causes lesions and blisters that are easily ruptured.

Sometimes pemphigoid may look like hives or eczema without blisters.

What molecules are affected in bullous pemphigoid?

How does pemphigoid affect the body?

Pemphigoid is caused by a malfunction of the immune system and results in skin rashes and blistering on the legs, arms, and abdomen. Pemphigoid can also cause blistering on the mucous membranes. Mucous membranes produce mucous that helps protect the inside of your body.

Which layer does pemphigus vulgaris affect?

Now, all of the layers of the epidermis are rich in desmoglein 1 and 3, while mucosal cells predominantly have desmoglein 3. So, in individuals with IgG antibodies that bind to both desmoglein 1 and 3, a person develops mucocutaneous pemphigus vulgaris because it affects both the skin and the mucosa.

How long can you live with pemphigus?

For most people, the disease can be controlled with treatment. Many can eventually stop their treatment for a while. Before medicines like prednisone and azathioprine were used to treat pemphigus, a person lived about 5 years after getting pemphigus vulgaris, the most common type.
