Autoimmune Diseases
An Introduction to Autoimmune diseases
Autoimmunity and deregulation of the immune system contribute to many skin diseases, including systemic sclerosis, dermatomyositis, psoriasis, vitiligo, alopecia areata and lichen sclerosus; inflammatory diseases such as hidradenitis suppurativa, allergic contact dermatitis and atopic eczema; and autoimmune blistering diseases, including pemphigus vulgaris, bullous pemphigoid, epidermolysis bullosa acquisita and dermatitis herpetiformis. Established treatments for autoimmune diseases include systemic corticosteroids and immunosuppressive therapies, while new therapies in development include biologic therapies targeting cytokines such as tumour necrosis factor alpha and interleukins (ILs) IL-23 and IL-17; enzymes such as Janus kinase-1 (JAK-1); and the regulatory protein-retinoic acid receptor-related-orphan-receptor-gamma t (RORγt).
