Approximately every 5 yr, Clinical Reviews in Allergy and Immunology deviates from its usual practice of publishing volumes devoted to one theme to including papers that cover a range of subjects. This issue is one such exception and arose following a symposium at the International Institute for Research in Autoimmune Diseases named AESKU.KIPP Institute at their Wendelsheim facility. The AESKU.KIPP Institute was a particularly venue because it was initially established by a German diagnostic company and a Swiss benefactor, Karl- Heinz Kipp. The goal of the Institute was to develop a unique atmosphere to encourage original research in the field of autoimmunity and clinical immunology. The thought was to create an institute where young scientists from throughout the world could come for short periods of time to learn newer methodologies in both clinical immunology and also molecular biology. This theme contains several of the papers presented at the opening of the Institute and are incorporated herein because they focus on several unique aspects of clinical immunology, often referred to as the mosaic of autoimmunity.
