Zusammenfassung
In der Gruppe von angeborenen Störungen der Immunregulation werden verschiedenartige Erkrankungen zusammengefasst, die alle im klinischen Bild vorrangig durch Autoimmunerkrankungen an verschiedenen Organen und/oder eine Lymphoproliferation auffallen. Bei der Erforschung dieser Erkrankungen wird deutlich, dass sehr unterschiedliche Pathomechanismen zur Immundysregulation bzw. Autoimmunität führen können: So führen eine defekte Apoptose der Lymphozyten bei ALPS und eine gestörte Zytotoxizität der NK-Zellen und zytotoxischen T-Zellen bei HLH-Syndromen zu einer Lymphoproliferation, Hepatosplenomegalie und zu Zytopenien. Daneben zeigen Störungen in der Toleranzentwicklung des Immunsystems Autoimmunerkrankungen mit v. a. autoimmunen Endokrinopathien. Der Defekt der zentralen Toleranzentwicklung im Thymus beim APECED-Syndrom führt neben diesen multiplen Endokrinopathien zu einer chronischen mukokutanen Candidiasis, während sich der Defekt in der peripheren Toleranzentwicklung beim IPEX-Syndrom zusätzlich durch eine schwere, chronisch-entzündliche Darmerkrankung mit früher Manifestation zeigt. Die Entdeckung der ursächlichen Gene dieser Erkrankungen und die Studien an entsprechenden Mausmodellen leisten einen wichtigen Beitrag, um die komplexen Mechanismen zur Entstehung der Immundysregulation zu verstehen und möglicherweise neue Therapiestrategien für die Patienten zu entwickeln.
Abstract
The term diseases of immune dysregulation is an umbrella term for various diseases which stand out due to autoimmunity and/or lymphoproliferation of secondary lymphoid organs. The investigation of these diseases linked to single-gene defects provides an insight into different pathomechanisms of immune dysregulation or rather autoimmune phenomena. A defect of lymphocyte apoptosis in ALPS syndromes and an impairment of cellular cytotoxicity in hemophagocytic lymphohistiocytosis syndromes lead to lymphoproliferation, hepatosplenomegaly and autoimmune cytopenia. In addition a dysfunction in the development of immune tolerance causes autoimmune disease often with the involvement of endocrine organs. The APECED syndrome is caused by a disruption of central tolerance and shows in addition to autoimmune polyendocrinopathy a chronic mucocutaneous candidiasis. The defect in the development of peripheral tolerance in IPEX syndrome leads to a severe enteropathy in early childhood. The discovery of the responsible gene defects of these diseases and studies using the corresponding mouse models make an important contribution to the understanding of immune dysregulation and can possibly help in the development of new therapeutic strategies for these patients.
