B Cells in Autoimmune Diseases

Abstract: The role of B cells in autoimmune diseases involves different cellular functions, including the well-established secretion of autoantibodies, autoantigen presentation and ensuing reciprocal interactions with T cells, secretion of inflammatory cytokines, and the generation of ectopic germinal centers. Through these mechanisms B cells are involved both in autoimmune diseases that are traditionally viewed as antibody mediated and also in autoimmune diseases that are commonly classified as T cell mediated.

“…Infection-related immune dysregulation is a multifaceted mechanism, which emphasizes the close relationship between viruses and immune system [97]. The examples reported in this minireview suggest that viruses can profoundly subvert the immune system, leading also to the development of severe autoimmune diseases.…”

“…However, there are other ways B cells can contribute to autoimmunity including secretion of pro- or anti- inflammatory cytokines and presentation of self-antigens to autoreactive T cells (32). B cells express MHCII and costimulatory proteins and therefore may present antigen to CD4 T cells.…”

“…Несмотря на то что ИВРЗ существенно различаются по спектру и тяжести клинических проявлений и лабора-торных нарушений, они имеют общие патогенетические механизмы, в частности связанные с патологической акти-вацией аутореактивных В-клеток [1][2][3]. При всех заболева-ниях наблюдается развитие тяжелых, прогностически не-благоприятных вариантов течения, резистентных к стан-дартной глюкокортикоидной и иммуносупрессивной тера-пии, что диктует необходимость разработки новых патоге-нетически обоснованных методов лечения.…”

“…Действительно, у больных БШ и ССД, не-смотря на хороший клинический эффект, не происходило нормализации уровней специфических для этих болезней аутоантител. Отсутствие динамики аутоантител при ССД и БШ, по-видимому, можно объяснить неполным удалени-ем В-лимфоцитов из центральных лимфоидных органов и синтезом этих антител длительно живущими плазмати-ческими клетками памяти в костном мозге, которые не экспрессируют CD20 [3].…”
