Dendritic cells (DCs) bridge innate and adaptive immune responses by presenting antigens to T cells and releasing a variety of cytokines. Several subsets of DCs can be discriminated that engage specific transcriptional pathways for their development. Basic leucine zipper transcription factor ATF-like 3 (Batf3) is required for the development of classical CD8α\(^{+}\) and CD103\(^{+}\) DCs. By crossing mice deficient in Batf3 with atherosclerosis-prone low density lipoprotein receptor (Ldlr\(^{-/-}\))-deficient mice we here aimed to further address the contribution of Batf3-dependent CD8α\(^{+}\) and CD103\(^{+}\) antigen-presenting cells to atherosclerosis. We demonstrate that deficiency in Batf3 entailed mild effects on the immune response in the spleen but did not alter atherosclerotic lesion formation in the aorta or aortic root, nor affected plaque phenotype in low density lipoprotein receptor-deficient mice fed a high fat diet. We thus provide evidence that Batf3-dependent antigen-presenting cells do not have a prominent role in atherosclerosis.}, language = {en} } @article{GirschickWolfMorbachetal.2015, author = {Girschick, Hermann and Wolf, Christine and Morbach, Henner and Hertzberg, Christoph and Lee-Kirsch, Min Ae}, title = {Severe immune dysregulation with neurological impairment and minor bone changes in a child with spondyloenchondrodysplasia due to two novel mutations in the ACP5 gene}, series = {Pediatric Rheumatology}, volume = {13}, journal = {Pediatric Rheumatology}, number = {37}, doi = {10.1186/s12969-015-0035-7}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-149990}, year = {2015}, abstract = {Spondyloenchondrodysplasia (SPENCD) is a rare skeletal dysplasia, characterized by metaphyseal lesions, neurological impairment and immune dysregulation associated with lupus-like features. SPENCD is caused by biallelic mutations in the ACP5 gene encoding tartrate-resistant phosphatase. We report on a child, who presented with spasticity, multisystem inflammation, autoimmunity and immunodeficiency with minimal metaphyseal changes due to compound heterozygosity for two novel ACP5 mutations. These findings extend the phenotypic spectrum of SPENCD and indicate that ACP5 mutations can cause severe immune dysregulation and neurological impairment even in the absence of metaphyseal dysplasia.}, language = {en} } @article{PetersenKuntzerFischeretal.2015, author = {Petersen, Jens A. and Kuntzer, Thierry and Fischer, Dirk and von der Hagen, Maja and Veronika, Angela and Lobrinus, Johannes A. and Kress, Wolfram and Rushing, Elisabeth J. and Sinnreich, Michael and Jung, Hans H.}, title = {Dysferlinopathy in Switzerland: clinical phenotypes and potential founder effects}, series = {BMC Neurology}, volume = {15}, journal = {BMC Neurology}, number = {182}, doi = {10.1186/s12883-015-0449-3}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-139920}, year = {2015}, abstract = {Background: Dysferlin is reduced in patients with limb girdle muscular dystrophy type 2B, Miyoshi myopathy, distal anterior compartment myopathy, and in certain Ethnic clusters. Methods: We evaluated clinical and genetic patient data from three different Swiss Neuromuscular Centers. Results: Thirteen patients from 6 non-related families were included. Age of onset was 18.8 +/- 4.3 years. In all patients, diallelic disease-causing mutations were identified in the DYSF gene. Nine patients from 3 non-related families from Central Switzerland carried the identical homozygous mutation, c.3031 + 2T>C. A possible founder effect was confirmed by haplotype analysis. Three patients from two different families carried the heterozygous mutation, c.1064_1065delAA. Two novel mutations were identified (c.2869C>T (p.Gln957Stop), c.5928G>A (p.Trp1976Stop)). Conclusions: Our study confirms the phenotypic heterogeneity associated with DYSF mutations. Two mutations (c.3031 + 2T>C, c.1064_1065delAA) appear common in Switzerland. Haplotype analysis performed on one case (c.3031 + 2T>C) suggested a possible founder effect.}, language = {en} } @article{HedrichHofmannPabliketal.2013, author = {Hedrich, Christian M. and Hofmann, Sigrun R. and Pablik, Jessica and Morbach, Henner and Girschick, Hermann J.}, title = {Autoinflammatory bone disorders with special focus on chronic recurrent multifocal osteomyelitis (CRMO)}, series = {Pediatric Rheumatology}, volume = {11}, journal = {Pediatric Rheumatology}, number = {47}, issn = {1546-0096}, doi = {10.1186/1546-0096-11-47}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-125694}, year = {2013}, abstract = {Sterile bone inflammation is the hallmark of autoinflammatory bone disorders, including chronic nonbacterial osteomyelitis (CNO) with its most severe form chronic recurrent multifocal osteomyelitis (CRMO). Autoinflammatory osteopathies are the result of a dysregulated innate immune system, resulting in immune cell infiltration of the bone and subsequent osteoclast differentiation and activation. Interestingly, autoinflammatory bone disorders are associated with inflammation of the skin and/or the intestine. In several monogenic autoinflammatory bone disorders mutations in disease-causing genes have been reported. However, regardless of recent developments, the molecular pathogenesis of CNO/CRMO remains unclear. Here, we discuss the clinical presentation and molecular pathophysiology of human autoinflammatory osteopathies and animal models with special focus on CNO/CRMO. Treatment options in monogenic autoinflammatory bone disorders and CRMO will be illustrated.}, language = {en} }
