BALB/c thio-PEM were left untreated selleck screening library (N) or were treated for 24 h with IL-4 or TGF-β, after which cell lysates were prepared for Western blot. Cell lysates were also prepared from total mouse brain, liver, kidney and spleen tissue. Table  S1 Basal gene expression levels (DCT ± SEM) in unstimulated naive macrophages. “
“Aicardi–Goutières

syndrome (AGS) is a genetically determined disorder, affecting most particularly the brain and the skin, characterized by the inappropriate induction of a type I interferon-mediated immune response. In most, but not all, cases the condition is severe, with a high associated morbidity and mortality. A number of important recent advances have helped to elucidate the biology of the AGS-related proteins, thus providing considerable insight into disease pathology. In this study, we outline the clinical phenotype of AGS, paying particular attention to factors relevant to therapeutic intervention. We then discuss the pathogenesis of AGS from a molecular

and cell biology perspective. Finally, we suggest possible treatment strategies in light of these emerging Selleck LY2606368 insights. Other Articles published in this series Mouse models for Aicardi–Goutières syndrome provide clues to the molecular pathogenesis of systemic autoimmunity.

Clinical and Experimental Immunology 2014, 175: 9–16. Aicardi–Goutières syndrome: a model disease for systemic autoimmunity Clinical and Experimental Immunology 2014, 175: 17–24. We have previously published a description of the genotype–phenotype correlation in 121 patients with Aicardi–Goutières syndrome (AGS) [1]. Based on that work, and an ongoing exercise to assimilate clinical and laboratory data from >250 cases (http://www.nimbl.eu/ni/Home), the natural history of AGS is becoming clearer. In a significant minority of patients with AGS, problems are recognized Cyclin-dependent kinase 3 at birth, i.e. the disease process begins in utero. Over time, severe neurological dysfunction manifests as progressive microcephaly, spasticity, psychomotor retardation and, in approximately 35% of cases, death in early childhood. Typical clinico-radiological features include intracranial calcification, white matter changes and raised numbers of white cells in the cerebrospinal fluid (CSF). To a remarkable degree this form of the disease, seen most consistently in association with mutations in TREX1, RNASEH2A and RNASEH2C, mimics the sequelae of congenital, transplacentally acquired infection (hence the tag: ‘pseudo-TORCH’ syndrome – Toxoplasmosis, Rubella, Cytomegalovirus and Herpes) [2]. More frequently, a later-onset presentation of AGS is seen, occurring in some cases after several months of normal development [3, 4].
