项目摘要

PROJECT SUMMARY We are requesting an Administrative Supplement for the INCLUDE Project for R01 AR076242 “IRF5 and Macrophage Activation Syndrome in systemic Juvenile Idiopathic Arthritis”. The proposed studies for the in this Supplement are within the scope of the active parent grant, focused on Down syndrome (DS) and are aligned with the goals of the overall INCLUDE Project—Component 1: Targeted high risk – high reward basic science studies highly relevant to DS. Our studies take advantage of a growing registry and biorepository of DS individuals that has been established at the Benaroya Research Institute by Drs. Bernard Khor and Jane Buckner. The objectives of this administrative supplement are to better understand innate immune alterations in DS. Individuals with DS have immune dysfunction evidenced by decreased vaccine responses, increased severity of viral infections and increased incidence of certain autoimmune diseases, including autoimmune thyroiditis, type 1 diabetes and juvenile idiopathic arthritis (JIA). DS individuals also have increased type 1 IFN responses and increased amounts of some inflammatory cytokines and specific alterations in T and B cells. However, how these alterations lead to the overall changes in immunity in DS is not well-understood. Importantly, there has been much focus on adaptive immune responses in DS, with less focus on cells of the innate immune system, including monocytes and macrophages, important in the pathogenesis of many autoimmune diseases, including (JIA). This supplement is within the scope of the Parent R01 as it: 1) investigates monocytes and TLR responses in these cells, which are the focus of the parent R01, 2) relates to a form of juvenile arthritis seen more frequently in individuals with DS, as the parent grant focuses on another form of juvenile arthritis (systemic juvenile idiopathic arthritis (SJIA)), and 3) will leverage our existing single cell RNA-Seq (scRNA-Seq) data funded by the parent R01. Data generated from this supplement will inform our parent R01 by giving us additional monocyte scRNA-Seq datasets to compare with our already generated scRNA-Seq datasets from children with SJIA-associated MAS and matched controls. This supplement is within NIAMS INCLUDE Program priorities to better understand arthritic disorders in DS across the lifepan. Because monocytes and macrophages are key players in pathogenesis of all forms of arthritis, understanding whether these cells and their responses are dysregulated in DS will lead to a better understanding of their contributions to the increased incidence of arthritis in children with DS.

项目概要我们正在请求 R01 AR076242“IRF5 和系统性幼年特发性关节炎中的巨噬细胞激活综合征”。本项拟议的研究补助金在有效家长补助金的范围内，重点关注唐氏综合症 (DS)，并保持一致与总体 INCLUDE 项目的目标相一致 - 第 1 部分：有针对性的高风险 - 高回报基础科学与 DS 高度相关的研究。我们的研究利用了不断增长的 DS 注册和生物存储库博士在贝纳罗亚研究所建立的个人。伯纳德·霍尔和简巴克纳。本行政补充的目的是更好地了解先天免疫的改变 DS。患有 DS 的个体存在免疫功能障碍，表现为疫苗反应降低、病毒感染的严重性和某些自身免疫性疾病（包括自身免疫性疾病）发病率的增加甲状腺炎、1 型糖尿病和幼年特发性关节炎 (JIA)。 DS 个体的 1 型 IFN 也有所增加反应和某些炎症细胞因子数量的增加以及 T 和 B 细胞的特定改变。然而，这些改变如何导致 DS 免疫的整体变化尚不清楚。重要的是，人们更多地关注 DS 中的适应性免疫反应，而较少关注先天免疫细胞系统，包括单核细胞和巨噬细胞，在许多自身免疫性疾病的发病机制中很重要，包括（贾）。该补充品属于 Parent R01 的范围，因为它：1) 研究单核细胞和 TLR 这些细胞中的反应，这是母体 R01 的重点，2) 与所见的一种幼年关节炎有关在患有 DS 的个体中更常见，因为家长资助的重点是另一种形式的幼年关节炎（全身性关节炎）幼年特发性关节炎 (SJIA))，3) 将利用我们现有的单细胞 RNA-Seq (scRNA-Seq) 数据由母公司 R01 资助。此补充生成的数据将通过为我们提供额外的信息来通知我们的家长 R01 单核细胞 scRNA-Seq 数据集与我们已经生成的儿童 scRNA-Seq 数据集进行比较 SJIA 相关的 MAS 和匹配的对照。该补充属于 NIAMS INCLUDE 计划优先事项更好地了解 DS 整个生命周期的关节炎疾病。因为单核细胞和巨噬细胞是关键各种形式关节炎发病机制的参与者，了解这些细胞及其反应是否 DS 失调将有助于更好地了解其对关节炎发病率增加的贡献患有 DS 的儿童。
