项目摘要

PROJECT SUMMARY Psychosocial stress has been well-documented to correlate with systemic lupus erythematosus (SLE) flares and poor SLE outcomes. How this occurs has not been well studied. We recently identified that psychosocial stress induces circulating IL6 produced by Adrb3-expressing brown adipocytes. Brown adipocyte-derived IL6 mediates immunometabolic reprogramming through hepatic IL6 signaling to support “fight or flight” responses to acute stress. We have generated preliminary data that chronic psychosocial stress may enhance mortality in murine models of SLE through this novel Adrb3/IL6 pathway. Here, we propose to dissect the role of the Adrb3/IL6 pathway in the impact of psychosocial stress on SLE pathogenesis in murine models. In addition to gaining biological insight into how psychosocial stress leads to increased immune activation in lupus, our studies would provide compelling pre-clinical data for potential human translation.

项目摘要社会心理压力已有充分记录在与全身性红斑狼疮（SLE）耀斑相关的相关性和不良的结果。这种情况的发生方式不是很好的研究。我们最近确定了这个社会心理应力诱导通过表达ADRB3的棕色脂肪细胞产生的循环IL6。棕色脂肪细胞衍生的IL6 通过肝IL6信号传导介导免疫代谢重编程以支持“战斗或飞行”反应急性应激。我们已经产生了初步数据，即慢性社会心理压力可能会增强死亡率 SLE的鼠模型通过这种新型ADRB3/IL6途径。在这里，我们建议剖析在鼠模型中，心理社会应力对SLE发病机理的影响中的ADRB3/IL6途径。此外对社会心理压力如何导致狼疮的免疫激活增加，我们研究将为潜在的人类翻译提供令人信服的临床前数据。
