项目摘要

PROJECT SUMMARY IL-1 is a master neuroimmune regulator. IL-1 activity is important for both physiological functions of the brain and pathogenesis of all CNS diseases. The cellular sources of IL-1 are not well defined and genetic access to manipulating IL-1-expressing cells is lacking. We have created an IL-1-trap mouse to visualize IL-1 expressing cells. In addition, we can inhibit or activate IL- 1-expressing cells by chemogenetic methods. Using this new tool, we will: 1) demonstrate distinct sets of cells express IL-1 in homeostasis and in different neuroimmune activation conditions; 2) determine the role of homeostatic IL-1-expressing cells on the neurochemical and behavioral consequences following peripheral and central inflammatory challenge; and 3) determine the role of the induced IL-1-expressing cells on the neurochemical and behavioral consequences following peripheral and central inflammatory challenges.

项目摘要 IL-1是一种主要的神经免疫调节剂。IL-1活性对于两种生理功能都是重要的和所有中枢神经系统疾病的发病机制。IL-1 β的细胞来源不充分，缺乏操纵表达IL-1 β的细胞的明确的和遗传的途径。我们创造了用IL-1 β诱捕小鼠观察表达IL-1 β的细胞。此外，我们可以抑制或激活IL- 通过化学发生学方法检测表达1 β的细胞。使用这个新工具，我们将：1）演示不同类型的细胞表达IL-1 β，处于稳态和不同的神经免疫激活状态 2）确定稳态IL-1 β表达细胞在神经化学和免疫调节中的作用。外周和中枢炎症激发后的行为后果;和3）确定诱导的IL-1 β表达细胞对神经化学和行为的作用，外周和中枢炎症激发后的后果。
