项目摘要

Abstract Understanding the mechanisms and identifying regulators of immune cell development and differentiation are critical for developing new and more effective therapeutics. The fast advancement of genomic technologies provides an unprecedented opportunity to study the immune cells at the system level. The noise in the high throughput measurements and the complexity of multiple omics data make it an urgent need for developing novel and powerful systems biology approach for integrative analysis to reveal the underlying regulatory mechanisms for immune system. We propose a new method to integrate multiomics data at the genetic network level for identification of key regulators deciding the cell state and cell fate (Specific Aim 1). We will apply the method to systematically uncover the regulatory mechanisms in the mouse immune system by analyzing 86 immune cell populations (Specific Aim 2). We will also perform comparative analysis of the human and mouse immune cells to reveal the conserved regulatory code for immune cell specification (Specific Aim 3). We will rigorously assess the performance of the computational analysis, experimentally confirm the importance of the identified key regulators and investigate their roles in regulating immune cell functions. Once complete, the proposed work will provide not only a general tool for integrative analysis of multiomics data but also specific mechanistic insights for understanding the regulation of immune system functions.

抽象的了解免疫细胞发育的机制和确定调节剂差异化对于开发新的，更有效的治疗学至关重要。快速基因组技术的进步为研究该研究提供了前所未有的机会免疫细胞在系统水平上。高吞吐量测量和多种OMIC数据的复杂性使得迫切需要开发新颖而有力的功能集成分析的系统生物学方法，以揭示潜在的调节免疫系统的机制。我们提出了一种新方法，以整合多词数据的数据用于识别关键调节器的遗传网络水平决定细胞状态和细胞命运（特定目标1）。我们将应用该方法系统地发现调节机制在小鼠免疫系统中，通过分析86个免疫细胞群体（特定目标2）。我们将还对人和小鼠免疫细胞进行比较分析以揭示免疫细胞规范的保守监管代码（特定目标3）。我们会严格评估计算分析的性能，在实验上证实确定的关键调节剂并研究了它们在调节免疫细胞功能中的作用。一次完整的工作不仅将为整合分析提供一般工具多媒体数据，也是特定的机械见解，以理解调节的调节免疫系统功能。
