Animals live in constantly changing environments that are rich in microbial life. Immune systems orchestrate the complex, dynamic relationships between animals and microbes by both eliminating pathogenic microbes as well as promoting the growth of beneficial microbiota. However, our understanding of innate immune mechanisms in most animal phyla, including vertebrates, remains limited. The proposed research addresses this considerable knowledge gap by exploiting the experimental advantages of echinoderm larvae to investigate immune responses in a relatively unexplored animal lineage. Echinoderm larvae are morphologically simple, free-swimming multicellular organisms equipped with a sophisticated cellular and molecular immune system. By integrating recently available sequencing data from several echinoderm species with technology for measuring gene expression at single-cell resolution, the proposed research will significantly advance our understanding of animal immunity. This proposal describes a collaborative, systems-level approach to define the regulatory mechanisms that control immune responses across different echinoderm species. This innovative analysis will reveal evolutionarily conserved principles of immune response as well as species-specific adaptations.

动物生活在不断变化的、富含微生物的环境中。免疫系统通过消除病原微生物和促进有益微生物群的生长来协调动物和微生物之间复杂的动态关系。然而，我们对大多数动物门（包括脊椎动物）的先天免疫机制的了解仍然有限。拟议的研究通过利用棘皮动物幼虫的实验优势来研究相对未探索的动物谱系中的免疫反应，从而解决了这一巨大的知识空白。棘皮动物幼虫是形态简单、自由游动的多细胞生物，具有复杂的细胞和分子免疫系统。通过将最近获得的来自几种棘皮动物物种的测序数据与以单细胞分辨率测量基因表达的技术相结合，拟议的研究将显着增进我们对动物免疫的理解。该提案描述了一种协作的系统级方法来定义控制不同棘皮动物物种免疫反应的调节机制。这项创新分析将揭示免疫反应的进化保守原理以及物种特异性适应。
