The chemokine-like mediator macrophage migration inhibitory factor (MIF) is a prominent human disease marker and a pivotal mediator of inflammatory, infectious and immune diseases including septic shock, colitis, malaria, rheumatoid arthritis, and atherosclerosis, as well as tumorigenesis. Translational applications emerging from MIF research have been delayed because of an incomplete mechanistic understanding of MIF´s pathobiology. Strikingly, MIF is an evolutionarily conserved protein that is found across kingdoms. Despite of its limited molecular size and lack of appreciable modular domains, MIF has been found to exhibit several sequential and three-dimensional structural motifs including two catalytic sites that provide this protein with a surprising functional complexity. In recent years, the applicants have significantly contributed to the elucidation of MIF structure and its role in human and plant disease and have performed comprehensive in silico characterization of plant MIFs. In the context of these findings, it is the aim of this joint ANR-DFG proposal to study the molecular links between MIF of human, plant and parasite (aphid) origin to identify potentially conserved functions in the regulation of immune responses between kingdoms. The applicants combine expert knowledge in immune regulatory mechanisms of human MIF and insect pathobiology as well as long-standing expertise in comparative plant immunity and molecular genetics of Arabidopsis thaliana and barley to study MIF functional and structural features in this cross-species/kingdom approach. They thus represent a unique interdisciplinary team combining in-depth expertise on MIF biochemistry, biology, and pathobiology, with plant genetics and biotechnology and infectious disease research. The collaborative project will enable us to shed first light on the role of plant and insect MIFs and on the functional relevance of the shared versus distinct motifs between the different kingdoms. We will systematically utilize the cross-kingdom analysis of MIF´s structure-function profile to better understand the mechanisms of MIF in infectious disease and plant immunity. In addition, the proposal will spark novel research into immune evasion mechanisms and evolutionary history of the MIF family.

趋化因子样介质巨噬细胞迁移抑制因子（MIF）是一种重要的人类疾病标志物，也是炎症、感染性和免疫疾病（包括脓毒性休克、结肠炎、疟疾、类风湿性关节炎和动脉粥样硬化）以及肿瘤发生的关键介质。由于对 MIF 病理学的机制了解不完整，MIF 的研究被推迟了。令人惊讶的是，MIF 是一种进化上保守的蛋白质。尽管其分子大小有限且缺乏明显的模块结构域，但近年来，申请人发现 MIF 表现出几个连续的三维结构基序，包括两个催化位点，这为该蛋白质提供了令人惊讶的功能复杂性。对阐明 MIF 结构及其在人类和植物疾病中的作用做出了重大贡献，并对植物 MIF 进行了全面的计算机表征。在这些发现的背景下，ANR-DFG 联合提案的目的是研究。申请人结合了人类、植物和寄生虫（蚜虫）来源的 MIF 之间的分子联系，以确定免疫反应调节中潜在的保守功能。他们拥有拟南芥和大麦的比较植物免疫和分子遗传学方面的专业知识，以这种跨物种/界的方法研究 MIF 的功能和结构特征，因此他们代表了一个独特的跨学科团队，结合了 MIF 生物化学方面的深入专业知识，该合作项目将使我们能够首次阐明植物和昆虫 MIF 的作用以及不同领域之间共享与独特基序的功能相关性。将系统地利用 MIF 结构功能谱的跨领域分析，以更好地了解 MIF 在传染病和植物免疫中的机制。此外，该提案还将引发对 MIF 家族免疫逃避机制和进化历史的新研究。 。
