Chemokines are chemotactic cytokines that induce the directed migration of cells by activating specific G protein-coupled receptors. This system of approximately 50 cytokines and approximately 20 receptors plays a particularly prominent role in development, homeostasis and activation of leukocytes in the mammalian immune system. Chemokines determine the nature of the tissue inflammatory response in a wide range of human diseases and represent attractive new therapeutic targets. Chemokines may also attract and stimulate non-immune cells, such as tumor cells, neurons and blood vessels. This meeting will address major unanswered questions in the chemokine field including how Chemokines regulate lymphoid development, how cells sense chemokine gradients, the nature of the chemokine signaling pathway, how Chemokines amplify immunologically-mediated disease, and whether disrupting chemokine signaling can treat or prevent disease. A systems biology approach to chemokine function in vivo will be highlighted and will extend to the regulation and interrelationship of the chemokine system with other regulatory systems in vivo. Directed cell migration is an essential process for normal development, homeostasis and the body's response to infection and cancer. Aberrant cell migration is a critical component of autoimmune and inflammatory diseases. Chemokines and chemokine receptors are the proteins in the body that control the migration of cells. A better understanding of how the chemokine system controls cell movement will lead to new ways of augmenting cell trafficking to fight of infectious diseases, cancer and improve vaccine efficacy as well as inhibit the pathologic recruitment of cells into tissue in autoimmune and inflammatory diseases.

趋化因子是趋化细胞因子，通过激活特定的 G 蛋白偶联受体来诱导细胞定向迁移。这个由大约 50 种细胞因子和大约 20 种受体组成的系统在哺乳动物免疫系统中白细胞的发育、稳态和激活中发挥着特别重要的作用。 趋化因子决定了多种人类疾病中组织炎症反应的性质，并代表了有吸引力的新治疗靶点。趋化因子还可以吸引和刺激非免疫细胞，例如肿瘤细胞、神经元和血管。本次会议将讨论趋化因子领域尚未解答的主要问题，包括趋化因子如何调节淋巴发育、细胞如何感知趋化因子梯度、趋化因子信号通路的性质、趋化因子如何放大免疫介导的疾病，以及破坏趋化因子信号传导是否可以治疗或预防疾病。将强调体内趋化因子功能的系统生物学方法，并将扩展到趋化因子系统与体内其他调节系统的调节和相互关系。定向细胞 迁移是正常发育、体内平衡以及身体对感染和癌症反应的重要过程。异常细胞迁移是自身免疫性疾病和炎症性疾病的关键组成部分。趋化因子和趋化因子受体是体内控制细胞迁移的蛋白质。更好地了解趋化因子系统如何控制细胞运动将带来增强细胞运输的新方法，以对抗传染病、癌症和提高疫苗功效，以及抑制自身免疫性疾病和炎症性疾病中细胞病理性募集到组织中。
