    免疫系统的起源与进化的研究是当代免疫学研究热点,文昌鱼是研究脊椎动物起源和演化的活化石。本研究依靠本实验室在高通量筛选技术、免疫遗传学和分子免疫学研究方面的优势,拟对多个文昌鱼免疫相关基因在胚胎和成体中的表达模式和功能进行分析,然后与其它物种的免疫基因做横向比较,从而揭示脊椎动物免疫系统的起源和演化。目前中方实验室已获得了23095条中国文昌鱼的cDNA序列,未来还将进行更大规模的cDNA测序,依靠这种高通量技术将得到70-100个具有重要参考意义的免疫相关基因,下一步我们会会深入分析这些基因在文昌鱼中表达模式及其编码蛋白的功能。但是,由于不能解决文昌鱼驯化和胚胎日常获取等世界性技术难题,中国文昌鱼目前还不是大规模研究基因表达谱和功能的理想模型。相反,目前法方研究团队不但在免疫和胚胎发育研究方面具有深厚的造诣,更重要的是在地中海文昌鱼人工驯化繁育、胚胎每日获取等技术上取得了巨大突破。 The present project aims to draw a general view of how the immune-related genes are expressed during amphioxus embryonic development.Our approach will provide an integrated representation of the ontogenesis and phylogenesis of a prototypical immune system.At present 23095 cDNA clones of six libraries from the Chinese amphioxus(B.belcheri),were sequenced in chinese laboratory,and a larger cDNA sequencing project is going on in the chinese laboratory.This high throughput approach allows to isolate about 70-100 genes orthologous to genes that are directly or indirectly implicated in vertebrates immune system.After that,expression profile and protein function of these genes would be carried out in chinese laboratory.However,the Chinese amphioxus species is not the best model for gene expression studies of a high number of genes due to the difficulty to obtain embryos.On the contrary,the research team in France has developed advanced technical approaches which are very important concerning the amphioxus model(particularly the manual induction of daily spawnings in captivity)with the Mediterranean amphioxus species(B.lanceolatum).So this cooperation could greatly facilitate our study on amphioxus immune system and help to transfer the related techniques from the france laboratory to the chinese laboratory.The present project has three major aims:1)Cloning of the homologous cDNAs of immune related genes of B.belcheri in B.lanceolatum;2)In situ hybridization experiments on different developmental stages of B.lanceolatum of all the immune-related amphioxus genes;3)attempts to develop primary cell culture from B.lanceolatum.
