Abstract:

文昌鱼不仅对于进化学的研究至关重要,在比较免疫学研究中也是一种重要的模式生物.研究文昌鱼免疫相关组织、细胞和基因对了解脊椎动物免疫防御系统的进化十分重要.本文利用电子显微镜对文昌鱼免疫相关组织和细胞的超微结构进行了研究.同时,本文还采用原位杂交方法对文昌鱼中与脊椎动物免疫相关基因同源的基因TLR1,C1Q,ECSIT,SoxC,DDAHa和NOS的表达模式进行了研究.结果显示,在文昌鱼免疫防御过程中,其表皮、腮和肠道上皮可能起重要作用;在体腔和淋巴隙中存在的巨噬细胞可能是文昌鱼体内起重要免疫功能的细胞;TLR1,C1Q,ECSIT,SoxC,DDAHa和NOS的表达模式说明这些基因可能在免疫防御过程中起作用.
