Four genes encoding these 8-kDa-subunits have been identified from E. granulosus. In this study we isolated five genes encoding 8-kDa-subunits of AgB from Echinococcus multilocularis. Sequence comparison of isolated cDNA clones demonstrated that one of these five clones was completely identical to EmAgB8/1 which had been isolated previously by our group, and three of them were 94.5, 90.8, and 91.9% homologous to E. granulosus antigen B 8-kDa subunit genes, EgAgB8/2, EgAgB8/3, and EgAgB8/4, respectively. The remaining clone shared 51–58% homology with the nucleotide sequences of AgB genes. Gene-specific RT-PCR and Western blot analyses revealed that these genes were expressed in a developmentally regulated manner in E. multilocularis vesicles, protoscoleces, and immature adult worms. Possible functions of different expression manners are also discussed., Academic Press, Mamuti, Wulamu ; Sako, Yasuhito ; Xiao, Ning ; Nakaya, Kazuhiro ; Nakao, Minoru ; Yamasaki, Hiroshi ; Lightowlers, Marshall W. ; Craig, Philip S. ; Ito, Akira, Experimental Parasitology, 113(2), 2006, 75-82 \nauthor, text, application/pdf}, pages = {75--82}, title = {Echinococcus multilocularis: developmental stage-specific expression of Antigen B 8-kDa-subunits}, volume = {113}, year = {2006}, yomi = {イトウ, アキラ} }
