Specific immune responses from NK and CD8(+) cells were involved in the injury to the duct epithelium and play a significant role in the phenotype of experimental biliary atresia.

CD56(-)CD16(+) NK cells with reduced NK activity may be involved in the bile duct damage in BA, and CD16(+) NK cells expressing CX3CR1 may be attracted by and interact with bile ducts expressing CX3CL

「嬰兒膽道閉鎖」指連接肝臟與十二指腸間的膽道完全不通了。當膽道不通時，肝外管腔都封閉，造成膽汁無法運送到腸道，累積在肝臟就會產生肝硬化的可能，若未及早診斷治療甚至會造成肝臟變大且變硬，長久未治療甚至會因肝硬化、肝衰竭而致命，所以嬰兒膽道閉鎖需要及早診斷與手術治療…。關鍵字：嬰兒膽道閉鎖,膽道閉鎖,膽囊,膽汁,黃疸,嬰兒大便卡,經皮肝穿刺檢查,腹部超音波,核磁共振,葛西手術,Kasai,膽道炎,中鏈
