  Background & objectives: Hydaticosis is a zoonotic helminthic disease of human and other intermediated hosts in which larval stages of the tapeworm Echinococcus granulosu transfect human. The liver and lung are the host tissues for the hydatid cyst . It is unknown which mechanisms are involved in infertility of the cyst and suppression of the fertile cyst. This study was aimed to evaluate the expression of the apoptosis inducing-ligands such as TRAIL and Fas-L in germinal layer of the cyst and human normal tissue surrounding the cyst that is one of the unknown host innate immunity mechanisms against the hydatid cyst.

  Methods: In this study, four isolated hydatid cysts were used which had been diagnosed in patients by radiography and parasitological examination in Mashhad Ghaem hospital. Furthermore, the germinal layer of the cyst and accompanied normal peripheral tissues were separated by scalpel in sterile conditions. After homogenization, expression of TRAIL and Fas-L genes were studied by semi-quantitive RT-PCR method.

  Results: The TRAIL and Fas-L showed significant higher level expression in germinal layer of infertile cyst than the fertile cyst and host normal tissues.

  Conclusion: The host tissue-induced apoptosis of germinal layer of the fertile cysts is probably one of the infertility mechanism in patients with hydaticosis
