Background:
The neglected disease cystic echinococcosis is caused by larval Echinococcus granulosus flatworms, which form bladder-like hydatid cysts in liver, lungs, and other organs.
Sources Of Data:
Published literature.
Areas Of Agreement:
Establishing larvae are susceptible to antibody-dependent killing, as attested by successful animal vaccination, whereas once established they are partially protected by the so-called laminated layer. Host responses are Th2 dominated, with a Th1 component. Diagnostic antigens from cyst fluid are known, but responses appear absent in one-fifth of patients.
Areas Of Controversy:
Is evasion mainly based on induction of Th2 or regulatory responses by the parasite?
Growing Points:
The parasite induces regulatory responses. The laminated layer has immune-regulatory properties.
Areas Timely For Developing Research:
Develop tools for functional genomics; characterize immunologically interesting proteins suggested by genomic information; analyse infection in broader context of granulomatous responses; identify molecules secreted/excreted by intact larvae/cysts towards their outside, including diffusible immune-regulators.
