简要总结
The main objective of this study is to characterize the regulatory immune response induced by hookworm in an infected Vietnamese rural population from the periphery of HCM, evolution after infection treatment and during potential naturally reinfection.
详细描述
Population: 20 healthy adults (18-65 years) infected and non infected by Hookworm will be recruited and treated according to Good Clinical Practice recommendations.
Allergy will be excluded by skin prick tests. Amount and phenotype of Treg will be explored at several time points. Subsequent culture with environmental antigen will be performed on cryopreserved cells.
