血吸虫及其相应宿主之间存在共同抗原可能是血吸虫逃避宿主免疫攻击的机制之一。本文作者已证实,血吸虫DNA中存在其宿主的MHC序列。为证实曼氏血吸虫成虫和尾蚴的MHC序列是否源自其宿主,本文作者进行了以下实验。 The common antigen between schistosomes and their corresponding hosts may be one of the mechanisms by which schistosomiasis evades the host immune attack. The authors have demonstrated that the host’s MHC sequence is present in the schistosome DNA. To confirm whether the MHC sequence of Schistosoma mansoni adult and cercariae originated from their host, the authors conducted the following experiments.
