宇宙飞行对航天员免疫系统的影响

Effects of spaceflight on function of immune system in astronauts

目的概述近年来有关宇宙飞行影响航天员免疫系统功能的研究进展。

Objective To summarize the works of effects of space environments on function of immune system in astronauts .

资料综合论述了宇宙飞行对航天员免疫系统功能的影响及其可能机制。

Literature synthesis Influences of space environments on immune function of astronauts and its mechanisms were summarized and discussed .

由于太空实验的数量有限且重复性差，所以，目前的研究结论都是初步性的，对于宇宙飞行对航天员免疫系统的确切影响还有待进一步研究。

At present , the times of space experiments are limited and its repeatability is low , so the conclusions are preliminary and further investigations are needed .

结论宇宙飞行可影响航天员免疫系统功能，导致细胞免疫功能减低，但是，体液免疫功能变化不明显。

Conclusions Spaceflight might affect the immune function of cosmonauts and lower the cell immune response , however , it had little influence on humoral immune response .

目前，对于宇宙飞行导致航天员免疫系统功能改变的可能机制，主要集中于太空复合因素以及由其引起的神经-内分泌系统改变对免疫系统的直接和间接影响。

For the moment , most investigations suggest that the mechanism of changes of immune function is mainly related to space environments and variations of neuroendocrine system induced by space factors .
