Research Progress on the Mechanism of Radiation Tolerance of a Tardigrade
WEI Yirui, LI Lei*, ZHANG Lingqiang*
Space radiation damage is a critical medical issue that constrains human deep-space exploration and long-term on-orbit residence. In various nuclear-related work environments, ultra-high radiation poses a severe hazard to human, and a substantial threat to personnel health and safety. Tardigrades, as unique multicellular organisms, have attracted considerable attention in biological research for their exceptional stress resistance. This review focuses on the radiation tolerance characteristics of tardigrades, detailing the latest progress in the research on the ultrahigh radiation tolerance mechanism of tardigrades, as well as its significance and potential application value in fields such as biomedicine and radiation protection.
