Toll-like Receptor Agonists in Radiation Protection / 中国医学科学院学报

ABSTRACT

Ionizing radiation causes the massive apoptosis of human tissue cells,leading to dysfunction of the gastrointestinal tract and hematopoietic system.Thus,high-efficiency,low-toxicity radiation protection drugs are urgently needed.Toll-like receptor agonists have been developed based on the anti-apoptotic mechanism of tumor cells in recent years,which exert their radioprotective effects by activating downstream pathways,mainly nuclear factor-κB.Here we elucidate several agonists of Toll-like receptors involved in radiation protection,with an attempt to inform the research and development of new radiation protection agents.
