586. 斯坦福大学揭秘mRNA疫苗引发心肌炎机制

from 知为谁 · host 知为谁

这项由斯坦福大学进行的研究揭示了mRNA新冠疫苗引发极少数年轻人出现心肌炎的具体生物学机制。科学家发现,疫苗偶尔会诱发一种由巨噬细胞和T细胞共同参与的双阶段免疫反应,导致体内产生过量的炎症信号分子,进而对心脏组织造成暂时性损伤。尽管此类副作用极其罕见且症状通常较轻,研究人员仍通过实验证实,阻断特定的蛋白质可以减轻这种炎症。此外,研究还提出一种源自大豆的天然化合物染料木黄酮可能具有预防此类心脏损伤的潜力。该发现不仅为提升疫苗安全性提供了新思路,也重申了疫苗在预防重症方面远比感染病毒本身更具优势。内容来源:https://www.sciencedaily.com/releases/2025/12/251227082716.htm
