瑞典近600名婴儿的追踪研究显示,出生第一周出现强烈“播种”免疫反应(干扰素γ等炎症分子水平高)的婴儿,到1岁时患湿疹或食物过敏的比例达39%,而反应较弱者仅12%。研究者认为,肠道中拟杆菌属细菌的丰度会驱动这种强烈反应,而双歧杆菌和喂养方式(母乳或配方奶)则影响后续免疫走向。专家表示,这一发现有望用于为婴儿开发个性化预防手段,但目前还远不足以改变对家长的喂养建议。
原文开头
The strength of immune response that newborns have could determine how their immune system develops, and the microbiome seems to play a role in this, finds Carissa Wong BABIES who have a strong immune reaction in the first week of life appear to have triple the risk of developing an allergy or eczema by age 1, compared with those who don’t. But the long-term impact of this early immune response, now defined for the first time, seems to be modulated by the microbiome and how babies are fed. “If you ask 100 immunologists, they would say that immune development begins at birth and continuously develops over time, without discrete phases,” says Petter Brodin at Imperial College London. …
