1288-抗生素引发的婴儿肠道真菌失调与哮喘风险研究

from 聊聊Sci

这项研究揭示了婴儿早期使用抗生素如何通过改变肠道真菌群落(mycobiome)影响免疫发育。研究发现,抗生素治疗会导致肠道内马拉色菌(Malassezia spp.)异常扩张,这种真菌的增加与婴儿微生物群发育迟缓及过敏性疾病风险升高密切相关。通过小鼠模型实验,科研人员证实了马拉色菌的定植会诱发肠道免疫失调,并显著加剧呼吸道对过敏原(如屋尘螨)及呼吸道合胞病毒(RSV)的炎症反应。这种免疫病理过程部分依赖于嗜酸性粒细胞的参与。该成果强调了肠道真菌在“肠-肺轴”中的关键作用,并为预防儿童哮喘等早期过敏性疾病提供了新的干预思路。References:van Tilburg Bernardes E, Glatthardt T, Gutierrez M W, et al.
