中文摘要
我们已经调查了小鼠和人类粪便样本中涉及的微生物群落,最近开始研究血清样本。在小鼠粪便样品中鉴定出数量最多的细菌类群为拟杆菌门、梭菌门、乳酸杆菌门和Verrucomicrobiales。2月龄和48月龄小鼠的微生物丰度也有显著差异。我们还分析了来自BLSA的18份人类粪便样本,发现普雷沃氏菌属的衰老(AIM 1a,b) (LGG, TGB, LEPS)显著降低。我们正在积极致力于规范小鼠脑脊液和脑的方案提取和序列(AIM 1c)。我们目前也在研究肠道微生物组对促炎细胞因子和肠道通透性(AIM 2)的影响。
英文摘要
We have investigated microbiota community involved in mouse and human fecal samples and recently started working on the serum samples. The most abundant bacterial taxa identified in mouse fecal samples were Bacteroidales, Clostridiales, Lactobacillales, Verrucomicrobiales. Also, there was significant difference in the microbial abundance between 2 month and 48 old mice. We also analyzed 18 human fecal samples from BLSA and found the genus Prevotella was significantly lower in aging (AIM 1a,b) (LGG, TGB, LEPS). We are actively working on standardizing the protocol extract and sequence from CSF and brain in mice (AIM 1c). We are also currently working on the impact of gut microbiome on pro-inflammatory cytokines and intestinal permeability (AIM 2).
