科学家发现精神分裂相关基因位点
科学家发现精神分裂相关基因位点
2019 - 02 - 01
复旦大学类脑智能科学与技术研究院冯建峰团队对来自英美等 6 个国家、20 余所研究机构超过 1 万例影像遗传学数据进行计算分析，通过全脑全基因组范围的 “广泛搜索”，发现与青春期大脑壳核体积相关的基因位点同时也是精神分裂症的风险位点。该成果近日发表于《美国医学会杂志—精神病学卷》。“这项研究证明青春期大脑壳核体积异常和精神分裂症致病风险高度相关。” 冯建峰表示，该发现有望帮助科学家揭示精神分裂症发病机制，为临床症状出现之前的超前干预研究提供新思路。精神疾病防治是当今世界各国面临的共同难题。据报道，在中国，精神疾病已超过心脑血管疾病和恶性肿瘤，成为医疗体系的最大负担。“大脑在不同年龄受不同遗传信息影响，此前的研究未严格控制这一混杂因素，导致重要的遗传信号被‘淹没’。” 论文第一作者、复旦大学类脑智能科学与技术研究院副研究员罗强告诉《中国科学报》，研究团队选取了 14 岁健康青少年脑结构影像数据，同时突破了传统的解剖学脑区划分限制，在全脑全基因组范围内开展无偏的探索性研究，首次找到了青少年大脑结构与基因位点之间最为显著的关联关系。同时针对该结果，研究人员进一步开展了孟德尔随机化分析，发现了一条基因—大脑—精神分裂症的新通路。“这项研究的突破主要基于对来自全球范围的多中心影像遗传学数据进行计算分析，这些全维度标准化大数据的获取，得益于多年来我们在全世界范围内深入开展的国际合作研究。” 冯...

研究发现不健康饮食导致大脑退化
研究发现不健康饮食导致大脑退化
2019 - 06 - 18
和50年前相比，现在人们日常卡路里摄入更多，平均每天高出650大卡，相当于每天多吃了一顿有汉堡、薯条和可乐的套餐，约占男性和女性每日所需食物能量的1/4和1/3。这些多余的卡路里不仅体现在越来越多人圆滚的腰围上，根据澳大利亚国立大学（Australian National University，ANU）的专家提醒，更会对我们的大脑带来“毁灭性”的影响。ANU团队的最新研究显示，由于不健康生活方式，大脑功能衰退可能比我们想象得更早。研究结果近日发表在Frontiers in Neuroendocrinology。根据世界卫生组织的数据，全球约有39%的成人超重，13%的成人肥胖。作为超重和肥胖的常见健康后果之一，2型糖尿病在2030年将影响约10%的成人。众所周知，2型糖尿病与大脑健康受损、认知功能退化有关，神经损伤也是糖尿病的并发症之一。那么，在还没有出现高血糖等符合糖尿病诊断的症状时，神经退行性病变和认知障碍是否也已经处于病理过程中了？又与哪些导致血糖变化的因素有关？研究团队回顾了近200项相关的国际研究，结果表明，即便是非糖尿病人群，由于血糖偏高和肥胖而导致的神经病变也在非常早期就开始了，并且从那时起就开始影响大脑健康和认知功能。比如，一项涉及澳大利亚超过7000人的PATH研究显示，哪怕血糖值尚且在正常范围内，但血糖偏高的人群，大脑中海马和杏仁核普遍萎缩更多，4年内体积约缩小...
