终于上班了。不用每天向春节期间亲朋好友解释“你到底在干啥啊,过春节都不休息!”
亲朋好友如相问,我还在写国自然。
受朋友们委托,我们最近一直在查询美国基金资助的情况,并提供了部分基金的摘要。
今天看到的一项(系列)基金让我们深有感触,所以特意分享出来。
尽管医学得到了充分发展,但面对很多疾病,人类仍然束手无策。其关键是人类对这些疾病尚不了解,特别是未能充分找到对疾病发生发展的核心生物标记物(Biomarker Core)。
在这种背景下,美国启动了一系列基金资助,用于生物标记样本的收集和研究。
即,通过标准化地收集、正确处理与存储研究对象(睡眠障碍患者)的样本(血液、尿液及其他样本),为研究人员提供支持,来筛选和确定疾病的核心生物标记。
该项目迅速应用推广到了各类疾病中。到目前,已经有221项研究获得了收集样本的基金支持。我们对这221项基金进行了大数据分析。
希望能够给您一些启发和帮助。
核心生物标记

热点分类研究
在核心生物标记研究中,项目的重点关键词依次为:老年性痴呆、质谱、生物医学研究、烟草、血管病、HIV-1、肾病、小分子等。
最常用的方法学是质谱技术。
主要与老年性痴呆、病理标记物、烟草、翻译修饰、生物标记、ELISA等相关。
这项持续了数十年年的基础工程,用于探索未知、也未要求有明确预期结果的基金项目,到目前已经达到了37项在研课题。
研究重点也稍有改变。
PET成像、质谱、人工智能和小分子成为是最重要的研究方向;轻度认知障碍、血管病、帕金森病等则成为目前最重点研究的疾病,并且侧重在早期(诊断)方面。
PET影像
已经成为生物标记最有用的研究方法。目前主要用于Apo E、轻度认知障碍、脑血管病、机器学习等。
我们提供一份威斯康辛大学老年性痴呆研究中心(ADRC)的课题摘要,供同仁们参考借鉴。
PROJECT SUMMARY
BIOMARKER CORE (CORE G) The BIOMARKER CORE(BMC) of the Wisconsin Alzheimer's Disease Research Center (ADRC) represents the capability and infrastructure for peering into the brain in vivo to obtain biological markers of Alzheimer's disease (AD) and related disorders and non-disease-specific qualities characterizing brain health and resilience.
Since the pre-clinical time frame of AD is a major emphasis of the ADRC, and since it is increasingly understood that AD pathology occurs well before its symptoms, the charge of this core is to provide the necessary capabilities, tools, and infrastructure to investigators to characterize as accurately as possible the early in-vivo changes of AD, effect of risk and resilience factors, and effect of prevention strategies on relevant biomarkers.
The core will focus on collecting, quality checking, and curating several types of AD-relevant biomarkers including
a) markers indicative of AD - defined by amyloid plaques and neurofibrillary tangles, and ascertainable by molecular PET imaging or cerebrospinal fluid (CSF) assays;
b) markers of cerebrovascular diseases - the second most common etiology (or etiologies) of cognitive decline and ascertainable by new MRI methods;
c) markers of other neurodegenerative diseases as they become available via CSF or PET;
and d) markers of general brain health including synaptic density, neuronal injury, atrophy, connectivity, inflammation, and blood flow that are possible through PET, MRI and CSF modalities.
To meet these goals, we will accomplish the following aims:
Aim 1: Obtain biological markers of AD's hallmark neuropathological features - amyloid plaques and neurofibrillary tangles with CSF and/or molecular PET imaging.
Aim 2: Collect biomarkers of concomitant features, such as vascular disease, inflammation, and neuronal death.
Aim 3: Develop method for interpreting biomarker readouts, particularly for Amyloid (A), tau (T) and neurodegeneration (N).
Aim 4: Support ADRC investigators with infrastructure and analytic support.
Aim 5: Share images, fluid, and derived data with the National Alzheimer's Coordinating Center (NACC), local investigators, and other qualified investigators throughout the world.
Aim 6: Expand the Center's biomarker capability, including a) adopting new methods and modalities in this fast-changing field, and b) for harmonizing previously collected data or multi-site data with current or future collection methods.
The BMC will work interactively with the other ADRC cores to serve the needs of the ADRC investigators as efficiently as possible and deliver high quality data to NACC and other users so we, as a field, can come to answers faster in detecting and intervening effectively in AD.
这项研究可以被其他疾病所借鉴。
随着分子生物学研究发展,基于生物标记的临床表型和精准医疗研究课题研究方兴未艾,这项课题很值得借鉴。
我们也看到,在生物标记研究中,特别多的课题关注了老年性痴呆研究。
老年痴呆症(Alzheimer’s disease, AD)是在导致人类死亡的主要原因之一,并影响全球影响约5000万人的健康和生活。
与其他主要疾病不同的是,目前尚无批准的任何疗法来减缓或逆转AD。
为了攻克AD,从1998年起至今,全球累计投入超过6000亿美元的研发费用。包括辉瑞、礼来、罗氏、默沙东、阿斯利康、默克等知名制药公司,均在AD药物研究中投入过巨额资金,但均宣布失败或者不得不终止研究。
针对AD治疗药物研发失败的主要原因是,人类其实并没有真正了解AD。也因为此,针对AD的很多研究回到了起点:继续从生物标记开始,并且特别关注临床前样本的收集。
