新基因编辑系统助免疫细胞抵抗HIV
新基因 编辑系统 免疫细胞 HIV
2016/12/5
近日《细胞通讯》杂志上的一篇科学论文，为基因编辑技术的发展再注一笔。一种新的基因编辑系统，帮助研究人员找到了可使人类免疫细胞对抗艾滋病病毒（HIV）感染的基因变异。在人类对抗艾滋病的漫长征途中，基因编辑技术开始发力。此项成果归属于美国加州大学旧金山分校及其附属格莱斯顿研究所的研究人员。该团队使用CRISPR/Cas9技术，建立了一个高通量细胞编辑平台，能够测试不同基因变异对免疫细胞对抗HIV的影响...
Penn Study Models How the Immune System Might Evolve to Conquer HIV
Penn Study Models Immune System HIV
2016/8/1
It has remained frustratingly difficult to develop a vaccine for HIV/AIDS, in part because the virus, once in our bodies, rapidly reproduces and evolves to escape being killed by the immune system.“Th...
黏膜细胞凋亡后可能“伤及自身” 诱发免疫和过敏性疾病
黏膜细胞凋亡 伤及自身 诱发免疫 过敏性疾病
2016/3/8
花瓣凋零，还能“化作春泥更护花”。不过，自然界也不尽是这种良性循环。日本一项新研究发现，动物的黏膜细胞在凋亡后，可能刺激免疫系统“过度反应”，诱发自身免疫性疾病和过敏性疾病。肠道、皮肤等处的黏膜被上皮细胞覆盖，内部产生新细胞的同时，老细胞会凋亡剥落，并随着粪便、痰或皮肤污垢被排至体外。此前并未发现这些“被淘汰”的细胞会对机体产生哪些影响。
日研究发现艾滋病病毒感染新机制
艾滋病病毒 隧道纳米管
2016/2/22
日本理化学研究所日前发表公报称，研究人员发现了艾滋病病毒进行细胞间感染的新机制，并发现一种化合物能遏制这种感染。这有望促进开发治疗艾滋病的新药物。此前，研究人员发现艾滋病病毒的细胞膜会形成被称为“隧道纳米管”的微小管道，从而使得细胞间能够迅速进行物质交换，病毒在此过程中得以传递，但一直未能弄清“隧道纳米管”的形成机制。
Age-Related Cognitive Decline Tied to Immune-System Molecule
Age-Related Cognitive Decline Tied Immune-System
2015/7/13
A blood-borne molecule that increases in abundance as we age blocks regeneration of brain cells and promotes cognitive decline, suggests a new study by researchers at UC San Francisco and Stanford Sch...
Safe strep throat vaccine closer to reality（图）
strep throat vaccine the human immune system
2014/7/4
Researchers are one step closer to developing a safe vaccine against strep throat, which is responsible for more than 700 million infections and 500,000 deaths each year.
科学家开发自体免疫疾病新疗法
科学家 自体免疫疾病 新疗法
2014/6/20
美国国家卫生研究院科学家2014年6月18日说，他们开发出对自体免疫疾病的一种新疗法，可在动物体内诱导出有效抑制致病炎症细胞、而不会影响正常免疫反应的免疫调节细胞。如果这一技术能成功应用于人类，有可能帮助人类最终攻克自体免疫疾病。人类有许多慢性病，像多发性硬化症、I型糖尿病和类风湿性关节炎，是由免疫系统以某种方式“滥杀无辜”引起的，这种免疫系统伤害自身组织和器官的疾病被称为自体免疫疾病。目前，自体...
药片激活疫苗新技术获德国创新奖
药片激活疫苗 德国 创新奖
2014/4/24
一些疫苗需要多次注射才能起效果，如乙肝疫苗、狂犬病疫苗等。德国科学家发明了一种新技术，只需一次注射，以后可服用药片来逐步激活疫苗。该发明日前获得德国“生物地区工作组”2014年创新奖。
