Dave deBronkART:所有病人应彼此交流
当Dave deBronkART了解到他得了一种罕见的晚期癌症,他在网上向和他一样的一群病人求助,并且找到了一种甚至他自己的医生都没听过的治疗方法。这救了他的命。 现在他号召所有的病人彼此交流,了解自身的健康数据,使医疗事业在每个e-病人的基础上变得更好。

抗原提呈和树突状细胞 - Ira Mellman PART 2
本视频由科普中国和生物医学大讲堂出品
早在100多年前,科学家就已经发现,免疫反应是由先天性和适应性免疫两个系统构成。而负责连接这两部分免疫反应的细胞类型,是最近才发现的树突状细胞。树突状细胞具有检测保守微生物产物的能力,可以激活细胞的先天免疫反应,并捕捉到广泛多样的微生物抗原抗体,也可以激活适应性免疫反应。抗原提呈和树突状细胞的独特能力,反映了细胞生物学的一系列显著的特化作用。
Ira Mellman (Genentech) PART 2: Antigen Presentation and Dendritic Cells
The immune response integrates two distinct systems of innate and adaptive immunity discovered over 100 years ago. Linking these two arms of the immune response is the task of a comparatively recently identified cell type, the dendritic cell. Dendritic cells have the capacity to detect the conserved microbial products that activate cells of the innate immune response and capture the dramatically wider diversity of microbial antigens to prime antibody and T cell responses characteristic of adaptive immunity. The unique capacity of dendritic cells for antigen processing and presentation reflects a series of remarkable specializations of basic principles of cell biology.

剪接体的结构和动力学 - Melissa Moore PART 2
本视频由科普中国和生物医学大讲堂出品
本节课Melissa Moore讲述了,剪接体的成分和在每个工作周期中的剪接体。穆尔还解释了如何利用荧光蛋白标签和全反射显微镜的创新,使她和她的同事们能够更好地理解复接机器的有序组装与功能。
Melissa Moore (U. Mass/HHMI) PART 2: Spliceosome Structure and Dynamics
Moore goes on to describe the cellular splicing machine, the spliceosome, in greater detail in PART 2. She lists the components of the spliceosome and where each works in the spliceosome cycle. Moore also explains how the innovative use of fluorescent protein tags and total internal reflection microscopy has allowed her and her colleagues to better understand the ordered assembly and function of the complex splicing machine.

Photoreceptors and Image Processing PART 1A - Jeremy Nathans
本视频由科普中国和生物医学大讲堂出品
Jeremy Nathans (Johns Hopkins) PART 1A: Photoreceptors and Image Processing
In this set of lectures, Jeremy Nathans explores the molecular mechanisms within the retina that mediate the first steps in vision. The first lecture focuses on the structure of the light sensing receptors, the intracellular signals that are triggered by light absorption, and the ways in which the retina extracts information from a complex scene.
