是不是calcium-independent? 在TTX存在的情况下貌似钙通道拮抗剂如Cd2+,Co2+对
EPSC无影响。那么,spontaneous vesicle release不需要钙信号?需要的话钙从哪儿
来?internal release 还是基础水平的(nM)钙就够了?
有引文推荐最好,多谢多谢!!

STOCKHOLM (Reuters) - Three U.S.-based scientists won the 2013 Nobel
medicine prize on Monday for their work on how hormones and enzymes are
transported within and outside cells, giving insight into diseases such as
diabetes and Alzheimer's.
Americans James Rothman, 62, Randy Schekman, 64, and German-born Thomas

来自主题: Biology版 - endocytosis 调控因子
好建议,记下了。
"During vesicle uncoating, primary endocytic vesicles may acquire Rab5, a
small GTPase involved in transport to early endosomes and in early endosome
docking and fusion. Primary endocytic vesicles are targeted to and fuse with
early endosomes expressing phosphatidylinositol(3)-phosphate, PI(3)P, in a
process dependent on Rab5 effector proteins and early endosomal SNAREs."
我觉得抑制endocytosis相对简单。比较困难的是还想找到有哪些靶点,通过对其调节
可以增加endocytosis呢?

Cellular competency (natural transformation) refers to the active uptake of
free (extracellular) DNA across the cell wall and cell membrane(s) using
cellular machinery designed to facilitate the process (Dubnau, 1999; Lorenz

is often sensitive to environmental cues (Molin and Tolker-Nielsen, 2003).

Synaptotagmin之死
作者:llybt 提交日期:2004-05-28 09:35
Synaptotagmin之死
Synaptotagmin现在是个平常的人,双手双脚,双眼双耳,毫无过人之处。
近日,却惹上了官司。
至于结果,他将被赐鸩而死。
明天,清早鸡鸣之刻,就是行刑之时。
三更已过,还有几个时辰。
此刻他万念俱灰,端坐在Vesicle Membrane上,一如既往。Vesicle这个大热气球飞
来飞去,不小心撞上满是废油污染的海面后,满肚子的坏水就往外流。于是Synaptotagm
in仿佛等待拯救的海鸟一般,周身不能动弹,耷着脑袋数沙子。
不过大多数时候,他倒是清闲,看周围的繁忙交通,人群,车辆来来往往。它们和
我一样,都是过客,他想,而且我比它们看得更开通。然后就是笑。
Synaptotagmin虽平庸,却不明白为何Complexin会和他过不去——更可笑的是那理

If they are really vesicles and extremely painful, then the chance is high
for shingles. But you still need to go to see a doctor. Go to ER if you have

For life to begin, three conditions had to be met. First, groups of
molecules that could reproduce themselves had to come together. Second,
copies of these molecular assemblages had to exhibit variation, so that
some were better able to take advantage of resources and withstand
challenges in the environment. Third, the variations had to be
heritable, so that some variants would increase in number under
favorable environmental... 阅读全帖
