(从左至右:prophase/metaphase/anaphase/telophase ) 当细胞拥有了两个新的细胞核后,下一步将发生的是细胞质的分离(cytokinesis),对于动物细胞来说,细胞膜将直接向内凹陷,直至掐断两个细胞,由于植物细胞的细胞壁存在,植物细胞在进行cytokinesis的时候,是直接在equator的位置上形成新的cellulose cell wall以及plasma mem...

The Cell Theory was formulated in the first half of the 19th century, but only in the late 19th century did the existence of the cell membrane become widely acknowledged. Our understanding of cell membranes improved over time, from the initial proposal of a lipid-based cell membrane to that ...
membrane fluidityofBacillus subtilis. However, it was also reported that rhamnolipids can stabilize the cellular membranes. For example, it was reported that the decrease of membrane fluidity ofStaphylococcus haemolyticusin response to the increaseddiphosphatidylglycerollevel was stopped and the membra...
相关研究结果于2017年11月2日在线发表在Cell期刊上,论文标题为“Membrane Microdomain Disassembly Inhibits MRSA Antibiotic Resistance”。这项研究是在小鼠和金黄色葡萄球菌(Staphylococcus aureus)中开展的。这种研究的重点是直接攻击这些细菌的细胞膜上的被称作脂筏(lipid raft)的微结构域。
In the clinic, a high level of NKG2D ligands’ expression at the tumor cells membrane is correlated with better prognosis and increased NK cell infiltration in the tumor [72]. Interestingly, a recent report demonstrated that CD8 + T cells are able to eliminate MHC-I negative tumor cells...
Safranine O as a fluorescent probe for mitochondrial membrane potential studied on the single particle level and in suspension Authors: Perevoshchikova IV, Sorochkina AI, Zorov DB, Antonenko YN. Journal: Biochemistry (Mosc) (2009): 663 Computer-assisted live cell analysis of mitochondrial memb...
Membrane permeabilisation. Cell permeabilisation is measured by the internalisation of SAv-Cy5 for (a) 4 T1 cells and (b) E. coli. (Left) Histograms showing Cy5+ maximum fluorescence intensity (n = [Math Processing Error]x¯ 6). (Right) Box plot showing median fluorescence inten...
Organic Anion-Transporting Polypeptides are multispecific membrane proteins that regulate the passage of crucial endobiotics and drugs across pharmacological barriers. OATP1B1 and OATP1B3 have been described to play a major role in the hepatic uptake of
