However, the constituents of a living membrane are far from being well equilibrated. The living cell membrane actively maintains a trans‐bilayer asymmetry of composition, and its constituents are subject to a number of dynamic processes due to synthesis, lipid transfer as well as membrane traffic ...
The complex, multiscale nature of the process hinders its theoretical understanding, especially at the molecular level. The present article aims to contribute to the fundamental picture of the process by the molecular modeling of its nanoscale analogue and complements the picture by laboratory ...
In fact, these traits are precisely what make a cell a cell. What Defines a Cell? Figure 1: Transport proteins in the cell membrane A plasma membrane is permeable to specific molecules that a cell needs. Transport proteins in the cell membrane allow for selective passage of specific ...
Conventional live-cell optical microscopy fails to visualize polarity site formation in the crowded cell membrane environment because of its limited resolution. We have used advanced live-cell imaging techniques to directly observe the localization, assembly, and disassembly processes of cell polarity ...
All modern cells are bounded by cell membranes best described by the fluid mosaic model. This statement is so widely accepted by biologists that little attention is generally given to the theoretical importance of cell membranes in describing the cell. T
Cellulose is the major component in wood, which is present universally in plant cell walls and provides mechanical strength to the plant. Cellulose accounts for about 20 % and 50 % of the primary and secondary cell walls in higher plants, respectively. Membrane-bound cellulose synthase enzyme com...
Cell Theory was first formulated in the XIXthcentury, almost nothing was known about the cell membranes. It was not until well into the XXthcentury that the existence of the plasma membrane was broadly accepted and, even then, the fluid mosaic model did not prevail until the 1970s. How ...
Fig. 2: Overall structure of the PBS complex viewed in electron micrographs of cell sections and isolated complexes. a, b Representative TEM images of A. panamensis. The white arrows indicate the paddle-shaped particles (front view), and the black arrows indicate the rod-shaped particles (side...
The cover picture shows a novel helix-stabilized, cell-penetrating peptide. There are a lot of "helices", like the ladies' tresses shown in the background image, that exist in nature and even in our bodies, such as micro helices (DNA, proteins, etc.), which are present as ubiquitous ...
Molecular imaging allows the non-invasive assessment of membrane transporter expression and function in living subjects. Such technologies have the potential to become diagnostic and prognostic tools, allowing detection, localization, and prediction of response of tumors and their metastases to therapy. Bey...
