The cell membrane is a barrier that controls the exchange of compounds and information between the outer and inner parts of the cell. In order to achieve this function, cell membranes contain embedded membrane proteins that play different roles. Several of families of membrane proteins have been ...
Excitation–contraction coupling describes transduction of cell membrane depolarization into mechanic shortening of the muscle fiber. Cell membrane depolarization is stimulated by nerve impulses arriving at the neuromuscular junction. Following the generation of a sufficient motor endplate potential, depolarizatio...
The interfollicular epidermis of the skin consists of KCs, maintained by EpdSCs, and various immune cells. These SCs are attached to the basement membrane and give rise to transient amplifying cells capable to differentiate into corneocytes. In this epidermal niche, cell death is actively suppresse...
Cells communicate with each other through secreting and releasing proteins and vesicles. Many cells can migrate. In this study, we report the discovery of migracytosis, a cell migration-dependent mechanism for releasing cellular contents, and migrasomes,
AbstractObjective:Transformation from normal cells to malignant cells is the basis for tumorigenesis. While this cell transformation is known to result from aberrant activation or inactivation of associated genes, these genes have not yet been fully identified. In addition, DNAJs, proteins with a J ...

For example, Dahoumane et al. set up an innovative approach using living cells of the Chlamydomonas reinhardtii microalga to obtain silver–gold alloy NPs. Their study showed that adding silver and gold salts to the algal culture would cause cell sedimentation, due to the internalization of the ...

Structure of Prokaryotic Cells Prokaryotic cellshave a cell membrane, cell wall, cytoplasm and ribosomes. However, prokaryotes have anucleoidinstead of a membrane-bound nucleus. Gram-negative and gram-positive bacteria are examples of prokaryotes, and you can tell them apart because of differences in...
