Sterols, such as cholesterol ... act allows for the formation of membrane domains—self-assembling structures that are believed to organize proteins in cell membranes. The work tests and revises ...

This test showed that cholesterol is very important for protecting cell membranes from light-induced damage," explains the IQ-USP professor. However, during membrane protection, these sterols are ...

The first step of successful infection by any intracellular pathogen relies on its ability to invade its host cell membrane. However, the detailed structural and molecular ... KMP-11 can form ...

In eukaryotes, sterols are crucial for signaling and regulating membrane fluidity, however, the mechanism governing cholesterol production and transport across the cell membrane in bacteria remains ...

Using fluorescent analogs of cholesterol and quantitative fluorescence microscopy, we have recently measured the transport kinetics of sterol between plasma membrane (PM), recycling endosomes (REs) ...

Nutrient starvation initiates cell cycle exit and entry into quiescence ... and was accompanied by a shift of the cellular lipid profile from membrane towards storage lipids, driven by a ...

Cell polarity is essential for generating diverse cell functions. The underlying mechanisms of how a cell establishes, maintains, and changes its polarity are poorly understood. Recently, sterol-rich ...

Intracellular sterol distribution mediated by lipid transfer proteins (LTPs) is crucial for membrane function. LTPs anchored at membrane contact sites (LAMs), new members of LTPs in the StARkin ...
