Hemifusomes are fused vesicles, or sacs of fluid, that were previously unknown to exist inside cells. They were discovered ...

Under a traditional, light-based microscope, it’s impossible to image something smaller than the wavelength of light that the microscope uses, which is around 250 nanometers, explains Brian ...

The polarity marker determines the polarity site, and with membrane vesicle transport toward it, site-specific growth (polarity growth) is achieved. However, when the plasma membrane elongates due ...

Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike ...

Scientists have used cryo-electron microscopy to observe how lipids and proteins at the plasma membrane interact and react to mechanical stress.

A tympanic membrane retraction is a condition where the tympanic membrane, or eardrum, gets pulled toward the middle of your ear. Here's what you need to know about the condition.

The plasma membrane is a two-dimensional compartment that relays most biological signals sent or received by a cell. Signalling involves membrane receptors and their associated enzyme cascades as ...

Similar to a small cut that heals itself after a short time, individual cells in our body suffer "wounds" in their protective layer, the cell membrane, every day and have to repair them again.

Recurrent appearance of MHCII clusters can be observed indicating dynamic exchanges of MHCII between the virus-interface and the remaining plasma membrane. Credit: Nature Communications (2025).

Cell membranes play a crucial role in maintaining the integrity and functionality of cells. However, the mechanisms by which they perform these roles are not yet fully understood. Scientists from the ...
