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 ...

A recent study published in Proceedings of the National Academy of Sciences of the United States of America (PNAS) describes a unique organization of mitochondria in photoreceptor cells that may be ...

Mitochondria are often called the powerhouses of the cell. ... Unlike other organelles (miniature organs within the cell), mitochondria have two membranes, an outer one and an inner one.

The analysis of changes in mitochondrial membrane potential (MMP) that can occur during apoptosis provides precious information on the mechanisms and pathways of cell death. For many years, the ...

The cell’s mitochondria (in green) gather around the invader and begin to shed vesicles (green bubbles) made of mitochondrial outer membrane. Sometimes, the vesicles can form elaborate ...

One feature of eukaryotes is a complex endomembrane system, comprised of the various membranes that are suspended inside the cytoplasm of a eukaryotic cell. These critical membranes create different ...

A new study reveals that the protein MTCH2, which is essential in a variety of cellular processes, is responsible for shuttling various other proteins into the membrane of mitochondria. The ...

Mitochondrial membrane potential, an indicator of mitochondrial function, is perturbed in many diseases, including cancer and neurodegenerative diseases, but difficult to measure noninvasively ...

“The mitochondrial permeability transition pore (MPTP) is a megachannel in the inner mitochondrial membrane that opens in response to high matrix Ca2+ and oxidative stress,” the authors noted.

In a step toward treating mitochondrial diseases, researchers in the Netherlands have successfully edited harmful mutations ...
