Hepatitis: Liver failure attributable to compromised blood supply

In severe cases, a viral hepatitis infection can result in liver failure. A team from the Technical University of Munich (TUM) has now discovered that immune cells attack cells in the vascular system, which disrupts the liver's ...

Diffusible guidance molecule that divides the brain

Boundaries between different regions of the brain are essential for the brain to function. Research to date has shown that molecular machinery located at the cell membrane, such as cell adhesion molecules, are responsible ...

Cancer

Pushing closer to a new cancer-fighting strategy

A molecular pathway that's frequently mutated in many different forms of cancer becomes active when cells push parts of their membranes outward into bulging protrusions, Johns Hopkins researchers report in a new study. The ...

New information on the pathological mechanisms of Alzheimer's disease

Researchers at the University of Helsinki have discovered a mechanism by which harmful tau protein aggregates are transmitted between neurons. Alongside amyloid plaques, tau aggregates in the brain are a significant factor ...

New contact lens to treat eye injuries

A new therapeutic contact lens that acts as a bandage for eye surface injuries being developed by QUT researchers could soon fast track the healing of previously difficult to treat corneal wounds.

Reproducing pediatric kidney disease from human iPS cells

Scientists in Japan have found a "skeleton key" for congenital kidney disease research. Using iPS cells generated from the skin cells of a patient with a nephrin mutation, Kumamoto University scientists have successfully ...

Cell membrane

The cell membrane (also called the plasma membrane or plasmalemma) is the biological membrane separating the interior of a cell from the outside environment.

It is a semipermeable lipid bilayer found in all cells. It contains a wide variety of biological molecules, primarily proteins and lipids, which are involved in a vast array of cellular processes such as cell adhesion, ion channel conductance and cell signaling. The plasma membrane also serves as the attachment point for both the intracellular cytoskeleton and, if present, the extracellular cell wall.
