While research has determined that there is no association between having AMD and then developing Alzheimer's or dementia, ...

A plasma membrane is permeable to specific molecules that a cell needs. Transport proteins in the cell membrane allow for selective passage of specific molecules from the external environment.

This takes place when molecules diffuse across the cell membrane by travelling through specific transport proteins. It occurs down a concentration gradient - molecules move from an area of high to ...

The current cisternal maturation model proposes that these vesicles are transport vehicles for Golgi enzymes rather than for protein cargo. Retrograde vesicles that travel backward through the ...

A team of researchers at the Max Planck Institute for Medical Research made a striking discovery—a protein with contradictory properties: a strongly negative charge, yet a very high propensity ...
