The histological appearance is primarily the result of two processes: enzymic digestion of the cell and denaturation of proteins.

Cell Penetrating Peptide for Delivery of DNA
... Delivery of DNA, siRNA and drugs into cells is hampered by inefficient penetration across the plasma membrane. We describe a novel cell penetrating peptide (POD) capable of being chemically or electrostatically conjugated to small and/or large molecules and ferry those molecules into the cytoplasm o ...

Stopping nerve cell over-activity: a new drug target
... NMDA receptors from working could be a useful drug treatment for Parkinson’s that might stop nerve cell over-activity. But recent research has shown that the dopamineproducing cells affected in Parkinson’s have NMDA receptors that are different from ones found in other parts of the brain. And some t ...

Subventricular zone
The subventricular zone (SVZ) is a paired brain structure situated throughout the lateral walls of the lateral ventricles. It is composed of four distinct layers of variable thickness and cell density, as well as cellular composition. Along with the dentate gyrus of the hippocampus, the SVZ is one of two places where neurogenesis has been found to occur in the adult mammalian brain.
