Neuron of stem cell types that have the capacity to differentiate into neurons. A report in "Nature" suggested that researchers had found a way to transform human skin cells into working nerve cells using a process called transdifferentiation in which "cells are forced to adopt new identities". It is often possible for peripheral axons to regrow if they are severed, but a neuron cannot be functionally replaced by one of another type (Llinás' law). Neuron A neuron, also known as a neurone (British spelling) and nerve cell, is an electrically excitable cell that receives, processes, and transmits information through electrical and
Nanoparticles for drug delivery to the brain drug. Bolaamphiphile nano-vesicles can cross the BBB, and they allow controlled release of the drug to target sites. Lipoplexes can also be formed from cationic liposomes and DNA solutions, to yield transfection agents. Cationic liposomes cross the BBB through adsorption mediated endocytosis followed by internalization in the endosomes of the endothelial cells. By transfection of endothelial cells through the use of lipoplexes, physical alterations in the cells could be made. These physical changes could potentially improve how some nanoparticle drug-carriers cross the BBB. Metal nanoparticles are promising as carriers for drug delivery to the brain. Common metals used for nanoparticle
