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 that it can bind and undergo endocytosis. Another mechanism is "adsorption mediated transcytosis", where electrostatic interactions are involved in mediating nanoparticle crossing of the BBB. Cationic nanoparticles (including cationic liposomes) are of interest for this mechanism, because their positive charges assist binding on the brain's endothelial cells. Using TAT-peptides, a cell-penetrating peptide, to functionalize the surface of cationic nanoparticles can further improve drug transport into the brain. In contrast to the above mechanisms, a delivery with magnetic fields doesn't strongly depend on the biochemistry of the brain. In this case, nanoparticles are literally pulled across the BBB via application of
