Dorsal root ganglion nerve cells stained to reveal

the microtubules (green) and actin filaments

(red). The axon shaft contains bundles of

microtubules that give structural support and

carry cargo (protein and membranes) to and from

the cell body. The "hand-like" structure at the end

of the axon is called the growth cone. This is

very motile and reads and integrates molecular

cues in the environment. It also guides the

growing nerve to its target in the growing embryo.

Above, time-lapse images of second-generation model-cell division. The initial division was followed by budding of one of the daughter cells. The small bud contains a newly-formed dextran-rich aqueous phase coated by the red membrane domain, while the larger body of the model cell contains the PEG-rich aqueous phase coated by the green membrane domain.

Excitotoxicity – Medical Illustration

Excitotoxicity is the pathological process by which nerve cells are damaged and killed by excessive stimulation by neurotransmitters such as glutamate and similar substances. This occurs when receptors for the excitatory neurotransmitter glutamate are overactivated. Pathologically high levels of glutamate can cause excitotoxicity by allowing high levels of calcium ions to enter the cell. Calcium influx into cells activates a number of enzymes. These enzymes go on to damage cell structures such as components of the cytoskeleton, membrane, and DNA.
