A neuron, or nerve cell, consists of a cell body, short extensions called dendrites, and a long arm called an axon that branches off into axon terminals. For messages to be sent from one neuron to another, an electrical signal travels down the axon, and the axon terminals pass an electrochemical signal to the dendrites of other neurons.

Immunofluorescence image of breast cancer cells (MCF 7) treated with a MicroQuin therapeutic taken at 100x magnification. The staining of the cell shows a normal nucleus (blue) with the endoplasmic reticulum (green) localized of the cell showing significant vacuolation. This image shows a unique form of cell death, known as paraptosis, induced by MicroQuins therapeutics which offers a unique treatment for cancer.
