124 Part II Biology of the Cell Receptor Proteins and Signaling between Cells Communication between cells is com-mon in nature. Cell signaling occursin all multicellular organisms, provid-ing an indispensable mechanism forcells to influence one another.
In the normal communication process, dopamine is released by a neuron into the synapse (the small gap between two neurons), where it binds to specialized proteins called dopamine receptors on the neighboring neuron. By this process, dopamine acts as a chemical messenger, carrying a signal from neuron to neuron. Drugs of abuse can interfere with this normal communication process. For example, cocaine acts by binding to the dopamine transporter, blocking the removal of dopamine from the synapse.
