ABSTRACT
There are three types of glial cells in(for short): sheath glia, socket glia and glutamate receptor glia. They are mainly located in four sensory organs including the amphid, the cephalic organ, the outer labial sensilla and the inner labial sensilla.glial cells play key roles in dendrite extension, neurite guidance and extension, and are essential for synaptogenesis and maintain the normal morphology and the function of sensory nerve endings as well. A recent study shown that some nematode neurons are derived from the glial cells. Moreover, nematodes glial cells can directly modulate the function of sensory neurons. Some glial cells can also respond to certain external stimuli, such as mechanical stimulation, and adjust the accompanying neuronal activities.The article summarizes the progress on effects of nematodes glial cells on the nervous system development and function.
