Roles of Satellite Cells in Sensory Ganglia

Abstract

Many hypotheses about the role of satellite cells have been proposed since their discovery. Among the suggested functions, the following are supported by fairly convincing evidence obtained in sensory ganglia:

• 1) Mechanical support for ganglionic neurons;

• 2) Control of the traffic of materials to and from the ganglionic neuron;

• 3) Control of the levels of neuroactive amino acids; and

• 4) “Trophic” role toward the ganglionic neurons.
