The expanded endings of their processes are known as end-feet, which act to induce and maintain the blood-brain barrier, and they express glutamate transporters.
A group led by Steinhauser found that there may be a second type of these cells, which express voltage-gated conductances, along with the usual gap- junction coupled type with a linear-voltage relationship. Their signaling has been shown to be evoked by activity in the Schaffer collateral pathway. These cells, which include Mtiller cells and Bergmann cells, act to buffer potassium ions from the extracellular space, and are colored blue by a Holzer stain. The expanded endings of their processes are known as end-feet, which act to induce and maintain the blood-brain barrier, and they express glutamate transporters. FTP, name these ►glial cells of the central nervous system, whose processes give them their star-like shape.
