The presence of vesicular glutamate transporters and vesicular monoamine transporters in the same neurons suggests that
A) cells that contain a lot of glutamate must store it in multiple types of vesicles.
B) glutamate can be co-released as a neurotransmitter along with dopamine or serotonin.
C) vesicular transporters are not selective.
D) gene expression has malfunctioned in these neurons.

Question

Quizplus · Accepted Answer

The presence of both vesicular glutamate transporters and vesicular monoamine transporters in the same neurons suggests that glutamate can be co-released as a neurotransmitter along with dopamine or serotonin. This phenomenon is known as co-transmission and is becoming increasingly recognized as an important mode of neurotransmission in the nervous system. Co-transmission allows for more complex and dynamic communication between neurons and can have important implications for behavior and disease states.
