How can the glutamate induced down regulation of GABA B receptors be specific?
Homework Answers
Glutamate binds with glutamate receptors which down-regulates GABA B receptors by shifting the balance from recycling to lysosomal degradation. Sustained activation of glutamate receptors triggers lysosomal degradation of GABA B receptors, mediated by AMPA (α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid) receptors. The down-regulation also depends on Ca2+ Influx through L-type voltage-gated Ca2+ channels.

1) Which ligand-gated ion channels does (glutamate / GABA / glycine) open? 2) How do changes in (potassium / sodium) concentration affect the resting membrane potential? 3) If (sodium / potassium / chloride) channels are locked open, the membrane potential will continue to change due to ion flow until it reaches what value? (give a numerical value)

INFORMATION ABOUT IMAGE G FOR QUESTIONS 12-15:
GABAB receptors (GABABRs) are
G-protein-coupled receptors that can be found on both pre- and
postsynaptic neurons. When they are activated by GABA, they can
have a range of effects. For the synapse you are studying in the
following questions, the effects of GABABRs are
indicated in IMAGE G.
You are doing a series of experiments in which you are recording
from the pre- and postsynaptic cell at a synapse. The experiments
described below...

Part Uncle Mel suffers from depression and is having trouble sleeping. Some medications can increase the amount of neurotransmitter in the synapse by preventing its re-uptake into the presynaptic neuron or its degradation. This increases the level of the neurotransmitter in the synapse and prolongs its effects. Select which neurotransmitters you think might be a good target for anti-depressant drugs.
