Summary
Neuregulin 1 (NRG1) and its receptor erbB4 are implicated in schizophrenia. New research shows they regulate synaptic transmission in the brain, suggesting potential synaptic defects in the disorder.
Area of Science:
- Neuroscience
- Molecular Biology
- Genetics
Background:
- Genetic studies suggest Neuregulin 1 (NRG1) and its receptor erbB4 are linked to schizophrenia susceptibility.
- The precise roles of NRG1 and erbB4 in central nervous system (CNS) synaptic transmission and circuitry remain unclear.
Discussion:
- Recent studies demonstrate that NRG1 and erbB4 play a regulatory role in synaptic transmission.
- These findings specifically highlight the involvement of NRG1 and erbB4 at both glutamate and GABA synapses in the brain.
Key Insights:
- NRG1 and erbB4 modulate excitatory (glutamate) and inhibitory (GABA) neurotransmission in the brain.
- This regulation of synaptic function by NRG1 and erbB4 is a novel finding with implications for understanding brain circuitry.
Outlook:
- The identified roles of NRG1 and erbB4 in synaptic transmission open new avenues for investigating the pathophysiology of schizophrenia.
- These discoveries suggest that synaptic defects could be a contributing factor to schizophrenia development.

Integration of Synaptic Events
Synaptic integration mainly includes the summation of graded potentials. Graded potentials, regardless of their type, cause subtle alterations in membrane voltage, resulting in either depolarization or hyperpolarization. These incremental changes, when combined or summed, can propel the neuron toward its threshold. Consider, for example, a membrane experiencing a +15 mV shift, causing it to depolarize from -70 mV to -55 mV. In this scenario, graded potentials govern the membrane's ability to...
The Synapse
Neurons communicate with one another by passing on their electrical signals to other neurons. A synapse is the location where two neurons meet to exchange signals. At the synapse, the neuron that sends the signal is called the presynaptic cell, while the neuron that receives the message is called the postsynaptic cell. Note that most neurons can be both presynaptic and postsynaptic, as they both transmit and receive information.
Synaptic Signaling
Neurons communicate at synapses, or junctions, to excite or inhibit the activity of other neurons or target cells, such as muscles. Synapses may be chemical or electrical.
Most synapses are chemical, meaning an electrical impulse or action potential spurs the release of chemical messengers called neurotransmitters. The neuron sending the signal is called the presynaptic neuron, and the neuron receiving the signal is the postsynaptic neuron.

Ligand-Gated Ion Channel Receptor: Gating Mechanism
Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...
Excitatory and Inhibitory Effects of Neurotransmitters
When an action potential reaches the presynaptic axon terminal, it releases neurotransmitters from the neuron into the synaptic cleft at a chemical synapse. The released neurotransmitter can be excitatory or inhibitory. The critical criteria commonly used to determine whether a molecule is a neurotransmitter at a chemical synapse are the molecule's presence in the presynaptic neuron. Second, its release is in response to strong presynaptic depolarization. And lastly, the presence of specific...
