adenylate cyclase-inhibiting serotonin receptor signaling pathway

Definition

Target type: biologicalprocess

An adenylate cyclase-inhibiting G protein-coupled receptor signaling pathway initiated by serotonin binding to its receptor, and ending with the regulation of a downstream cellular process. [GOC:dph, GOC:mah, GOC:signaling, GOC:tb]

The adenylate cyclase-inhibiting serotonin receptor signaling pathway plays a crucial role in regulating various physiological processes, including mood, sleep, appetite, and cognition. This pathway is initiated by the binding of serotonin (5-HT) to specific G protein-coupled receptors (GPCRs), known as serotonin receptors. There are several serotonin receptor subtypes involved, but the most relevant for this pathway are the 5-HT1A and 5-HT1B receptors. Upon serotonin binding, these receptors activate a signaling cascade that ultimately leads to the inhibition of adenylate cyclase, an enzyme responsible for the production of cyclic adenosine monophosphate (cAMP). The inhibition of adenylate cyclase reduces cAMP levels, which in turn affects the activity of various downstream signaling pathways and target proteins.

Here's a detailed description of the pathway:

1. **Serotonin Binding:** Serotonin, a neurotransmitter synthesized in the brain, binds to the 5-HT1A or 5-HT1B receptor.

2. **G Protein Activation:** This binding event triggers a conformational change in the receptor, activating a heterotrimeric G protein associated with the receptor. The G protein consists of three subunits: alpha, beta, and gamma.

3. **Adenylate Cyclase Inhibition:** The activated alpha subunit of the G protein, specifically the Gαi subtype, binds to and inhibits adenylate cyclase. This inhibition prevents the conversion of ATP to cAMP.

4. **cAMP Reduction:** The inhibition of adenylate cyclase leads to a decrease in cAMP levels within the cell.

5. **Downstream Signaling Effects:** The reduction in cAMP levels has various downstream effects, including:
* **Reduced Protein Kinase A Activity:** cAMP is an activator of protein kinase A (PKA), so decreased cAMP levels lead to a decrease in PKA activity.
* **Altered Gene Expression:** PKA regulates the transcription of various genes, so changes in PKA activity affect gene expression patterns.
* **Modulation of Ion Channel Activity:** cAMP can influence the activity of certain ion channels, affecting cellular excitability.

6. **Physiological Consequences:** The net effect of this pathway is a reduction in neuronal activity and the modulation of various physiological processes, including:
* **Mood Regulation:** 5-HT1A receptors are implicated in mood regulation, and their activation via this pathway contributes to feelings of calmness and relaxation.
* **Sleep Regulation:** 5-HT1A receptors play a role in sleep-wake cycles.
* **Appetite Control:** 5-HT1B receptors are involved in regulating appetite and food intake.
* **Cognitive Function:** 5-HT1A receptors are involved in various cognitive processes, such as attention, memory, and learning.

The adenylate cyclase-inhibiting serotonin receptor signaling pathway is a complex and highly regulated system that plays a critical role in maintaining normal physiological function. Disruptions in this pathway can contribute to various disorders, including anxiety, depression, and eating disorders. Understanding this pathway is crucial for developing therapeutic strategies for treating these conditions.'

clozapineclozapine : A benzodiazepine that is 5H-dibenzo[b,e][1,4]diazepine substituted by a chloro group at position 8 and a 4-methylpiperazin-1-yl group at position 11. It is a second generation antipsychotic used in the treatment of psychiatric disorders like schizophrenia.

Clozapine: A tricylic dibenzodiazepine, classified as an atypical antipsychotic agent. It binds several types of central nervous system receptors, and displays a unique pharmacological profile. Clozapine is a serotonin antagonist, with strong binding to 5-HT 2A/2C receptor subtype. It also displays strong affinity to several dopaminergic receptors, but shows only weak antagonism at the dopamine D2 receptor, a receptor commonly thought to modulate neuroleptic activity. Agranulocytosis is a major adverse effect associated with administration of this agent.

olanzapineolanzapine : A benzodiazepine that is 10H-thieno[2,3-b][1,5]benzodiazepine substituted by a methyl group at position 2 and a 4-methylpiperazin-1-yl group at position 4.

Olanzapine: A benzodiazepine derivative that binds SEROTONIN RECEPTORS; MUSCARINIC RECEPTORS; HISTAMINE H1 RECEPTORS; ADRENERGIC ALPHA-1 RECEPTORS; and DOPAMINE RECEPTORS. It is an antipsychotic agent used in the treatment of SCHIZOPHRENIA; BIPOLAR DISORDER; and MAJOR DEPRESSIVE DISORDER; it may also reduce nausea and vomiting in patients undergoing chemotherapy.
