G-protein Coupled Receptors

G-protein Coupled Receptors

G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.

Biosynthesis of Nucleic Acids

Biosynthesis of Nucleic Acids

Nucleic acid biosynthesis is a fundamental biochemical process that produces the purine and pyrimidine nucleotides essential for DNA and RNA synthesis. This pathway maintains a balanced nucleotide pool, preventing imbalances that could jeopardize genetic integrity and cellular function. Given the crucial role of nucleotides, their synthesis is tightly regulated to ensure proper cellular homeostasis.Purine BiosynthesisThe biosynthesis of purine nucleotides begins with ribose-5-phosphate, a...

Neurotransmitters

Neurotransmitters

Neurotransmitters are essential chemical messengers within the nervous system, facilitating the communication between neurons. These chemical messengers, varying in function and effect, are critical for sustaining various aspects of neurological health and emotional well-being.

Depression: Overview

Depression: Overview

Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...

Bipolar Disorder

Bipolar Disorder

Bipolar disorder is a chronic mental health condition marked by significant mood fluctuations, including episodes of mania and depression. Elevated energy levels, heightened mood or irritability, impulsive behavior, reduced sleep needs, rapid speech, racing thoughts, inflated self-esteem, and distractibility characterize mania. Individuals with bipolar disorder often alternate between depressive and manic states, with periods of emotional stability lasting an average of six months to a year.

Depressive Disorders: Etiology

Depressive Disorders: Etiology

Depressive disorders result from a complex interplay of biological, psychological, and sociocultural factors, each contributing uniquely to the development and persistence of the condition. Understanding these factors provides critical insight into the multifaceted nature of depression.
Biological Factors in Depression
Biological predispositions significantly influence the risk of developing depressive disorders. Genetic studies highlight the role of variations in the serotonin transporter...

Background:

Purinergic system, involving uric acid and adenosine, influences mood, sleep, cognition, and impulsivity.
A century-old hypothesis links purinergic dysfunction to mood disorders.
Recent studies show elevated gout risk in bipolar disorder (BD) patients and benefits of purinergic modulators in mania.

Purpose of the Study:

To review the critical role of the purinergic system in the pathophysiology of mood disorders.
To highlight the purinergic system as a potential therapeutic target for mood disorders.

Main Methods:

Review of existing literature, including genetic studies, population-based research, and meta-analyses.
Discussion of neuroimaging techniques like brain spectroscopy and Positron Emission Tomography (PET) for studying the purinergic system.

Main Results:

Uric acid levels correlate with energy and activity in the BD spectrum.
Genetic studies implicate P1 and P2 receptor subtypes in mood disorders.
Purinergic modulators have demonstrated benefits in bipolar mania.

Conclusions:

The purinergic system is a key player in mood disorder pathophysiology.
Targeting the purinergic system offers potential for developing novel therapies with antidepressant, mood-stabilizing, and cognitive-enhancing effects.
