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.

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,...

Antidepressant Drugs: Overview

Antidepressant Drugs: Overview

Antidepressant drugs are a class of medications primarily used for treating various mood disorders, including major depression, anxiety disorders, and other related conditions. These medicines work by modulating the neurotransmitter balance within the brain, alleviating depressive symptoms. Antidepressants can be broadly categorized into several groups according to their mechanism of action and chemical structure: Selective Serotonin Reuptake Inhibitors (SSRIs), Serotonin-Norepinephrine...

Antidepressant Drugs: MAOIs and Other Agents

Antidepressant Drugs: MAOIs and Other Agents

Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...

Human Genetics

Human Genetics

Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

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...

Neuroscience
Molecular Biology
Genetics

Background:

Serotonin (5-HT) is crucial for neural network development and function, modulating key processes like differentiation and synaptic plasticity.
Variability in serotonin gene expression, particularly the 5-HT transporter, is linked to temperament and psychopathological conditions such as anxiety and depression.

Purpose of the Study:

To investigate the role of serotonergic gene transcription in neuronal development and synaptic plasticity.
To identify gene-related molecular factors underlying brain disorders and to develop improved antidepressant treatments.

Main Methods:

Exploration of gene targeting strategies and gene transfer techniques using viral vectors.
Application of neuron-selective transcriptional control systems for investigating brain function.

Main Results:

Evidence suggests genetically determined variability in serotonergic gene expression influences temperamental traits.
Gene transfer techniques show potential for treating complex brain disorders.

Conclusions:

The serotonin system remains a key target for pharmaceutical development.
Novel strategies modifying serotonin function at the gene expression level offer promising alternative therapeutic approaches for brain disorders.
