Summary
Rett syndrome, a neurological disorder from MECP2 gene mutations, involves altered biogenic amine metabolism. Targeting this pathway offers a promising strategy for improving patient quality of life.
Area of Science:
- Neuroscience
- Genetics
- Biochemistry
Background:
- Rett syndrome (RTT) is a severe neurological disorder linked to MECP2 gene mutations.
- While brain structure is often normal, RTT patients exhibit deficits in bioaminergic metabolism.
- Transgenic mouse models with Mecp2 defects confirm a link between MECP2 function and biogenic amine metabolism.
Purpose of the Study:
- To review human and mouse data on biogenic amine metabolism in Rett syndrome.
- To explore the role of biogenic amines in RTT pathophysiology.
- To present potential pharmacological treatments targeting biogenic amine deficits.
Main Methods:
- Review of existing human and mouse studies on MECP2 and biogenic amines.
- Analysis of the role of biogenic amines in RTT-affected functions.
- Evaluation of current knowledge for developing therapeutic strategies.
Main Results:
- Biogenic amines are repeatedly found to be altered in RTT patients.
- Biogenic amines significantly influence autonomic and cognitive functions, many of which are affected in RTT.
- Deficits in bioaminergic metabolism are identified at cellular and molecular levels in RTT.
Conclusions:
- Biogenic amines play a crucial role in Rett syndrome pathophysiology.
- Modulating biogenic amine metabolism is a promising therapeutic strategy for RTT.
- Targeting biogenic amine metabolism may improve the quality of life for RTT patients.

01:21Smooth Endoplasmic Reticulum
Smooth endoplasmic reticulum or smooth ER is a sub-organelle with specialized functions in animal cells and plant cells. It is often associated with the tubule morphology of the endoplasmic reticulum.
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...

01:13Functional Brain Systems: Reticular Formation
The reticular formation is a complex network of gray and white matter located within the brainstem extending from the medulla to the midbrain.
Within the reticular formation, there are several distinct nuclei that can be classified into three broad categories. The Raphe nuclei are located along the midline of the brainstem. They are primarily known for their role in synthesizing and releasing serotonin, a neurotransmitter involved in regulating mood, appetite, sleep, and circadian rhythms. The...

01:26Physical Properties of Amines
Amines with low molecular weight are usually gaseous at room temperature, while those with high molecular weight are liquid or solids in nature. Usually, low molecular weight amines have a rotten fish-like smell. Diamines typically have a pungent smell. For instance, cadaverine and putrescine, depicted in Figure 1, are two molecules responsible for decaying tissue.
01:29Drugs Affecting Neurotransmitter Synthesis
Drugs affecting neurotransmitter synthesis can impact the adrenergic neuron and the synthesis of neurotransmitters. For example, α-methyltyrosine and carbidopa target specific enzymes involved in catecholamine synthesis. α-methyltyrosine inhibits the enzyme tyrosine hydroxylase, which converts tyrosine into dopamine. By blocking this enzyme, α-methyltyrosine reduces dopamine production and other catecholamines. Carbidopa, on the other hand, inhibits the enzyme dopa decarboxylase, which converts...
01:21Drugs Affecting Neurotransmitter Release or Uptake
Certain drugs can affect how neurotransmitters called catecholamines, are released or taken back up in the adrenergic neuron. They can have different effects on the body's sympathetic transmission. Reserpine, a natural compound found in the Rauwolfia shrub, blocks a transporter called vesicular monoamine transporter (VMAT), which leads to a buildup of catecholamines in the cell and reduces sympathetic transmission. Another drug called guanethidine works in multiple ways, including blocking...
01:27Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within the...
