Summary
Rett syndrome (RS) involves synaptic dysfunction due to methyl-CpG-binding protein 2 (MeCP2) gene mutations. Research in mouse models reveals impaired synaptic transmission and plasticity, offering insights into neurological disorders.
Area of Science:
- Neuroscience
- Genetics
- Molecular Biology
Background:
- Synaptic connections are crucial for brain function and are often altered in neurological and psychiatric diseases.
- Synaptopathies are brain disorders characterized by impaired synaptic function and plasticity.
- Rett syndrome (RS) is an X-linked dominant neurological disorder frequently caused by mutations in the methyl-CpG-binding protein 2 (MeCP2) gene.
Purpose of the Study:
- To review current knowledge on synaptic alterations in mouse models of RS caused by MeCP2 mutations.
- To discuss potential experimental therapies for RS.
- To explore the neurobiological underpinnings of cognitive deficits in RS.
Main Methods:
- Review of experimental data from mouse models of RS.
- Analysis of studies investigating synaptic transmission and plasticity in the absence of functional MeCP2.
- Examination of research on therapeutic strategies for RS.
Main Results:
- Mutations in the MeCP2 gene lead to synaptic alterations in mouse models of RS.
- Impaired homeostasis of synaptic transmission occurs in specific brain regions in RS models.
- Several forms of experience-induced neuronal plasticity are compromised without functional MeCP2.
Conclusions:
- RS may result from impaired synaptic transmission homeostasis.
- Understanding MeCP2's role in synaptic function is key to addressing RS.
- This research advances the identification of neurobiological bases for human cognition and neurological disorders.

01:26Chemical Synapses
Chemical synapses are specialized sites between two neurons or between a neuron and a non-neuronal cell like a muscle, glandular or sensory cell.
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...

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...

01:33Pleiotropy
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...
01:11Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase
Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...
01:29Excitatory 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...
