Summary
Gap junctions, formed by connexin proteins, are vital for brain communication and neurodevelopment. Understanding connexin roles in health and disease may lead to new neurological disorder therapies.
Area of Science:
- Neuroscience
- Cell Biology
Background:
- Gap junctions are crucial for intercellular communication in the central nervous system (CNS).
- These channels are formed by connexin proteins, with various types expressed in specific CNS cell types and developmental stages.
Purpose of the Study:
- To explore the roles of connexins, specifically Cx36 and Cx43, in neurodevelopment and CNS pathology.
- To investigate how connexin imbalances and mutations affect function in neurodevelopment and disease.
- To highlight the potential for developing targeted therapies for neurological disorders based on connexin function.
Main Methods:
- Review of existing literature on connexin expression and function in the CNS.
- Analysis of connexin roles in neurodevelopmental processes.
- Examination of connexin involvement in pathological CNS conditions.
Main Results:
- Neuronal Cx36 and glial Cx43 are critical for neurodevelopment.
- Connexin expression, trafficking, and mutations impact cell death in neurodevelopment and disease.
- Connexins mediate distinct aspects of the CNS response to pathological conditions.
Conclusions:
- Connexins are key players in both normal brain function and disease states.
- Therapeutic strategies targeting gap junctions hold promise for treating neurological disorders.

10.1K
The cytoplasm of adjacent animal cells can exchange small molecules, ions, and secondary messengers via the communication channels which form the gap junctions. These junctions comprise a few hundred to thousands of molecular channels, each made of two halves, called the connexon hemichannel. A connexon is a hexamer of six transmembrane connexin proteins, which assemble radially, thus forming a pore or channel in the center. One connexon hemichannel docks with a corresponding connexon on the...

Multicellular organisms employ a variety of ways for cells to communicate with each other. Gap junctions are specialized proteins that form pores between neighboring cells in animals, connecting the cytoplasm between the two, and allowing for the exchange of molecules and ions. They are found in a wide range of invertebrate and vertebrate species, mediate numerous functions including cell differentiation and development, and are associated with numerous human diseases, including cardiac and...

01:14Overview of Cell-Cell Junctions
31.1K
The complex three-dimensional arrangement of cells in any multicellular organism is defined and maintained by interactions of cells with each other and the extracellular matrix. Cell-cell junctions are specialized structures where the multi-protein complexes on one cell interact with the multi-protein complexes on another cell. These cell junctions are classified into three main types based on their function — occluding, anchoring, and gap junctions.

Electrical synapses found in all nervous systems play important and unique roles. In these synapses, the presynaptic and postsynaptic membranes are very close together (3.5 nm) and are actually physically connected by channel proteins forming gap junctions.
Gap junctions allow the current to pass directly from one cell to the next. In contrast, in the chemical synapse, the neurotransmitters carry the information through the synaptic cleft from one neuron to the next. They consist of two...

03:14Notch Signaling Pathway
6.8K
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...

01:19Contact-dependent Signaling
48.2K
Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.
