Neuron Structure

Neuron Structure

Neurons are the main type of cell in the nervous system that generate and transmit electrochemical signals. They primarily communicate with each other using neurotransmitters at specific junctions called synapses. Neurons come in many shapes that often relate to their function, but most share three main structures: an axon and dendrites that extend out from a cell body.

Assembly of Complex Microtubule Structures

Assembly of Complex Microtubule Structures

Complex microtubule structures are present in resting cells and in dividing cells. In resting cells, they are responsible for maintaining the cellular architecture, tracks for intracellular transport, positioning of organelles, assembly of cilia and flagella. They mediate the bipolar spindle assembly for chromosomal segregation and positioning of the cell division plate in dividing cells. The formation of microtubule complex structures depends on the cell type, cell stage, and cell function.

Nervous Tissue: Glial Cells

Nervous Tissue: Glial Cells

Glia, or neuroglia, are vital support cells that assist neurons in their functions. The term "glia" originates from the Greek word for "glue," reflecting their role in holding the nervous system together. These cells can be categorized into six types: four in the central nervous system (CNS) and two in the peripheral nervous system (PNS).
The CNS glial cell includes the astrocytes, the oligodendrocytes, the microglia, and the ependymal cells.
Astrocytes are star-shaped glial cells that interact...

The Supercomplexes in the Crista Membrane

The Supercomplexes in the Crista Membrane

The mitochondrial cristae membrane is the primary site for the oxidative phosphorylation (OXPHOS) process of energy conversion mediated through respiratory complexes I to V. These complexes have been widely studied for decades, and it has been proven that they form supramolecular structures called respiratory supercomplexes (SC). These higher-order complexes may be crucial in maintaining the biochemical structure and improving the physiological activity of the individual complexes while...

Background:

Astrocyte morphology is crucial for central nervous system (CNS) function, characterized by its complex and dynamic nature.
It is influenced by molecular signals, cell-cell interactions, and physical environmental factors.
Astrocyte structure plays a vital role in synaptic plasticity and neurotransmission regulation.

Purpose of the Study:

To synthesize current knowledge on astrocyte morphogenesis at various levels, from molecular cues to anatomical context.

Literature review synthesizing current research on astrocyte morphology.
Discussion of molecular, cellular, and anatomical factors influencing astrocyte shape.
Overview of mathematical modeling techniques (graph theory, applied topology) for analyzing branching structures.
Exploration of computational tools, including deep learning, for morphological analysis.

Main Results:

Astrocyte structure is dynamically shaped by molecular cues, cell adhesion, and physical constraints.
Motile astrocyte leaflets contribute to synaptic plasticity by regulating neurotransmission.
Pathological changes in astrocyte morphology are linked to CNS dysfunction, affecting synaptic regulation, excitability, and metabolism.
