Nature
|April 30, 1981
Resumen
Las células de neuroblastoma que se someten a diferenciación muestran cambios en las moléculas de la superficie celular. Los sitios de unión de la concanavalina A se inmovilizan, lo que sugiere un vínculo con la red de actina interna durante el desarrollo neuronal.
Área de la Ciencia:
- La neurociencia es la neurociencia.
- Biología celular Biología celular.
- La bioquímica es la bioquímica.
Sus antecedentes:
- Las células del neuroblastoma son modelos valiosos para estudiar el desarrollo neuronal.
- Los compuestos químicos como el DMSO y el dibutiril AMP cíclico inducen la diferenciación en estas células.
- La diferenciación implica extender los procesos, desarrollar la excitabilidad y formar sinapsis.
Objetivo del estudio:
- Para investigar la movilidad lateral de los componentes de la superficie celular durante la diferenciación del neuroblastoma.
- Comprender cómo cambian los componentes de la superficie celular durante el proceso de desarrollo neuronal.
Principales métodos:
- Utilizó la técnica de recuperación de foto blanqueamiento por fluorescencia.
- Se estudiaron células N1E-115 de neuroblastoma clonado.

01:19Ligand-gated Ion Channels
Ligand-gated ion channels are transmembrane proteins with a channel for ions to pass through and a binding site for a ligand. The channel opens only when a ligand attaches to the binding site.
Three Subfamilies of Ligand-gated Ion Channels
Ligand-gated ion channels fall into three subfamilies. The 'Cys-loop' includes the nicotinic acetylcholine receptors, γ-aminobutyric acid (GABA), glycine, and 5-hydroxytryptamine receptors. The second one is the 'Pore-loop' channels that include the...

01:35Cancer Cell Migration through Invadopodia
Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However, invadopodia can...
01:31Immunoglobulin-like Cell Adhesion Molecules
Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...

01:30Ligand-Gated Ion Channel Receptor: Gating Mechanism
Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...
01:15Neurogenesis and Regeneration of Nervous Tissue
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...
01:28Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists
Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy. SP binds and activates these...
