Identity of neurotrophic molecules released from astroglia by vasoactive intestinal peptide

Abstract

Subnanomolar concentrations of VIP elicit a survival-producing action in CNS cultures composed of both astroglia and neurons. This neurotrophic action is mediated by a complex array of substances released by VIP from astrocytes. Included in this glial protein mixture is a cytokine (interleukin-1 alpha), a serine protease inhibitor (protease nexin I), and an extracellular stress protein (activity-dependent neurotrophic factor). In dissociated spinal cord cultures, all of these substances exhibit neuroprotection from neuronal cell death produced by electrical blockade with tetrodotoxin. All these substances produce neuronal cell death when test cultures are treated with neutralizing antisera to any one of them. They are all apparently necessary for the survival of a subpopulation of neurons that are dependent on spontaneous, excitatory neurotransmission. Our view is that these substances are components of a glia-derived environment that regulates, together with target-derived growth factors, the survival fate of developing neurons. In addition, it is our belief that some of these glia-derived substances will be found to have active roles in the injury response to the CNS or in the regulation of VIP-mediated growth in other tissue...Continue Reading

Astrocytes in Repair & Regeneration

Astrocytes are glial cells found within the CNS and are able to regenerate new neurons. They become activated during CNS injury and disease. The activation leads to the transcription of new genes and the repair and regeneration of neurons. Discover the latest research on astrocytes in repair and regeneration here.

Astrocytes & Neurodegeneration

Astrocytes are important for the health and function of the central nervous system. When these cells stop functioning properly, either through gain of function or loss of homeostatic controls, neurodegenerative diseases can occur. Here is the latest research on astrocytes and neurodegeneration.

Alzheimer's Disease: APP

Amyloid precursor protein (APP) proteolysis is critical for the development of Alzheimer's disease, a neurodegenerative disease associated with accumulation of amyloid plaques in the brain. Here is the latest research on APP and Alzheimer's disease.

Astrocytes

Astrocytes are glial cells that support the blood-brain barrier, facilitate neurotransmission, provide nutrients to neurons, and help repair damaged nervous tissues. Here is the latest research.

Astrocytes & Amyloid

Astrocytes are thought to play a role in amyloid production and have been implicated in neurodegenerative diseases such as Alzheimer’s disease. Here is the latest research on the relationship between astrocytes and amyloid.
