Autoimmune GFAP Astrocytopathy is an autoimmune disease in which the immune system of the patient attacks a protein of the nervous system called glial fibrillary acidic protein (GFAP). It was described in 2016 by researchers of the Mayo Clinic in the United States.
Glial fibrillary acidic protein (GFAP) is a protein that is encoded by the GFAP gene in humans. [5] It is a type III intermediate filament (IF) protein that is expressed by numerous cell types of the central nervous system (CNS), including astrocytes [6] and ependymal cells during development. [7]
They recognized these symptoms were the result of inflammation of the optic nerve and spinal cord, respectively. [74] [77] [78] In 2002, Mayo Clinic researchers identified a humoral mechanism, targeting a perivascular protein, as the culprit of NMO, [26] and in 2004 an unknown specific autoantibody was found.

A type of astrocyte with an aging-related pathology has been described over the last fifty years. Astrocytes of this subtype possess prominent cytoplasmic granules that are intensely stained by Gomori's chrome alum hematoxylin stain, and hence are termed Gomori-positive (GP) astrocytes.
Reactive astrogliosis is a spectrum of changes in astrocytes that occur in response to all forms of CNS injury and disease. Changes due to reactive astrogliosis vary with the severity of the CNS insult along a graduated continuum of progressive alterations in molecular expression, progressive cellular hypertrophy, proliferation and scar formation.
The Mayo Clinic diet, a program that adheres to this notion, was developed by medical professionals based on scientific research, so you can trust that this program is based on science, and not ...
The main role of astrocytes is to maintain brain homeostasis and neuronal metabolism. When the astrocytes become activated, they begin to respond to damage. [3] Astrocyte activation, known as astrogliosis, responds to neurological trauma, infections, degradations, epilepsy, and tumorigenesis. Each neurological insult plays a major role in ...
A new study explains how mitochondria act as “reservoirs” to store NAD for cells to use, which could help scientists come up with NAD-boosting therapies to combat aging and age-related diseases.
