What does GFAB mean in BIOLOGY
GFAB stands for Glial Fibrillary Acidic Protein. It is a type of intermediate filament protein that is expressed in astrocytes, which are the most common type of glial cell in the central nervous system. GFAB is a key component of the astrocyte cytoskeleton and plays an important role in maintaining the structural integrity of the brain. It is also involved in a variety of other cellular processes, including cell migration, proliferation, and differentiation.

GFAB: An Introduction to Glial Fibrillary Acidic Protein
GFAB: Functions and Significance
- Structural support: GFAB provides structural support to astrocytes and helps to maintain the integrity of the blood-brain barrier.
- Cell migration: GFAB is involved in the migration of astrocytes during development and after injury.
- Proliferation: GFAB is expressed in proliferating astrocytes and may play a role in regulating cell growth.
- Differentiation: GFAB is expressed in mature astrocytes and is required for their differentiation.
- Scar formation: GFAB is upregulated in astrocytes after injury and is a major component of the glial scar that forms in response to damage.
GFAB: Clinical Significance
GFAB is a useful marker for astrocytes in both normal and pathological conditions. It is used in the diagnosis of astrocytomas, which are tumors of astrocytes. GFAB is also used to study the response of astrocytes to injury and disease.

Essential Questions and Answers on Glial Fibrillary Acidic Protein in "SCIENCE»BIOLOGY"
What is GFAP?
GFAP (Glial Fibrillary Acidic Protein) is an intermediate filament protein primarily expressed in mature astrocytes, a type of glial cell that plays a crucial role in the central nervous system.
What is the function of GFAP?
GFAP provides structural support to astrocytes, maintaining the integrity of the astrocyte network and extracellular matrix. It also plays a role in astrocyte activation and reactivity, contributing to the formation of the glial scar in response to injury or disease.
Where is GFAP expressed?
GFAP is predominantly expressed in astrocytes throughout the central nervous system, including the brain and spinal cord. Its expression can be upregulated in response to injury, disease, or stress, indicating astrocyte activation.
What is the clinical significance of GFAP?
GFAP serves as a biomarker for astrocyte activation and is commonly used in neuropathology to identify areas of astrogliosis, a pathological condition characterized by an increase in astrocyte number and reactivity. Elevated GFAP levels can be associated with various neurological disorders, including brain injury, neurodegenerative diseases, and multiple sclerosis.
How is GFAP measured?
GFAP can be measured using various techniques, including immunohistochemistry, Western blotting, and enzyme-linked immunosorbent assays (ELISAs). Immunohistochemistry allows for the visualization of GFAP expression in tissue sections, while Western blotting and ELISAs provide quantitative measurements of GFAP levels in protein extracts.
