Glial fibrillary acidic protein (GFAP) is an intermediate filament protein expressed in astrocytes and neural stem cells. The GFAP gene is alternatively spliced, and expression of GFAP is highly regulated during development, on brain damage, and in neurodegenerative diseases. GFAPα is the canonical splice variant and is expressed in all GFAP-positive cells. In the human brain, the alternatively...

PURPOSE To determine the roles of glial fibrillary acidic protein (GFAP) and vimentin in Müller cell reactivity. METHODS Retinal detachments were created in mice deficient for GFAP and vimentin (GFAP(-/-)vim(-/-)) and age-matched wild-type (wt) mice. The reactivity of the retina was studied by immunofluorescence and electron microscopy. RESULTS Müller cell morphology was different and gluta...

Glial fibrillar) acidic protein (GFAP) is a constituent of intermediate filaments of glial cells of the astrocyte lineage. \Vecloncd a human GFAP complementary DINA,deduced the amino acid sequence, and established the chromosomal location (17q21) of the GFAP gene by Southern blot hybridization of somatic cell hybrids and by in situ hybridization. The authenticity of the complementary DNA was pr...

We have previously demonstrated that glial fibrillary acidic protein (GFAP) containing intermediate filaments in retinal Müller cells undergo both quantitative induction and subcellular reorganization as a response to long-term retinal detachment (an induced CNS degeneration wherein the Müller cells form a multicellular scar). This study demonstrates by RNA blotting analysis that normal retina ...

BACKGROUND Neurofilament light (NFL) and Glial Fibrillary Acidic Protein (GFAP) are integral parts of the axonal and astrocytal cytoskeletons respectively and are released into the cerebrospinal fluid (CSF) in cases of cellular damage. In order to interpret the levels of these biomarkers in disease states, knowledge on normal levels in the healthy is required. Another biomarker for neurodegener...

In the rat hippocampus and cortex, the transcription of glial fibrillary acidic protein (GFAP), an astrocyte intermediate filament protein, is inhibited by glucocorticoids. The present study examined the regulation of GFAP expression by glucocorticoids in astrocytes in vitro. Corticosterone (CORT) increased GFAP messenger RNA, protein, and transcription rates in cultured primary neonatal astroc...

objective(s): the muller cell is the principal glial cell of the vertebrate retina. the expression of glial fibrillary acidic protein (gfap) in the muller cells was used as a cellular marker for retinal damage. this study was done to evaluate the effect of gestational diabetes on retinal muller cells in rat's offspring. materials and methods: in this experimental study, 12 wistar rat dams ...

In the present study, the effects of chronic ethanol (ETOH) treatment on the glial fibrillary acidic protein (GFAP) immunoreactivity was investigated in adult rat brains. ETOH were administered as increasing concentrations of 2.4%-7.2% (v/v) gradually for 21 days. Immunocytochemistry revealed that chronic-ETOH treatment increased synthesis of GFAP. The increase in the diameter and the number of...
