: Studies have suggested promising evidence that glial fibrillary acidic protein (GFAP) could be used as a blood biomarker to distinguish between ischemic stroke (IS) and intracerebral hemorrhage (ICH) in acute stage.: To determine the available evidence for GFAP as a blood biomarker for differentiating ICH from IS and stroke mimics using a meta-analysis approach.: Search terms were used for literature search: ("STROKE" [Mesh] OR "BIOMARKER" [Title/Abstract] OR "GFAP" [Title/Abstract])] OR "SPECIFICITY" OR "SENSTIVITY" at various search engines like PubMed, Google scholar, Trip database, clinicaltrial.gov for articles from 1990 through April 2019 using filter 'human subjects'. Data were analysed using software STATA version 13.: A pooled analysis including 12 studies suggested that GFAP if used as a biomarker to differentiate between different types of strokes (ICH from IS and mimics) had a sensitivity of 78% (95%
67% to 86%) and a specificity of 95% (95%
88% to 98%). Positive likelihood ratio (LR) was 14.4 and negative LR was 0.23. SROC with prediction and confidence contours suggests promising area under the curve 0.93, 95% CI ranges from 0.90 to 0.95. Diagnostic odds ratio with 95% CI was observed 63 (31 to 125).: Our meta-analysis suggests that GFAP has a promising diagnostic accuracy for the differentiation of ICH from IS and mimics. Further, phase II and phase III diagnostic test studies are required to validate the findings before using GFAP as a blood based biomarker for clinical use. This study was registered in OSF registries 10.17605/OSF.IO/B9JP4.

We investigated the role of serum Glial Fibrillary Acidic Protein (GFAP) and Ubiquitin C-Terminal Hydrolase-L1 (UCH-L1) in diagnosis of sepsis-associated encephalopathy(SAE), predicting prognosis and ...
Glial fibrillary acidic protein (GFAP), a type III intermediate filament, is a marker of mature astrocytes. The expression of GFAP gene is regulated by many transcription factors (TFs), mainly Janus k...
We performed fluorescent in situ hybridisation for loach Misgurnus anguillicaudatus bmi1, msi1 and sox2 genes, which are used as an indicator of the sites of multipotent stem cells. proliferating cell...
The volume and location of intracranial hematomas are well-known prognostic factors for traumatic brain injury (TBI). The aim of this study was to determine the relationship of serum biomarkers S100β...
Lipoprotein-associated phospholipase A2 (Lp-PLA2) is reflective of vascular inflammation and plays a role in the pathophysiology of cerebrovascular disease. We determine usefulness of serum Lp-PLA2 as...
Assessment of serum level of glial fibrillary acidic protein (GFAP) before surgery (on the day of surgery), 24 hours after surgery and on 3 or 4 postoperative day. Neuropsychological testi...
The aim of the study is to estimate the diagnostic accuracy of a combined biomarker test (including NMDA-Receptor fragments [NR2-peptide] and Glial fibrillary acidic protein) used to diffe...
The primary objective of the clinical trial is to evaluate the effect of time on levels of Ubiquitin C-terminal Hydrolase-L1 (UCH-L1) and Glial Fibrillary Acidic Protein (GFAP) biomarker l...
In this single center prospective cohort study a total of 100 patients scheduled for elective off-pump CABG will be recruited. They will be allocated to one study and one control group acc...

An intermediate filament protein found only in glial cells or cells of glial origin. MW 51,000.
A rare inherited disorder of myelin formation. Alexander disease is a progressive leukoencephalopathy whose hallmark is the widespread accumulation of cytoplasmic inclusions called Rosenthal fibers. The fibers contain GLIAL FIBRILLARY ACIDIC PROTEIN in association with ALPHA-CRYSTALLIN B CHAIN. Rosenthal fibers are found predominantly in ASTROCYTES located in the subependymal, subpial, and periventricular areas of the BRAIN.
Filaments 7-11 nm in diameter found in the cytoplasm of all cells. Many specific proteins belong to this group, e.g., desmin, vimentin, prekeratin, decamin, skeletin, neurofilin, neurofilament protein, and glial fibrillary acid protein.
A calcium-binding protein that is 92 AA long, contains 2 EF-hand domains, and is concentrated mainly in GLIAL CELLS. Elevation of S100B levels in brain tissue correlates with a role in neurological disorders.
A family of GLYCOSYLPHOSPHATIDYLINOSITOL-anchored cell surface receptors that are specific for GLIAL CELL LINE-DERIVED NEUROTROPHIC FACTORS. They form a multi-component receptor complex with PROTO-ONCOGENE PROTEIN C-RET and regulate a variety of intracellular SIGNAL TRANSDUCTION PATHWAYS in conjunction with c-ret protein.
