GFAP Astrocyte Marker | PanoBrain Glossary

Definition

Glial fibrillary acidic protein, an intermediate filament expressed by astrocytes and used as an immunofluorescence marker to identify reactive gliosis, astrocyte morphology, and glial spatial distributions relative to lesion sites.

Activation Reporter

GFAP upregulation indicates reactive astrogliosis

Spatial Analysis

Distribution relative to pathology reveals tissue response

Neuroinflammation Assessment

GFAP expression increases dramatically in reactive astrocytes surrounding injury, infection, or neurodegeneration. In a PanoBrain + StrataQuest workflow:

PanoBrain scans multi-channel fluorescence (DAPI + GFAP + additional markers)
StrataQuest classifies GFAP-positive cells and measures their spatial distribution
Distance maps reveal how astrocyte activation varies with proximity to lesion sites
Atlas registration enables region-specific comparison of gliosis across treatment groups
