Microglial Cell Line (SIM-A9)
Microglial cell line (SIM-A9) expresses macrophage/microglia specific proteins, CD68 and Iba1.
Highlights:
- Cells express macrophage/microglia-specific proteins, CD68 and Iba1
- Responsive to exogenous inflammatory stimulation with lipopolysaccharide and ß-amyloid, triggering tyrosine kinase-mediated NFkB signaling cascades and TNFa secretion
- Exhibit phagocytic uptake of fluorescent labeled ß-amyloid and bacterial bioparticles
- Cells can be induced to pro- or anti-inflammatory M1/M2 microglial phenotypes
- Model system for microglial behavior in vitro
Microglia cells share functional similarities with macrophages, and are thought to act as the primary immune cells of the central nervous system (CNS). They monitor their microenviornment and become activated upon detection of abnormal and/or offensive signals. Activated microglia have been found in inflammatory conditions such as brain/spinal cord injury, ischemic strokes, infections and neurodegenerative diseases. Recent findings indicate that microglia are also involved in learning and memory by regulating synaptic plasticity.

Photomicrographs of SIM-A9 Cells
SIM-A9 cells expressing microglia/macrophage-specific proteins. SIM-A9 cells were treated without (Control; left panels) or with 2.5 ng/mL LPS(LPS; right panels) for 24 h prior to immunostaining for microglial markers, CD68 or Iba1, as well as for astrocyte and neuronal marker proteins, GFAP and MAP2, respectively. Scale bar = 50um.
