LPS-Induced Neuroinflammation Models

Assess Activated Microglial Cells, Astrocytes And More

Inflammation 1.jpg
 LPS-Induced Neuroinflammation
In the CNS, glia cells provide support to neural function and respond to stress and insults by upregulating inflammatory processes. Under normal conditions, these responses are kept in-check by anti-inflamamtory and neuroprotective mechanisms. However, in a diseased brain the dysregulation of glial cells promotes neuroinflammation that can lead to degeneration of neurons. Astrocytes react to injury by hypertrophy and upregulation of the glial-fibrillary acidic protein. 
LPS-induced Acute Neuroinflammation Model
Our LPS-induced acute neuroinflammation model provides a quick assessment of the number of activated microglia and astrocytes in the hippocampus. Following induction with LPS, brains are removed for histological assessment of the neuroimmunoreactive cells using the following markers:  
  • F4/80 for microglia cells (see graph below)
  • Glial-Fibrillary Acidic Protein (GFAP) IHC for astrocyte demonstration
