Neuroinflammation Sensitive Neurons is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
This page provides comprehensive information about the cell type. See the content below for detailed information.
Neuroinflammation-sensitive neurons are neuronal populations that are particularly vulnerable to the toxic effects of chronic neuroinflammation. These neurons undergo dysfunction and death when exposed to prolonged inflammatory microenvironments.
- TLRs (Toll-like receptors): Pattern recognition
- RAGE: Advanced glycation end products receptor
- NLRs: NOD-like receptors, inflammasome formation
- cGAS-STING: Cytosolic DNA sensing
- IL-1β: Primary neurotoxic cytokine
- IL-6: Acute phase response
- TNF-α: Potent neurotoxic effects
- IFN-γ: MHC upregulation, antigen presentation
- CXCL10: Chemokine attracting more immune cells
- Dopaminergic neurons
- Highly vulnerable to microglial activation
- NADPH oxidase produces ROS
- iNOS produces nitric oxide
- Oligodendrocytes
- Direct immune attack
- Demyelination
- Precursor cells also affected
- Motor neurons
- Astroglial inflammation
- Complement-mediated damage
- T-cell infiltration
- Microglial activation: Chronic or acute
- Astrocytic dysfunction: Loss of support functions
- Peripheral immune infiltration: Breach of BBB
- Neuronal inflammation: Neurons produce cytokines
- Synaptic stripping: Microglia remove synapses
- Excitotoxicity: GLT-1 downregulation
- Oxidative stress: iNOS, NADPH oxidase
- Energy failure: Mitochondrial dysfunction
- Apoptosis: Death receptor activation
- Microglia-neuron: Direct contact, cytokine signaling
- Astrocyte-neuron: Metabolic support loss
- Oligodendrocyte-neuron: Myelin maintenance
- Minocycline: Microglial inhibitor
- NSAIDs: COX-1/2 inhibition
- Natalizumab: BBB protection
- GLP-1 receptor agonists: Anti-inflammatory
- TREM2 agonists: Enhance phagocytosis
- CSF1R inhibitors: Reduce microglia
- CX3CR1 modulators: Fractalkine signaling
- IL-6, IL-1β, TNF-α in CSF
- Microglial PET imaging
- Neopterin levels
