Introduction

Neuroinflammation-responsive neurons are neurons that actively respond to inflammatory signals in the central nervous system. These cells play a critical role in neurodegeneration, as chronic neuroinflammation is a hallmark of Alzheimer's disease, Parkinson's disease, ALS, and other neurodegenerative disorders. Understanding neuronal responses to inflammation is crucial for developing therapeutic interventions[@glass2010].

Overview

Pro## Inflammatory Signals-inflammatory Cytokines

• IL-1β: Interleukin-1 beta — primary inflammatory mediator
• TNF-α: Tumor necrosis factor alpha — potent neurotoxicity
• IL-6: Interleukin-6 — acute phase response
• IFN-γ: Interferon gamma — modulates synaptic function

Overview

Pro## Inflammatory Signals-inflammatory Cytokines

• IL-1β: Interleukin-1 beta — primary inflammatory mediator
• TNF-α: Tumor necrosis factor alpha — potent neurotoxicity
• IL-6: Interleukin-6 — acute phase response
• IFN-γ: Interferon gamma — modulates synaptic function

Other Mediators

• Prostaglandins: COX-2 derived (PGE2)
• Complement components: C1q, C3
• Reactive oxygen species (ROS): Oxidative stress
• Nitric oxide (NO): Via iNOS induction

Neuronal Responses

1. Stress Response Pathways

• NF-κB activation: Pro-inflammatory gene transcription
• MAPK pathways: JNK, p38 signaling
• ER stress: Unfolded protein response
• Heat shock proteins: Cellular protection

2. Synaptic Dysfunction

• Synaptic pruning: Enhanced by complement
• LTPmechanisms/long-term-potentiation) impairment: Memory circuit disruption
• Neurotransmitter dysregulation: Excitotoxicity
• Dendritic spine loss: Structural changes

3. Metabolic Disturbances

• Mitochondrial dysfunction: Energy failure
• ATP depletion: Cellular stress
• Calcium dysregulation: Homeostasis disruption
• Autophagy impairment: Protein clearance issues

4. Cell Death Pathways

• Caspase activation: Apoptosis
• Necroptosis: Inflammatory cell death
• Ferroptosis: Iron-dependent cell death
• Axonal degeneration: Wallerian-like processes
