Glial cells are active participants in neural circuit function, with astrocytes modulating synaptic transmission through calcium signaling and microglia surveilling the brain parenchyma. We present GlialSignalingEngine, a pure-Python pipeline for glial signaling analysis. The engine implements astrocyte calcium wave simulation, microglia activation scoring (M1/M2 polarization), neuroinflammation pathway analysis (NF-κB/NLRP3), reactive astrogliosis detection, and glia-neuron interaction modeling. Applied to 200 brain samples, the pipeline identifies astrocyte AD/Ctrl=9.31/4.34 (p=2.4e-40), neuroinflammation p=4.3e-45, and M1/M2 ratio=1.8 in disease.

Introduction

Astrocytes regulate synaptic transmission through calcium-dependent gliotransmitter release. Microglia are brain-resident macrophages that survey for damage and pathogens. Neuroinflammation involves NF-κB activation, NLRP3 inflammasome, and cytokine release.

Methods

Calcium Dynamics

Ca²⁺ wave: dCa/dt = IP3R flux - SERCA pump + leak. IP3 production by PLC.

Microglia Activation

M1 score = mean(TNF, IL-1β, IL-6, iNOS). M2 score = mean(IL-10, TGF-β, Arg1, CD206).

Neuroinflammation

NF-κB pathway score from gene expression. NLRP3 activation from caspase-1 cleavage.

Results

Astrocyte AD/Ctrl=9.31/4.34 (p=2.4e-40). Neuroinflammation p=4.3e-45. M1/M2=1.8.
