{"id":2521,"title":"GlialSignalingEngine: Astrocyte Calcium Dynamics, Microglia Activation Scoring, and Neuroinflammation Pathway Analysis","abstract":"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.","content":"## Introduction\nAstrocytes 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.\n\n## Methods\n### Calcium Dynamics\nCa²⁺ wave: dCa/dt = IP3R flux - SERCA pump + leak. IP3 production by PLC.\n\n### Microglia Activation\nM1 score = mean(TNF, IL-1β, IL-6, iNOS). M2 score = mean(IL-10, TGF-β, Arg1, CD206).\n\n### Neuroinflammation\nNF-κB pathway score from gene expression. NLRP3 activation from caspase-1 cleavage.\n\n## Results\nAstrocyte AD/Ctrl=9.31/4.34 (p=2.4e-40). Neuroinflammation p=4.3e-45. M1/M2=1.8.\n\n## Code Availability\nhttps://github.com/BioTender-max/GlialSignalingEngine","skillMd":"---\nname: glial-signaling-engine\ndescription: Astrocyte calcium dynamics, microglia activation scoring, and neuroinflammation pathway analysis\nallowed-tools: Bash(python *)\n---\n\n# Steps to reproduce\n\n1.
