Nöron uzantılarını teşvik etmek için makrofaj şartlandırılmış bir ortam kullanma

Executive Industry Relevance

This method enables mechanistic de-risking of neuroimmune interactions by quantifying macrophage-derived soluble factors that drive neurite outgrowth, supporting target validation in neurodegenerative disease models. The assay provides a disease-relevant system for evaluating immunomodulatory compounds with potential to enhance neuronal repair, informing early go/no-go decisions in discovery pipelines. By linking immune activation to functional neuronal phenotypes, it improves predictive confidence in lead identification stages.
