In the relentless pursuit of scientific knowledge, cell culture models stand as indispensable tools that illuminate the intricate world of cellular behaviors, thereby laying the foundation for groundbreaking discoveries. Within this realm, microglia, the primary immune cells of the central nervous system (CNS), hold a unique and critical position. Functioning as the resident macrophages of the CNS, microglia are tasked with the vital role of maintaining tissue homeostasis by diligently phagocytosing misfolded proteins and cellular debris. The dysregulation of microglial function has emerged as a key contributor to the development of neurodegenerative diseases, including the formidable Alzheimer’s disease (AD). This has sparked a fervent exploration of microglia-targeted interventions and treatments, spanning preclinical studies involving cells and animals to human clinical trials.

In this study, we embark on an extensive journey into the world of human microglia, encompassing their unique cell culturing methods, their responses to small molecule treatments, and the intriguing realm of mRNA expression levels for microglia-specific markers. Our aim is to provide a rich resource for researchers eager to unravel the complexities of human microglia biology, potentially opening doors to novel insights and therapeutic strategies in the realm of neurodegenerative diseases.
