The TMEM119 antibody is a valuable tool for identifying and studying microglia, the resident immune cells of the central nervous system (CNS). TMEM119 (Transmembrane Protein 119) is a cell surface protein predominantly expressed in homeostatic microglia, distinguishing them from peripheral macrophages and other CNS-associated immune cells. Discovered through transcriptomic profiling, TMEM119 emerged as a specific microglial marker around 2014. addressing the limitations of traditional markers like Iba1 or CD68. which lack exclusivity to microglia. Its expression is largely restricted to the CNS under normal conditions, making it a reliable target for investigating microglial behavior in health and disease.
Researchers use TMEM119 antibodies in immunohistochemistry, flow cytometry, and immunofluorescence to visualize microglial distribution, activation states, and interactions in neurological disorders such as Alzheimer’s disease, multiple sclerosis, and neuroinflammation. Studies highlight its role in distinguishing resident microglia from infiltrating macrophages in injury or disease models, critical for understanding disease mechanisms. However, TMEM119 expression may downregulate during microglial activation or pathological states, requiring complementary markers for comprehensive analysis.
Despite its specificity, cross-reactivity variations across species (e.g., human vs. mouse) and unclear functional roles of TMEM119 itself warrant cautious interpretation. Ongoing research aims to elucidate its biological functions and refine its utility in translational neuroimmunology. Overall, TMEM119 antibodies have become indispensable for advancing microglia-focused research with implications for therapeutic development.
