Macrophage Depletion Mouse Model Development Service

Macrophages, vital components of the mononuclear phagocyte system, serve pivotal functions in prenatal development, upkeep of tissue stability, and the progression of diseases. Significant efforts have been invested in constructing genetic models to deplete macrophages in mice, facilitating investigations into the precise functions of tissue-specific macrophages in physiological and pathological contexts. However, the complex heterogeneity within macrophages has hindered the development of an ideal genetic depletion model for these cells as of yet. As a result, Creative Biolabs has established a strategic platform for developing mouse models with macrophage depletion to further explore the intricate mechanisms of macrophages in different environments.

Available Macrophage Depletion Models at Creative Biolabs

• Macrophage Fas-induced apoptosis (MAFIA) transgenic mice: This model enables reversible depletion of macrophages using an inducible genetic system targeting the mouse Csf1r gene. It is valuable for studying macrophage functions in various diseases and tissue processes.
• CD11b-DTR transgenic mice: This model employs a diphtheria toxin (DT) inducible system with the human CD11b promoter driving the human DT receptor fusion. Widely used for studying macrophage biology in tissue homeostasis and disease contexts.
• CD169-DTR strain: The CD169-DTR strain features a sophisticated DT-inducible system with the human DTR controlled by the CD169 sialoadhesin gene promoter. This strain allows for precise conditional ablation of macrophages in specific regions such as the spleen's marginal metallophilic zone, lymph nodes, and bone marrow.
• CD206-DTR mice: The CD206-DTR strain was developed to study the specific roles of M2 macrophages in mice. It provides a valuable tool for investigating the unique functions of both M1 and M2 macrophages in different disease settings.
