What does F4 80 mean?
What does F4 80 mean?
F4/80
F4/80 antigen is a mature mouse cell surface glycoprotein expressed at high levels on various macrophages including: Kupffer cells, splenic red pulp macrophages, microglia, gut lamina propria, and Langerhans cells in the skin.
What cells express F4 80?
F4/80 is highly and constitutively expressed on most resident tissue macrophages, including the red pulp macrophages in the spleen, microglia in the brain, Kupffer’s cells in the liver, and Langerhans’ cells in the skin (6).
What is murine macrophage?
The two most convenient sources of primary murine macrophages are the bone marrow and the peritoneal cavity. Resident bone marrow macrophages can be isolated following enzymatic separation of cells from bone marrow plugs and enrichment on 30% fetal calf serum containing medium or Ficoll-Hypaque gradients.
Do monocytes express Ly6G?
Monocytes express Ly6G transiently during bone marrow development, while Ly6G expression in granulocytes and peripheral neutrophils directly correlates with the cell’s level of differentiation and maturation. This hallmark makes Ly6G a good marker for these particular cell populations.
Do macrophages express Ly6C?
However, macrophages are highly heterogeneous and diverse in their origin and function11. Recent studies have shown that macrophage subpopulations are distinguished by differential Ly6C expression, which has been recognized as a superior marker to identify monocyte and macrophage subpopulations14,20,21.
How is EMR1 expressed in the human body?
The epidermal growth factor-like modul-containing, mucin-like hormone receptor 1 (EMR1) is expressed specifically on human blood eosinophils and may serve as a potential target of therapy. A novel, humanized afucosylated anti-EMR1 IgG1 antibody has recently been shown to augment NK cell-mediated killing of eosinophil granulocytes.
Is the EMR1 gene restricted to eosinophils?
EMR1 expression in human is restricted to eosinophils and is a specific marker for these cells. The murine homolog of EMR1, F4/80, is a well-known and widely used marker of murine macrophage populations.
Which is the murine homolog of EMR1 F4 / 80?
The murine homolog of EMR1, F4/80, is a well-known and widely used marker of murine macrophage populations. The N-terminal fragment (NTF) of EMR1 contains 4-6 Epidermal Growth Factor-like ( EGF-like) domains in human and 4-7 EGF-like domains in the mouse.
How does EMR1 regulate the number of ERMES foci?
Here, we demonstrate that the mitochondrial membrane protein Emr1 contributes to regulating the number of ERMES foci. We show that the absence of Emr1 significantly decreases the number of ERMES foci. Moreover, we find that Emr1 interacts with the ERMES core component Mdm12 and colocalizes with Mdm12 on mitochondria.
