What is CD206?

The macrophage mannose receptor (MR, CD206) is a C-type lectin expressed predominantly by most tissue macrophages, dendritic cells and specific lymphatic or endothelial cells. It functions in endocytosis and phagocytosis, and plays an important role in immune homeostasis by scavenging unwanted mannoglycoproteins.

What is CD206 a marker for?

CD206, also known as mannose receptor C type 1 (MRC1), is a cell-surface protein abundantly presents on selected populations of macrophages and dendritic cells. As for macrophages, CD206 is normally expressed on the M2 but not M1 subtype and therefore serves as a useful marker to identify the M2 phenotype.

Is CD206 intracellular?

CD206 has an altered intracellular processing and is trapped within the endoplasmic reticulum, making it unable to perform endocytosis.

Do monocytes express CD206?

Subpopulations of monocytes have distinct surface markers, such as CD206 and CD115, and functions.

What is a Type 2 macrophage?

M2 macrophages mainly secrete Arginase-I, IL-10 and TGF-β and other anti-inflammatory cytokines, which have the function of reducing inflammation and contributing to tumor growth and Immunosuppressive function. It plays an important role in wound healing and tissue repair.

Can macrophages be found in blood?

Essentially, macrophages may be described as large white blood cells found in body tissues. In blood, they were traditionally said to exist as monocytes that differentiate into different types once they leave blood circulation and migrate to damaged tissue.

Do macrophages express CD16?

Human monocytes express high levels of CD14 and low CD16, while macrophages express low CD14 and high CD16. If interested, you can also use CCR5 as monocytes have very low expression of the chemokine receptor, while macrophages express very high levels.

Are CD206 + M2-like macrophages involved in progenitor and stem cell niche activity?

As macrophages are reportedly involved in the regulation of progenitor activity or stem cell niche activity 3, 6, 18, 19, 20, we investigated the possible involvement of CD206 + M2-like macrophages in the control of APs proliferation. As shown in Fig. 3a]

How are CD163 and CD206 shed from the macrophages?

The binding pocket of 4-SO4-GalNAc of the mannose receptor has pH-dependent conformational change. These data indicate that CD163 and CD206 are shed from the macrophages by very different mechanisms potentially involving distinctive inflammatory processes.

Is CD206 a biomarker for hepatocellular carcinoma (HCC) prognosis?

MRC1 and S100A9 may contribute to the determination of the mechanisms and screening involved in CRC. Findings show that CD206 was highly expressed in the hepatocellular carcinoma (HCC) tissues and indicate that CD206 is a potential biomarker for predicting HCC prognosis.

Does galectin-9 bind to macrophage mannose receptor CD206?

The expression of macrophage mannose receptor, CD206, predicts prognosis in patients with pulmonary tuberculosis. Galectin-9 binds to CD206 on M2 macrophages, which appear to drive angiogenesis and the production of chemokines that support melanoma growth.
