CD8/Cd68 in Breast
What will the Macrophage story be?Specific Macrophage markers are needed.
Gabrilovich et al. Nature Reviews Immunology 12, 253-268 (April 2012)
The presence of the mannose receptor (CD206) suggests that these cells are activated M2
CD124 is interleukin-4 receptor. This is another marker for M2
CD206 and CD124 are markers for Macrophages M2 CD206 and CD124 are markers for Macrophages M2
Predina J et al. PNAS 2013; 110:E415-24
Macrophages express higher levels of CD206 and CD124 in recurrent tumors than in primary tumors.
