This video demonstrates the priming of primary monocytes into macrophages. Primary human monocytes can be isolated and differentiated to an M1-like pro-inflammatory phenotype using the granulocyte-macrophage colony-stimulating factor (GM-CSF) or to an M2-like anti-inflammatory phenotype using the macrophage colony-stimulating factor (M-CSF).
Protocol
All procedures involving human participants have been performed in compliance with the institutional, national, and international guidelines for human welfare and have been reviewed by the local institutional review board. 1. Isolation of primary human monocytes by immunomagnetic negative selection Collect 40 mL of fresh, human whole blood (from either an HIV+ patient or healthy control) in four 10 mL ethylenediaminetetraacetic acid (EDTA) vacuum tu…
