Here, we present a protocol for primary, human immune cell isolation and stimulation for lipid mediator profiling. We describe steps for the isolation of monocytes from human leukocyte concentrates via density centrifugation and differentiation/polarization toward M1- or M2-monocyte-derived macrophages (MDMs). We detail stimulation approaches of MDMs with live bacteria or influenza A virus for lipid mediator profiling and sample preparation for subsequent analysis, such as enzyme expression, mRNA analysis, or surface marker determination. For complete details on the use and execution of this protocol, please refer to Jordan et al.1.
Keywords: Cell Biology; Cell isolation; Cell-based Assays; Immunology; Microbiology.
