Abstract

We generated three populations of macrophages (Mφ) in vitro and characterized each. Classically activated Mφ (Ca-Mφ) were primed with IFN-γ and stimulated with LPS. Type II-activated Mφ (Mφ-II) were similarly primed but stimulated with LPS plus immune complexes. Alternatively activated Mφ (AA-Mφ) were primed overnight with IL-4. Here, we present a side-by-side comparison of the three cell types. We focus primarily on differences between Mφ-II and AA-Mφ, as both have been classified as M2 Mφ, distinct from Ca-Mφ. We show that Mφ-II more closely resemble Ca-Mφ than they are to AA-Mφ. Mφ-II and Ca-Mφ, but not AA-Mφ, produce high levels of NO and have low arginase activity. AA-Mφ express FIZZ1, whereas neither Mφ-II nor Ca-Mφ do. Mφ-II and Ca-Mφ express relatively high levels of CD86, whereas AA-Mφ are virtually devoid of this costimulatory molecule. Ca-Mφ and Mφ-II are efficient APC, whereas AA-Mφ fail to stimulate efficient T cell proliferation. The differences between Ca-Mφ and Mφ-II are more subtle. Ca-Mφ produce IL-12 and give rise to Th1 cells, whereas Mφ-II produce high levels of IL-10 and thus, give rise to Th2 cells secreting IL-4 and IL-10. Mφ-II express two markers that may be used to identify them in tissue. These are sphingosine kinase-1 and LIGHT (TNF superfamily 14). Thus, Ca-Mφ, Mφ-II, and AA-Mφ represent three populations of cells with different biological functions.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
