Abstract

BACKGROUND: Macrophages have heterogeneous phenotypes and complex functions within both innate and adaptive immune responses. To date, most experimental studies have been performed on macrophages derived from bone marrow, spleen and peritoneum. However, differences among macrophages from these particular sources remain unclear. In this study, the features of murine macrophages from bone marrow, spleen and peritoneum were compared. RESULTS: We found that peritoneal macrophages (PMs) appear to be more mature than bone marrow derived macrophages (BMs) and splenic macrophages (SPMs) based on their morphology and surface molecular characteristics. BMs showed the strongest capacity for both proliferation and phagocytosis among the three populations of macrophage. Under resting conditions, SPMs maintained high levels of pro-inflammatory cytokines expression (IL-6, IL-12 and TNF-α), whereas BMs produced high levels of suppressive cytokines (IL-10 and TGF-β). However, SPMs activated with LPS not only maintained higher levels of (IL-6, IL-12 and TNF-α) than BMs or PMs, but also maintained higher levels of IL-10 and TGF-β. CONCLUSIONS: Our results show that BMs, SPMs and PMs are distinct populations with different biological functions, providing clues to guide their further experimental or therapeutic use.

  • Peritoneal macrophages differentiate within the tissue, allowing them to mold to their environment and experience hormonal changes throughout the animal's lifespan.

    “This population was selected over bone-marrow derived macrophages as peritoneal macrophages differentiate within the tissue, which allows them to mold to their environment and experience hormonal changes throughout the animal’s lifespan [29, 31, 32].”

    From Alzheimer’s disease-associated protective variant Plcg2-P522R modulates peripheral macrophage function in a sex-dimorphic manner (2024) · cites this paper as [32]

    The Discussion says peritoneal macrophages are obtained directly from the peritoneum, unlike bone-marrow-derived macrophages that can be fully differentiated in vitro. The Background also suggests that conditions in the peritoneal cavity may contribute to their distinct characteristics. Neither section establishes that peritoneal macrophages differentiate within the tissue or experience hormonal changes throughout the animal’s lifespan. (LLM, conf=0.83)

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.
