Target-specific probes represent an innovative tool for analyzing molecular mechanisms, such as protein expression in various types of disease (e.g., inflammation, infection, and tumorigenesis). In this study, we describe a quantitative three-dimensional tomographic assessment of intestinal macrophage infiltration in a murine model of colitis using F4/80-specific fluorescence-mediated tomography.

In this video, we demonstrate a cytotoxicity assay to assess Cryptococcus neoformans, a pathogenic fungus, infection in macrophages. The cytotoxicity is determined by the release of cytoplasmic lactate dehydrogenase enzyme due to macrophage lysis caused by Cryptococcus neoformans infection.

The article describes a readily easy adaptive in vitro model to investigate macrophage polarization. In the presence of GM-CSF/M-CSF, hematopoietic stem/progenitor cells from the bone marrow are directed into monocytic differentiation, followed by M1 or M2 stimulation. The activation status can be tracked by changes in cell surface antigens, gene expression and cell signaling pathways.

This video demonstrates the lactate dehydrogenase assay to detect inflammasome-mediated macrophage death. The macrophages are exposed to lipopolysaccharide for priming, followed by exposure to nigericin to cause inflammasome-induced cell death, which is determined by the lactate dehydrogenase assay.

Macrophages play a central role in homeostasis and pathology in many tissues. The protocol presented here describes methods for depleting macrophages in vivo, deriving polarized macrophages from bone marrow aspirates, and adoptively transferring macrophages into mice. These techniques allow determination of the role that polarized macrophages play in health and disease.
FAQs
Morphology provides visual cellular context, while macrophage-associated surface or intracellular markers supply additional evidence. Using both types of information can help distinguish macrophages from other immune cells more reliably than relying on a single feature. This combined assessment is especially valuable when researchers need to determine where macrophages are present and how their characteristics change during infection or inflammation.
Surface and intracellular markers can provide complementary evidence when researchers characterize macrophages. Examining these marker categories alongside morphology helps distinguish macrophages from other immune cells and can support assessment of activation state. The value is greatest when marker patterns are interpreted with functional information, such as phagocytic activity, rather than treated as the sole basis for biological conclusions.
Phagocytic activity adds functional information to marker-based characterization. It can indicate how macrophages respond in a biological setting and help researchers assess activation alongside cellular identity. Including this measurement is useful in infection studies because it connects the presence of macrophages with their response to pathogens, rather than describing the cells only through morphology or marker expression.
Reliable identification allows researchers to attribute observed cellular responses to macrophages with greater confidence. This supports investigations of polarization, pathogen responses, inflammatory processes, and interactions between host cells and infectious agents. Accurate detection also helps connect macrophage location and abundance with tissue damage or treatment effects, making comparisons between biological conditions more interpretable.
A detection workflow may combine cellular morphology with immunostaining, flow cytometry, and analysis of phagocytic activity. These approaches provide complementary ways to characterize macrophages in tissues, cell cultures, and other biological samples. The selected combination depends on whether the study needs information about cellular appearance, macrophage-associated markers, functional activity, or changes in activation state.
A practical interpretation workflow begins with cellular morphology, continues with macrophage-associated surface or intracellular markers, and then considers phagocytic activity when functional characterization is needed. Researchers can compare these findings with pathogen exposure, inflammatory changes, tissue damage, or treatment conditions. This layered approach connects macrophage identity with activation and response without relying on one measurement alone.
Researchers use detection results to locate macrophages, quantify their responses to pathogens, and evaluate inflammatory processes. The same measurements can help assess tissue damage, treatment effects, and macrophage polarization. By relating macrophage presence or activity to these outcomes, studies can examine how innate immune responses develop during infection and how those responses change under different experimental conditions.
