This manuscript describes a detailed protocol for phenotypic and quantitative analysis of resident macrophages from rat kidneys by flow cytometry. The resulting stained cells can be also used for other applications, including cell sorting, gene expression analysis or functional studies, thus increasing the information obtained in the experimental model.

Here, we detail a methodology for the rapid isolation of mouse intestinal dendritic cells (DCs) and macrophages. Phenotypic characterization of intestinal DCs and macrophages is performed using multi-color flow cytometric analysis while magnetic bead enrichment followed by cell sorting is used to yield highly pure populations for functional studies.

In this video, we describe a protocol for the immunostaining and confocal microscopy-based visualization of macrophage extracellular traps (METs) in murine lung tissue. Tissue-resident macrophages are characterized by the expression of the macrophage-specific F4/80 surface glycoprotein marker, while METs are visualized by labeling the MET markers matrix metalloproteinase 9, citrullinated histone H3, and extracellular chromatin.

Characterizing root system traits is one of the areas of research that is still in its infancy, particularly in sugarcane. Integrating multiple approaches to precisely phenotype sugarcane roots leads to comprehensive and holistic results, enabling the utilization of identified traits and mechanisms for conventional and molecular breeding.
FAQs
No single measurement fully captures a macrophage response. Macrophage phenotype characterization therefore combines surface-marker analysis, gene-expression profiling, cytokine measurements, and functional assays. Together, these readouts address cell features, expression changes, mediator production, and functional behavior, giving investigators a more complete basis for distinguishing antimicrobial, inflammatory, regulatory, and tissue-repair programs.
Microbial products and inflammatory mediators can alter macrophage activation and behavior, so characterization compares responses associated with these signals. The resulting pattern helps show whether activity is linked to antimicrobial, inflammatory, regulatory, or tissue-repair programs. This is especially relevant when studying how immune cells respond during infection and how environmental cues influence immune function.
Macrophage responses can contain overlapping features, meaning one cell population may not fit a single label. Treating antimicrobial, inflammatory, regulatory, and tissue-repair activity as flexible programs preserves that complexity and helps investigators interpret mixed measurements. This approach is important in infection and inflammation studies, where environmental signals can produce changing functional patterns.
A useful workflow selects complementary measurements rather than treating one result as decisive. Surface-marker analysis, gene-expression profiling, cytokine measurements, and functional assays can then be considered together to characterize macrophage responses. Comparing these evidence types helps connect molecular or secreted changes with functional behavior and supports a more defensible interpretation of activation programs.
Macrophage phenotype characterization supports studies of host-pathogen interactions, disease progression, vaccine responses, and therapeutic strategies that aim to modify macrophage activity. It can also clarify how macrophage programs relate to inflammation, tissue repair, and infection. These applications make the approach useful for connecting cellular responses with broader changes in disease or immune protection.
Functional assays test what macrophages do, complementing measurements of surface markers, gene expression, and cytokines. Their results help determine whether a molecular profile corresponds to antimicrobial, inflammatory, regulatory, or tissue-repair activity. Including behavioral evidence is valuable when the goal is to connect phenotype with infection responses, inflammation, or tissue repair.
