New models and assays that would improve the early drug development process for next-generation anti-tuberculosis drugs are highly desirable. Here, we describe a quick, inexpensive, and BSL-2 compatible assay to evaluate drug efficacy against Mycobacterium tuberculosis that can be easily adapted for high-throughput screening.

Understanding the malignant behavior of cancer requires creating accurate models of how tumor cells interact with components of the tumor microenvironment, such as macrophages. Here we describe two methods to study glioblastoma cell interaction with tumor associated macrophages and microglia where the effect on glioblastoma invasion is assessed.

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.

A protocol is presented for cell culture of macrophage colony-stimulating factor (M-CSF) differentiated human monocyte-derived macrophages. The protocol utilizes cryopreservation of monocytes coupled with their bulk differentiation into macrophages. Then harvested macrophages can then be seeded into culture wells at required cell densities for carrying out experiments.

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
PMA activates protein kinase C signaling in THP-1 cells, promoting adherence and the development of macrophage-like characteristics. This induced state makes the cells suitable for experiments that require an adherent immune-cell model rather than undifferentiated monocytic cells. The resulting system supports investigations of macrophage functions, including phagocytosis, inflammatory cytokine production, and pathogen-related host responses.
Adherence provides a practical feature for handling the differentiated cells during experimental analysis. It helps establish a macrophage-like model in which researchers can examine cellular responses to pathogens, immune signals, or interventions. Because PMA-linked protein kinase C activation promotes both adherence and macrophage-like characteristics, these changes are central to preparing the cells for downstream immunology and infection studies.
THP-1 macrophages offer greater consistency and scalability, but they do not fully reproduce primary macrophage behavior. Results therefore reflect responses from an experimentally tractable cell model rather than every feature of macrophages in their natural biological context. This distinction matters when interpreting immune signaling, infection outcomes, or treatment effects and when judging how broadly findings may apply.
A typical workflow begins with the THP-1 monocytic leukemia cell line, followed by exposure to PMA to activate protein kinase C signaling. The cells then become adherent and acquire macrophage-like characteristics, creating a prepared model for downstream assays. Researchers can subsequently examine functions such as phagocytosis, cytokine production, pattern-recognition receptor signaling, or responses to infection.
These cells can provide several complementary readouts of innate immune activity. Researchers may assess phagocytosis, measure inflammatory cytokine production, or investigate signaling through pattern-recognition receptors, which detect features associated with microbes. The model can also reveal how macrophage-like cells interact with bacteria, viruses, and other pathogens, linking cellular mechanisms to broader host-response studies.
They are useful when investigators need a consistent, scalable human cell system for examining host responses to infection. Studies can use the model to explore interactions with bacteria, viruses, and other pathogens or to evaluate antimicrobial and anti-inflammatory interventions. Its reproducibility supports comparative experiments, while the known difference from primary macrophages guides cautious interpretation of biological relevance.
