Mouse peripheral blood mononuclear cells (PBMC) serve as invaluable tools in biomedical research, providing insights into immune responses across diverse strains. For instance, C57BL/6 mice are widely used in immunological studies, such as investigating vaccine-induced resistance or cellular metabolism through flow cytometry and transcriptomic analyses . Similarly, BALB/c mice feature in strain-specific research, aiding in understanding pathogen responses and toxicity evaluations . While DBA/2 strains are noted for genetic cross-studies in immune phenotyping , these models form the backbone for isolating "blank" or untreated PBMC—key to unbiased assessments of immune modulation.
In drug development, mouse PBMC enable robust *in vitro* evaluation of compounds for immunomodulatory effects. PBMC can be cultured under various stimulatory conditions, such as with lipopolysaccharide (LPS) or phytohemagglutinin (PHA), to assess cytokine secretion changes using multiplex assays. For example, studies have shown that stimulants alter cytokine profiles, revealing compound-induced shifts in immune activation and function. This approach directly supports toxicology research, where PBMC exposure to agents like aluminum (Al) *in vitro* demonstrates reduced immunoglobin production and suppressed B-cell and T-cell activation, highlighting potential immunotoxicity risks .
For drug screening, PBMC are integral to high-throughput platforms. Coculture systems with PBMC—such as those involving mesenchymal stem cells (MSC) or cancer-associated fibroblasts—replicate tumor microenvironments, allowing assessment of cell proliferation, survival, and cytotoxicity. PBMC activation in these models enhances tumor-killing efficacy, with killing rates measured through flow cytometry and ELISA; for instance, activated PBMC achieve tumor cell killing rates as high as 20% in optimized assays . Additionally, PBMC support evaluation of cell viability and subset changes, such as increases in regulatory T cells (Treg) or monocyte survival under immunomodulatory conditions, reflecting compound impacts on immune cell health .
Overall, mouse PBMC facilitate reproducible, cost-effective screening of compounds, driving innovations in immunotherapy and toxicology while providing critical data on cellular dynamics—all essential for advancing biomedical breakthroughs.
