An In Vitro Assay to Evaluate the Anti-Tumor Activity of Tumor-Specific CAR T Cells
0 Views •
2025
This video demonstrates an in vitro assay to validate chimeric antigen receptor (CAR) T cell activity. B-cell lymphoma cells expressing CD19 antigen and cytoplasmic luciferase are co-cultured with CD19-specific CAR T cells. CAR binding to CD19 on a tumor induces the CAR T cells to release cytokines and toxins that cause tumor cell cytotoxicity. The CAR T cell activity is evaluated by quantifying the released cytokine and decreased luciferase-mediated bioluminescence in the tumor cells.

An In Vitro Method to Determine the Anti-Apoptotic Activity of Antibodies against TNFα

This video demonstrates a technique for assessing the efficacy of antibodies against tumor necrosis factor-alpha (TNFα), an inflammatory cytokine, through an in vitro bioanalytical approach. TNFα, when introduced to stressed cells, triggers apoptosis. However, binding to the antibodies confines TNFα, averting apoptosis. The degree of apoptosis is quantified using a bioluminescence assay.

Neutrophils play an important role not only in host defense against invading microorganisms, but are also involved in the immune surveillance of tumor cells. Here, we describe techniques related to the isolation of neutrophils with anti-tumor properties and methods for monitoring anti-tumor neutrophil function in vitro and in vivo.
FAQs
CD3 engagement supplies the antigen-receptor-associated activation signal, whereas CD28 provides the essential costimulatory input described for this method. Delivering both signals in the same in vitro system produces a more complete, experimentally controlled T-cell stimulus than examining receptor engagement alone. This paired design supports analysis of downstream function, including proliferation, cytokine production, and differentiation.
Antibody presentation format does not change the molecular targets: both immobilized and bead-bound reagents ligate CD3 and CD28 on T cells. The important experimental feature is coordinated engagement of the receptor-associated signal and costimulatory pathway. Using these defined inputs helps separate general T-cell activation from responses that depend on recognition of a particular antigen.
Researchers can follow several functional outputs after stimulation: signaling, proliferation, cytokine production, differentiation, and changes in activation state. These readouts address complementary questions. Proliferation and expansion indicate cell growth, cytokines reflect functional output, and differentiation reveals changes in T-cell state. Together, they support characterization of primary T-cell responses in controlled experiments.
Antigen-specific stimulation can restrict analysis to responses against a defined antigen, whereas Anti-CD3/28 Activation provides a reproducible, antigen-independent way to engage the core T-cell receptor and costimulatory pathways. That distinction is useful when researchers want to compare overall T-cell function, activation states, or dysfunction without making antigen recognition the experimental variable.
A basic workflow uses primary T cells and a defined antibody presentation format, either immobilized or bead-bound, to engage CD3 and CD28 in vitro. After stimulation, researchers can assess proliferation, cytokine production, differentiation, or broader activation states, and may expand the cells for subsequent characterization. The method therefore links a controlled stimulus to measurable cellular outcomes.
In immunology and infection studies, the method can model T-cell activation states, examine infection-related dysfunction, and provide activated cells for downstream investigation. Its controlled stimulation is also relevant to immunotherapy and cellular-therapy research, where investigators need to characterize or expand primary T cells before studying their function. These uses extend from basic immune analysis to translational cell studies.
