Bioluminescent Cell-Based T Cell Activation Assays

Immunotherapy strategies aimed at inducing, strengthening or engineering T cell responses have emerged as promising approaches for the treatment of diseases such as cancer and autoimmunity. T cell activation is initiated by engagement of the TCR/CD3 complex and the co-stimulatory receptor CD28, with TCR/CD3 engagement activating the NFAT pathway and TCR/CD3 + CD28 co-engagement activating NFAT, AP-1 and NF-κB pathways and inducing IL-2 production.

The T Cell Activation Bioassays are bioluminescent cell-based assays that overcome the limitations of existing assays and can be used for the discovery and development of novel biologics such as bispecific antibodies and CAR-T cell therapies.

Representation of the T Cell Activation Bioassay

13791MA_W
The T Cell Activation Bioassay (NFAT and IL-2) each consists of a genetically engineered cell line, TCR/CD3 Effector Cells NFAT (Panel A) or IL-2 (Panel B). When engaged with either an anti-TCR/CD3 stimulus alone or an anti-TCR/CD3 and an anti-CD28 stimulus, receptor-mediated signaling induces luminescence.

Assay Principle

The T Cell Activation Bioassays consist of a genetically engineered Jurkat T cell line that expresses a luciferase reporter (TCR/CD3 Effector Cells) driven by either an NFAT-response element (NFAT-RE) or an IL-2 promoter. When the TCR/CD3 Effector Cells (NFAT) are engaged with an appropriate TCR/CD3 ligand or anti-TCR/CD3 antibody, the TCR transduces intracellular signals resulting in NFAT-RE-mediated luminescence. Similarly, when the TCR/CD3 Effector Cells (IL-2) are co-engaged with an anti-TCR/CD3 and an anti-CD28 stimulus, receptor-mediated signaling results in IL-2 promoter-mediated luminescence.

Prequalified Assay

The bioassay is prequalified according to ICH guidelines and shows the precision, accuracy and linearity required for routine use in potency and stability studies. The bioassay workflow is simple, robust and compatible with 96-well and 384-well plate formats used for antibody screening and drug discovery. Additionally, the bioassay is tolerant to human serum, indicating potential for further development into a neutralizing antibody bioassay.

Advantages

Prequalified According to ICH Guidelines: The bioassays demonstrate the precision, accuracy and linearity required for routine use in potency and stability studies.

Simple and Robust Workflow: Easy to implement with no specialized skills or training required.

Amenable to antibody screening and drug discovery: Run the bioassay in 96-well and 394-well plate formats.

Convenient Product Formats: Choose the product format that meets your experimental and workflow needs.
