T cell activation assay

Antigen specific T cell activation assay is one of the technologies we can provide during the one-stop service which can activate CAR-T cells for further downstream research or clinical trials. T cell activation requires at least two signals to be fully activated. The first signal is provided by the interaction of T cell antigen-specific receptor and the antigen-major histocompatibility complex (MHC).  <br>https://www.creative-biolabs.com/car-t/antigen-specific-t-cell-activation-assay.htm

Presentation Transcript

  1. T Cell Activation assay https://www.creative-biolabs.com/car-t/

  2. As an excellent service leader in the field of antibody development and immunotherapy, Creative Biolabs now offers one-stop CAR-T therapy development service which has become a promising approach to antitumor therapy. Antigen specific T cell activation assay is one of the technologies we can provide during the one-stop service which can activate CAR-T cells for further downstream research or clinical trials.

  3. Background T cell activation requires at least two signals to be fully activated. The first signal is provided by the interaction of T cell antigen-specific receptor and the antigen-major histocompatibility complex (MHC). The second signal is provided by co-stimulatory receptors like CD28. In engineered CAR-T cell, CAR consists of specific scFv and signaling endodomains of CD3ζ, CD28, and 4-1BB. Creative Biolabs offers one-stop CAR-T service from basic research to clinical trials and beyond, and antigen specific T cell activation assay has been a vital technology in evaluating the activation activities of different CAR-T cell products at preclinical stage.

  4. Assay of Antigen Specific T Cell Activation CAR-modified T cells can recognize tumor cells via binding of the CAR to its tumor-associated antigen (TAA) independent of TCR-MHC/peptide interactions, and the engineered signaling endodomains can help T cells be activated and persistent. As a result, T cells are activated and thus they can efficiently eliminate tumor cells by the secretion of perforin and granzymes as well as the expression of FasL and tumor necrosis factor-related apoptosis inducing ligand (TRAIL). In addition, other tumor-infiltrating immune cells can be activated by the secretion of various cytokines.

  5. Creative Biolabs offers this assay to detect the following downstream activities to reflect the tumor antigen specific T cell activation. ➢ T Cell Expansion ➢ Upregulation of T Cell Surface Activation Markers ➢ Differentiation Into Effector Cells ➢ Cytokine Production or Cytotoxicity ➢ Induction of Apoptosis
