Based on the outstanding expertise and rich experience, Creative Biolabs has specially developed a system approach of TCR generation and optimization for TCR development. Particularly, we offer cytokines release assay service to help customers assess the function of their TCR-modified T cells by determining the cytokines releasing ability.
In recent years, T-cell therapy has yielded impressive clinical results in patients who had previously failed to standard treatments. Adoptively transferred T cells have the capacity to kill antigen-expressing tumor cells and thereby provide a direct cytolytic effector function. Several TCR gene-modified T-cell trials have shown successes. Adoptively transferred T cells not only can directly kill tumor cells to enable fast tumor reduction, but also can initiate late adaptive responses by other compartments of the immune system. TCRs on T-cell surfaces can specifically recognize peptide antigens presented by APCs, leading to the activation of T-cells and a series of functional outcomes such as cytokine production. The release of cytokines by T cells defines a significant part of their functional activity and their ability to produce multiple cytokines has been associated with beneficial immune responses. With the increasing of TCR gene-modified T-cell research and development, evaluating the cytokines release ability of TCR-modified T cells can be quite important for monitoring the function and efficiency.
Creative Biolabs commonly provides our clients the measurement methods including enzyme-linked immunospot assay (ELISpot), intracellular cytokine staining assay (ICS), and flow cytometry, but not limited to them. In response to viruses or tumor antigens, those successfully modified T cells can secrete higher levels of cytokines, such as IFN-γ, IL-12 and GM-CSF. Therefore, Creative Biolabs will focus on these kinds of cytokines and select appropriate methods for customers to analyze these released cytokines.
