The reactivation and clonal expansion of tumor-specific antigen (TSA)-reactive T cells are critical to the success of tumor-infiltrating lymphocyte (TIL)-based therapies. In many emerging personalized cancer therapies, the key to success is to find the elusive TSA-reactive T cells, then create more of these cells outside the patient's body, and then reintroduce them for tumor treatment. However, an unmet need in this field is the ability to identify useful tumor-infiltrating immune cells more quickly and accurately. Due to its heterogeneous composition, there is no reliable marker that can specifically identify the composition of TSA-responsive T cells.
At Creative Biolabs, we have developed a new technology, FucoID, named after the enzyme fucosyltransferase, which plays a key role in "labeling" the surface of the desired immune cells so that they can be seen and captured. Through this interaction-dependent labeling method, the universal FucoID platform can detect endogenous antigen-specific T cells to study their biological characteristics. Featuring genetic manipulation-free and fast turnover cycle characteristics, FucoID should have the potential to accelerate the pace of personalized cancer treatment.
FucoID Platform: A Fast, Precise Tool Identifies Tumor-Targeting T Cells
FucoID, tumor-lysate primed DCs presenting TSAs, acts as a "living" tetramer, equipped with an enzyme that induces proximity-based transfer of fucosylated biotin (Fuc-Bio) tags to the surface of T cells that interact with the DCs. Specifically, the enzyme is loaded on dendritic cells, which are immune cells that can present tumor-specific substances to the required T cells. When cells interact, enzymes transfer tags to anti-tumor cells, so scientists can detect them with fluorescent probes and extract them from samples.

Can FucoID technology be integrated with other immunotherapy platforms?
FucoID can complement a variety of immunotherapy platforms, such as CAR-T cell development, immune checkpoint assays, and neoantigen discovery. This integration enhances the efficiency of developing personalized therapies by streamlining T cell isolation and validation processes.
How does FucoID technology specifically identify TSA-reactive T cells without genetic manipulation?
FucoID employs interaction-dependent labeling by loading dendritic cells (DCs) with tumor-specific antigens and the enzyme fucosyltransferase. When TSA-reactive T cells interact with these DCs, the enzyme transfers biotin-labeled fucosyl groups to the T cells, enabling precise identification without altering cellular genetic structures.
What are the limitations of FucoID technology in current research applications?
While FucoID excels in precision and speed, its effectiveness can be influenced by sample quality and the efficiency of dendritic cell priming. Additionally, its use in highly heterogeneous tumor microenvironments may require further optimization to ensure comprehensive detection of all TSA-reactive T cells.
Can FucoID technology be applied to rare tumor types or less common cancers?
Yes, FucoID is adaptable to a wide variety of cancer types, including rare malignancies, by customizing dendritic cell priming with tumor-specific lysates. This flexibility allows researchers to isolate TSA-reactive T cells even in unique or underexplored tumor contexts.
