As target tumor antigens of our CAR T cell therapy, we selected the chondroitin sulfate proteoglycan 4 (CSPG4) and the B7-homolog 3 (B7-H3), as they are both highly and homogeneously expressed on different types of thyroid carcinoma cell lines and tissues, including ATC. Here, CD276 is linked to thyroid gland carcinoma.
