Chimeric antigen receptor-engineered T cells (CAR Ts) targeting CD19 have shown unprecedented prognosis in treating hematological cancers. However, the lack of a tumor-specific antigen as the target and an inhospitable tumor environment limit the clinical application of CAR T in solid tumors. Tumor-infiltrating T lymphocytes (TIL) exhibit diverse T cell receptor clonality and superior tumor-homing abilities. Therefore, in our study, human CD19-target TIL CAR-Ts armed with CD3ζ and 4-1BB signaling domains were constructed. Mouse colorectal cancer CT26 cells expressing human CD19 (hCD19+-CT26) were developed to assess the anti-tumor activity of TIL CAR-T cells, both in vitro and in vivo. Compared with splenic CAR T adoptive transfer, TIL CAR-T administration showed superior tumor suppression ability in hCD19+-CT26 tumor-bearing mice. Furthermore, more T cells were found at the tumor site and had lower exhaustion-related inhibitory receptor (T cell immunoglobulin and mucin domain-containing protein 3, Tim3) expression and higher immune memory molecule (CD62L) expression. Overall, we provided an artificial tumor-specific antigen in solid tumors and demonstrated that combined CAR-expressing TIL-Ts (TIL CAR-Ts) exhibited strong anti-tumor activity, with improved T cell infiltration and immune memory. Our humanized tumor antigen presented platform of mice suggests that TIL CAR-T-based adoptive therapy could be a promising strategy for solid cancer treatment.
