Abstract

Tumor-infiltrating lymphocytes (TIL) obtained from human melanomas can specifically lyse autologous tumor in vitro and mediate tumor regression in vivo. To develop more effective therapeutic reagents and to further understand the T-cell response to tumors, the diversity of T-cell receptors (TCRs) involved in melanoma antigen recognition has been studied. The TCR variable (V) genes, joining (J) segments, and N diversity regions used by five clonal lines and one highly oligoclonal, melanoma-specific, CD8+ TIL line were examined utilizing PCR amplification with V gene subfamily-specific primers and anchor PCR. The TIL lysed multiple allogeneic melanomas expressing matched surface major histocompatibility complex class I molecules. TCR analysis confirmed the clonal nature of the TIL lines; however, the TCR repertoire was diverse. Even among the three HLA-A2 restricted TIL (TIL 1200, TIL F2-2, and TIL 5), no common V gene usage was found. Comparison of the third complementarity-determining regions of the TCRs from the HLA-A2 restricted TIL revealed no homology. Results presented here identify T-cell clonotypes that recognize epitopes on highly prevalent, shared melanoma tumor-associated antigens presented in the context of HLA- 855, HLA-A1, and HLA-A2. These T cells and the antigens they recognize represent important components for the design of new immunotherapies for patients with advanced melanoma.
