(A) Expression of CSPG4 and gp100 on human melanoma cell lines was detected by flow cytometry using specific monoclonal antibodies and FITC-conjugated secondary antibody. Expression of CD146 was detected using FITC-conjugated mouse anti-human CD146. Gray lines: secondary antibody alone or isotype control; Black lines: anti- CSPG4, gp100 or CD146, as indicated. (B) 1G2 (HLA-A2+/ gp100154–162- reactive) T cell line was co-cultured with HLA-A2+ (M579-A2 and 624mel) or HLA-A2− (M171 and M579) melanoma cells. CSPG4 was detected on CD8+ lymphocytes by staining with specific monoclonal antibodies, followed by flow cytometry. (C) 2E2, 2C7 and 1H8 (all A2/MART-126–35- reactive) T cell clones were co-cultured and analyzed as described in B. (D) 1H8 T cell clone was co-cultured with melanoma cell lines as described in B. Presence of gp100 and CD146 on CD8+ cells was monitored by flow cytometry. One representative experiment of five performed is shown. (E) The four following cell lines were co-cultured: MART-126–35-reactive T cells (2D6), a non-relevant MUC-163–71-specific T cell line (line 33), melanoma cells (526mel) and MUC-163–71 peptide-pulsed T2 cells. CSPG4 and CD107A were detected on CD8+ lymphocytes by staining with specific monoclonal antibodies, followed by flow cytometry. To enable separate gating, the two lymphocyte populations 2D6 and line33 were pre-labeled with PKH67 and PKH26, respectively.

PBMCs from melanoma patient 171 were cultured for 12 days in the presence of irradiated autologous melanoma (M171). Following, the cells were co-cultured with autologous (M171) or irrelevant (624mel) melanoma cells. CSPG4 was monitored on CD8+ lymphocytes by staining with specific monoclonal antibodies, followed by flow cytometry. (B) PBMCs from melanoma patient 579 were cultured for 12 days in the presence of irradiated autologous melanoma (M579). Following, the cells were co-cultured with autologous (M579) or irrelevant (M171) melanoma cells. IFN-γ secretion of non-stimulated and 12 day-stimulated cells after re-stimulation with irrelevant melanoma (624mel, empty bar) or autologous melanoma (M579, filled bar) was evaluated by ELISA. (C) Presence of CSPG4 was monitored on CD4+ lymphocytes derived from PBMCs (patient 579), 12 days after stimulation with autologous melanoma, by staining with specific monoclonal antibodies followed by flow cytometry.

(A) TIL from melanoma patient 412 were cultured for 12 days in the presence of irradiated autologous melanoma. Expanded cells were co-cultured with HLA-A2-matched melanoma (624mel, M579-A2) or HLA-A2-mismatched melanoma cells (M171, M579). CSPG4 was monitored on CD8+ lymphocytes by staining with specific monoclonal antibodies followed by flow cytometry. One representative experiment of three performed is shown. (B) Melanoma antigens gp100 (in patients 1 and 2) and CSPG4 (in patient 3) were monitored on CD4+ and CD8+ TIL 4 days after tumor resection from the patient (the minimal time required for TIL expansion in the culture medium). Cells were stained with specific monoclonal antibodies followed by flow cytometry. Dot plots are the results of tumor antigen and background staining for each individual patient. Bars summarize the data from all three patients. Gray bars represent background staining with secondary antibody only (patient 1 and 2), or with isotype (patient 3). Black bars represent specific staining with anti-melanoma antigen specific Ab.

TIL from three melanoma patients, M431, M412 and M209 (A, B and C respectively), were stimulated for 12 days with HLA-A2-matched melanoma cells and sorted to CSPG4-imprinted (CSPG4+/CD8+) and CSPG4-negative (CSPG4−/CD8+) by flow cytometry. Sorted cells were expanded in the presence of anti-CD3 antibody and co-cultured with HLA-A2-matched melanoma (526mel) or irrelevant (888mel) melanoma cells and analyzed for IFN-γ and TNF-α secretion by intracellular staining. The results of one out of three experiments are shown.
