Figure Legend Snippet: A , ELISA-based analysis of IFNγ, IL-2, GM-CSF and TNFα-secretion of TCR-transduced CD8 + T cells after 24 h incubation with either CD2-sdAb (orange), CD27-sdA (blue) and R3b23-sdAb as a control (grey) in three different tumor cell lines that have been transduced with HLA-B*07:02 (ML2-B7, NB4-B7, HL60-B7). Results of triplicates are depicted with mean +/- standard deviation (sd). B , Proliferation of target tumor cells (624.38 Mel) was monitored by impedance measurement every 30 min for 24 h, after which TCR-transgenic CD8 + T cells and the respective antibody-derived constructs were added to the co-culture. 624.38 Mel cells were seeded at a concentration of 75,000 cells / well and after 24 h 75,000 CD8 + T cells / well were added together with 100 nM of CD2-sdAb (top left), CD7-sdA (top right), anti-CD2-F(ab’) 2 (bottom left) and anti-R3b23-sdAb (bottom right). The left y-axis shows cell-index values of tumor cells, indicated by grey planes, while the right y-axis shows the percentage of lysed tumor cells, indicated by colored lines. C , Depiction of dynamic target-cell lysis after addition of CD8 + T cells and antibody-derived constructs, which have been added at a concentration of 100 nM and 500 nM.

Figure Legend Snippet: A , Experimental setup of in vivo tumor rejection model for CD8 + T cells. NSG mice were subcutaneously (s.c.) injected with ML2-B7 cells in the right flank and ML2-B15 cells in the left flank. After eight days, TCR-transgenic human CD8 + T cells were injected intravenously (i.v.) through the tail vein, followed three days later by i.v. injection of R3-b23-sdAb, OKT11, RPA, CD2-sdAb or CD7-sdAb. Tumor growth was monitored from tumor onset until the end of experiment at day twelve. B, C, Monitoring of tumor growth kinetics of ML2-B15 (B) and ML2-B7 tumors (C) in NSG mice. On day 0, eight days after subcutaneous tumor injection, mice were intravenously injected with TCR 2.5D6-transgenic CD8 + T cells and three days later with either PBS, R3b23-sdAb, CD2-F(ab’) 2 (OKT11), CD2-F(ab’) 2 (RPA-2.10), CD2-sdAb or CD7-sdAb. Kinetics of tumor growth were monitored daily for twelve days post T-cell injection. The experiment was ended at day twelve, at which point all relevant non-control tumors had been fully rejected. Tumor sizes are shown in mm 2 and mean values and SDs are depicted for each group of mice. PBS n = 4, R3b23-sdAb n = 3, CD2-F(ab’) 2 (OKT11) n = 6, CD2-F(ab’) 2 (RPA-2.10) n = 4, CD2-sdAb n = 5, CD7-sdAb n = 5. Significance was calculated using Mann-Whitney test (* p ≤ 0.05, ** p ≤ 0.01, *** p ≤ 0.001)

Figure Legend Snippet: A , Experimental setup for in vivo imaging of ⁶⁸Ga-NOTA-labeled sdAb in NSG mice. ML2-B7 (HLA-matched) and ML2-B15 (irrelevant control) tumors were subcutaneously injected, followed by intravenous injection of TCR-transgenic CD8⁺ T cells (2 × 10⁷ per mouse). Three groups of five mice received either ⁶⁸Ga-NOTA-CD2-sdAb, ⁶⁸Ga-NOTA-CD7-sdAb, or ⁶⁸Ga-NOTA-R3b23-sdAb, and PET/MRI scans were performed one hour post-injection (p.i.). B , PET/MRI images acquired one h p.i. of mice injected i.v. with 68 Ga-NOTA-CD2-sdAb (left) or 68 Ga-NOTA-R3b23-sdAb (right). Exemplary mice are shown in coronal, sagittal and axial orientation (A) or just in coronal orientation (B). 2 x 10 7 TCR-transgenic CD8 + T cells were injected i.v. and the injected dose of applied tracer was 13 ±1MBq per mouse. Scale bar is represented as standardized uptake value (SUV), 0.4 – 1.5 SUV. B = Bladder, K = Kidney. Green arrow = ML2-B7 tumor, white arrow = ML2-B15 tumor. C , Biodistribution of 68 Ga-activity in ML2-B7 and -B15 tumors for mice receiving CD2-sdAb or R3b23-sdAb 1.5 h post injection and after previous PET/MRI image acquisition. Mean %ID/g ± SD is depicted for each group of mice. R3b23-sdAb n = 4, CD2-sdAb n = 4. Significance was calculated using Mann-Whitney test (* p ≤ 0.05).
