Figure 1 shows FACS analysis of Siglec-7 antibody binding to human primary dendritic cells compared to isotype control.

The endpoint after 30 h was normalized to the isotype control (gray bars) and the percent aggregated TDP-43 was calculated for ACI-7069-633B12-AM (dashed gray bars). Mean ± SD of three independent experiments are shown and statistical differences between isotype control and ACI-7069-633B12-AM (IgG2a variant) were analyzed by Welch's t-test (*** p < 0.001).

Figure 2 Anti-Siglec-7 antibodies 4E3 and 10B5 can down-regulate the cell surface expression of Siglec-7 on primary human dendritic cells.

The endpoint after 30 h was normalized to the isotype control (gray bars) and the percent aggregated TDP-43 was calculated for ACI-7069-633B12-AM (dashed gray bars). Mean ± SD of three independent experiments are shown and statistical differences between isotype control and ACI-7069-633B12-AM (IgG2a variant) were analyzed by Welch's t-test (*** p < 0.001).

Figure 3 Anti-Siglec-7 antibodies 10B5 and 4E3 inhibit PD-L1 and PD-L2 (PD-1 ligand), B7-H3 (strong T cell checkpoint inhibitory MDSC surface substance), CD200R (inhibiting signaling receptor) and CD163 and CD206 (M2-type marker).

The endpoint after 30 h was normalized to the isotype control (gray bars) and the percent aggregated TDP-43 was calculated for ACI-7069-633B12-AM (dashed gray bars). Mean ± SD of three independent experiments are shown and statistical differences between isotype control and ACI-7069-633B12-AM (IgG2a variant) were analyzed by Welch's t-test (*** p < 0.001).
