TNFRSF13C and neoplasm: Analysis of predicted MAC-MT interactions with other immune cells based on receptor-ligand expression using CellPhoneDB (Vento-Tormo et al., 2018) demonstrated that MAC-MT within tumor samples had increased expression of the gene encoding BAFF (TNFSF13B) with the potential to support BAFF-R-expressing B cells (Figures 5H and S7D).
