To identify equivalent clusters across BC and blood γδ-T datasets, we used scID (Boufea et al, 2020) which revealed that BC γδ-T.1 cluster was equivalent to blood c.γδ3 cluster (and consistent with both being marked by CD16 and positive for IFNγ) and BC γδ-T.3 cluster was equivalent to blood c.γδ5 cluster (and consistent with both being marked by CCR6 and positive for IL17A) (Figs 4B and C, 1E, and 3E). This evidence concerns the gene CCR6 and breast cancer.
