For example, Liu et al. found that the LSECtin expressed on TAMs could interact with its receptor butyrophilin subfamily 3, member A3 (BTN3A3) and enhance the stemness of BC cells; further, when applying the anti-BTN3A3 antibody, 5E08, the stemness of BC cells could be attenuated [100]. This evidence concerns the gene BTN3A3 and breast cancer.
