CD11c, a member of the integrin β2 adhesion molecular family, is expressed on the surface of myeloid dendritic cells and other immune cells.[57] It can trigger the activation and differentiation of naïve T cells into effector cells through antigen presentation, which can have an impact on the occurrence and development of BC.[58] CD127 on CD45RA‐ CD4 not Treg cells, the surface receptor CD127, is the Interleukin-7 (IL-7) receptor α chain. Here, CD4 is linked to breast cancer.
