We also find that antigen presentation (MHC-1), cell adhesion molecules involved in T cell migration (ADGRE5, SELPLG, SELL), and ligands-receptors associated with activation of inflammatory responses and secretion of pro-inflammatory cytokines (LCK, CD6) were expressed in T cells, indicating the killer potential of T cells against tumor cells (33–35). The gene discussed is CD6; the disease is neoplasm.
