The number of mature dendritic cells (DC) was decreased in OSCC compared with OED lesions suggesting that either these cells might have migrated to lymph nodes to present the tumour antigens and activate the immune system or cytokines secreted by the tumour microenvironment are inhibiting the adequate maturation of DLC. The numbers of pDC were significantly increased in the OSCC group compared with the OED group. This suggests they may play an important role in the defence against tumours although it is not clear whether this is promoting or inhibiting malignant progression.
