CC chemokine receptor 7 is known to influence the migration of activated dendritic cells to regional lymph nodes and appears to play a similar role in gastric, oesophageal and head and neck cancers (Mashino et al, 2002; Ding et al, 2003; Wang et al, 2004; Yan et al, 2004). The gene discussed is CCR7; the disease is head and neck cancer.
