It is not obvious why these two studies buck the trend and suggest that CCR7 is the good guy; however, a recent bioinformatics study looked at various chemokine receptor expression patterns, including CCR7 expression, in relation to NSCLC stage compared to normal tissue and reported that CCR7 was expressed at all stages with higher expression in early stages that tails off as the tumor progresses [221]. Here, CCR7 is linked to neoplasm.
