Both sensitivity and specificity of detection by PCR were much better than smear or culture techniques. Our results demonstrated that PCR technique is one of the useful tools in early(More)
CD8(+) T cells play important roles in anti-tumor immunity but distribution profile or functional characteristics of effector memory subsets during tumor progression are unclear. We found that, in oral squamous carcinoma patients, circulating CD8(+) T cell pools skewed toward effector memory subsets with the distribution frequency of CCR7(-)CD45RA(-)CD8(+)(More)
