Mature T-cells circulate in the blood and are found in the paracortex of the lymph nodes.

成熟的T细胞在血液中循环，存在于淋巴结副皮质区。

Each lymph node has B-cells which group together in follicles in the cortex or outer part of the lymph node, along with T-cells in the paracortex just below the cortex.

每个淋巴结都有B细胞；它们集中在皮质的滤泡中，也就是淋巴结靠外的部分，而T细胞存在于皮质下方的副皮质区。
