在 CAR19 治疗 6 个月后才进行的晚期白细胞单采,获得的残留 CAR19 更少、CAR22 CD4⁺ 初始 T 细胞和中央记忆 T(TCM)细胞更多、效应记忆 T(TEM)细胞更少,且 CD8⁺ TCM 细胞更多;但其临床结局与早期白细胞单采相近。CAR22 应答与较高的转导效率、较多的 CD8⁺ TCM 细胞及较少的 CD8⁺ TEM 细胞相关。
Late leukapheresis (>6 months after CAR19) resulted in less residual CAR19, higher CAR22 CD4+ na ve T and TCM cells, less TEM cells, and higher CD8+ TCM cells, but similar clinical outcomes to those with early leukapheresis. CAR22 responses were associated with higher transduction efficiency and CD8+ TCM and less CD8+ TEM cells.
