Characterization of CD44v6.CAR T cells used for functional analysis. (A) CAR expression in transduced T lymphocytes detected with the anti-LNGFR mAb C40-1457. Plots of a representative experiment are shown on the left. On the right, means with SDs of the results obtained with eight independent donors are shown. Paired t-test on LNGFR expression was statistically significant for CD44v6-NWN2 (p ≤ 0.05) and CD44v6-NMS (p ≤ 0.05) compared with CD44v6-NWL cells. (B) T cell memory phenotype was defined based on CD45RA and CD62L expression at day 10 after transduction. Plots of a representative donor are shown on the left. On the right, means with SDs of the results obtained with eight independent donors are shown. Paired t-test on TSCM was statistically significant for untransduced (UT; p ≤ 0.0001), CD44v6-NWN2 (p ≤ 0.001), CD44v6-NMS (p ≤ 0.001), and CD19-NWL (p ≤ 0.01) cells, compared with CD44v6-NWL cells. TSCM (CD45RA+/CD62L+ memory stem T cells), TCM (CD45RA/CD62L+ central memory T cells), TEM (CD45RA/CD62L effector memory T cells), TEMRA (CD45+/CD62L effector memory RA T cells).
