CD171-specific CAR-T cell treatment leads to transient antigen loss. a Scheme of the experimental process. Time-dependent cell surface expression of CD171 on WERI-Rb1 (b) and RB355 cells (c) following 3-day co-culture with CD28-long spacer CAR-T cells and on day 10 and 14 after CAR-T cells removal (mean ± SD, n = 3)
