Multiple activation of t cells towards tumors
Web1 dec. 2024 · Recent single-cell microscopy recordings on CTL-mediated cytotoxicity towards virus-infected cells [12] and tumor cells in 3D culture and in vivo [13., 14., 15.] have indicated that CTLs kill target cells by delivering several pulses of sublethal hits, the effect of which accumulates over time until the target cell dies. This suggests that CTLs ...
