To investigate the effects of macrophage-mediated trogocytosis on cancer cell fate and its potential for improving immunotherapy.
Utilized a 3D tumor spheroid model with SKOV3 cells to examine interactions with Her2CAR macrophages.
Observed trogocytosis and phagocytosis rates in co-culture with cancer cells.
Assessed cancer cell death and alterations in the transcriptomic profile following macrophage interaction.
Higher rates of trogocytosis were observed than phagocytosis by Chimeric Antigen Receptor macrophages.
Significant reduction in tumor spheroid size with Her2CAR macrophages after 5 days of co-culture.
Delayed apoptotic cell death in cancer cells was documented after sustained trogocytic attacks.
