Checkpoint-insulated triple-signal artificial antigen-presenting cells drive antigen relay and systemic antitumor immunity

A lab-designed immune cell platform overcomes tumor suppression better than standard approaches, sparking new immunotherapy strategies in mice.

This PNAS study reports a novel artificial antigen-presenting cell platform that circumvents immune checkpoint suppression using triple co-stimulatory signals and an antigen relay mechanism, generating durable systemic antitumor immunity in mouse models. The approach overcomes a key limitation of existing cancer immunotherapy by sustaining T-cell activation against diverse tumor antigens beyond the immunosuppressive microenvironment.
