Figure 1. The schematic representation showed that the anti-tumour immunity was enhanced by immunomodulatory macroporous scaffolds. Sustained release of scaffolds can recruit endogenous T cells, whereas the presentation of surface-conjugated activation cues and the sustained release of IL-2 can activate recruited T cells. Sustained release of TGF-β depletes Tregs in tumours. IL-2: interleukin-2; TGF-β: transforming growth factor β; TGFβ1: transforming growth factor β 1; Treg: regulatory T cell.
