CD8A and neoplasm: The naphthylacetic acid-modified D-enantiomeric GFFY (D-Nap-GFFY) can form a nanofiber hydrogel which is selectively taken up by antigen-presenting cells, and D-Nap-GFFY-encapsulated T317 (D-Nap-GFFY-T317) enhances dendritic cell maturation and infiltration into tumors, increases CD3+/CD8+ cells in tumors, and inhibits tumor angiogenesis.26
