MFGE8 and neoplasm: In a similar approach, Morishita et al. designed TEX were transfected with a plasmid encoding streptavidin–lactadherin (SAV–LA) fusion protein, enabling its display on the exosomal surface.[102] This modification allowed for the stable attachment of biotinylated CpG DNA, thereby facilitating the co‐delivery of endogenous tumor antigens and TLR9 agonists to DCs.
