摘 要:Cell therapy is a promising strategy for cancer ***,its therapeutic efficiency remains limited due to the complex and immunosuppressive nature of tumor *** this study,the“cell-chemotherapystrategy was presented to enhance antitumor efficacy.M1-type macrophages,which are therapeutic immune cells with both of immunotherapeutic ability and targeting ability,carried sorafenib(SF)-loaded lipid nanoparticles(M1/SLNPs)were developed.M1-type macrophages were used both as therapeutic tool to provide immunotherapy and as delivery vessel to target deliver SF to tumor tissues for chemotherapy simultaneously.M1-type macrophages were obtained by polarizing macrophages using lipopolysaccharide,and M1/SLNPs were obtained by incubating M1-type macrophages with *** accumulation of M1/SLNP was increased compared with SLNP(p0.01),which proved M1/SLNP could enhance tumor targeting of *** increased ratio of M1-type macrophages to M2-type macrophages,and the CD3^+CD4^+T cells and CD3^+CD8^+T cell quantities in tumor tissues after treatment with M1/SLNP indicated M1/SLNP could relieve the immunosuppressive tumor *** tumor volumes in the M1/SLNP group were significantly smaller than those in the SLNP group(p0.01),indicating M1/SLNP exhibited enhanced antitumor ***,M1/SLNP showed great potential as a novel cellchemotherapeutic strategy combining both cell therapy and targeting chemotherapy.
