Phenylboronic acid modified nanoparticles simultaneously target pancreatic cancer and its metastasis and alleviate immunosuppression

Pancreatic ductal adenocarcinoma is one of the most lethal malignant tumors, its drug resistance, immunosuppression and metastasis makes the traditional chemotherapy and immunotherapy inefficient. Here we confirmed a 3-aminophenylboronic acid-modified low molecular weight heparin-D-α-tocopheryl succinate micellar nanoparticle (PBA-LMWH-TOS NP, PLT NP) could inhibit orthotopic pancreatic tumor and its spontaneous metastases. The small particle...
