New Research

Immunotherapy can effectively activate the immune system and reshape the tumor immune microenvironment, which has been an alternative method in cancer therapy besides surgery, radiotherapy, and chemotherapy. However, the current clinical outcomes are not satisfied due to the lack of targeting of the treatment with some unexpected damages to the human body. Recently, cell membrane-based bioinspired nanoparticles for tumor immunotherapy have attracted much attention because of their superior immune regulating, drug delivery, excellent tumor targeting, and biocompatibility. Together, the article reviews the recent progress of cell membrane-based bioinspired nanoparticles for immunotherapy in cancer treatment. We also evaluate the prospect of bioinspired nanoparticles in immunotherapy for cancer. This strategy may open up new research directions for cancer therapy.

Broad Interest

Recently, photothermal-immuno synergistic therapy under mild temperature (~ 45 °C) has got broad interest in cancer treatment. Inhibition the intratumorally HSPs production is the key to accomplish highly efficient and mild photothermal therapy. In this work, we developed biomimetic nanoterminators with mature DCs functions by coating the mature dendritic cell membrane on photothermal nanoagents. As-prepared nanoterminators could automatically locate on T cell in the complex tumor-immune microenvironment and promote the T cells proliferation, activation and cytokine secretion, which could not only inhibit the expression of heat shock proteins to cooperate on highly efficient mild photothermal therapy (~42°C), but also promote tumor apoptosis during the treatment. More importantly, this nanoterminator could serve as vaccine to trigger anti-tumor immune response of the whole body, which would be promising to long-life tumor inhibition and termination.

Abstract Objective To investigate the molecular characteristics in tumor immune microenvironment that affect long-term survival of patients with pancreatic adenocarcinoma (PAAD). Methods The tumor related genetic features of a female PAAD patient (over 13-year survival) who suffered from multiple recurrences and metastases, and six operations over one decade were investigated deeply. Genomic features and immune microenvironment signatures of her primary lesion as well as six metastatic tumors at different time-points were characterized. Results High-frequency clonal neoantigenic mutations identified in these specimens revealed the significant associations between clonal neoantigens with her prognosis after each surgery. Meanwhile, the TCGA and ICGC databases were employed to analyse the function of KRAS G12V in pancreatic cancer. Conclusions The genomic analysis of clonal neoantigens combined with tumor immune microenvironment could promote the understandings of personalized prognostic evaluation and the stratification of resected PAAD individuals with better outcome.
