Research progress in drugs targeting tumor associated macrophage / 药学学报

Tumor brings great threat to human public health. In recent years, incidence rate and mortality of tumor were rapidly increased in the world. Anti-tumor therapies have undergone the development of cytotoxic therapy, targeted therapy, and immunotherapy. Among them, tumor immunotherapy is rapidly developed and becomes an important anti-tumor therapy in recent years, although it also brings some related side effects. Tumor microenvironment (TME) is composed of immune cells, vascular vessels, fibroblasts, the extracellular matrix, etc. TME significantly affects the efficacy of immunotherapy. Macrophages in the TME are named as tumor associated macrophages (TAMs). Recently, increasing studies have shown that TAMs play an important role in the regulation of tumor immunity, especially in tumor immune surveillance and immune escape. Currently, more and more anti-tumor immunotherapy strategies targeting TAMs are at the development stage. Based on the important role of TAMs in the TME and their potential as therapeutic targets in tumor immunotherapy, we first reviewed the subtypes and functions of TAMs, as well as the roles of TAMs in tumors. Furthermore, we summarized the research progress on anti-tumor strategies targeting TAMs and the current status of drug targeting TAMs. The current review will provide new ideas and novel insights for tumor immunotherapy.

Progress on targets and therapeutic drugs for pancreatic cancer / 药学学报

Pancreatic cancer is a highly malignant tumor with a poor prognosis. It is very hard to treat pancreatic cancers for their high heterogeneity, complex tumor microenvironment, and drug resistance. Currently, gemcitabine plus nab-paclitaxel, capecitabine and FOLFIRINOX are standard chemotherapy for resectable or advanced metastatic pancreatic cancer. Considering the limited efficacy and toxic side effects of chemotherapy, targeted and immune drugs have gradually attracted attention and made some progress. In this article, we systematically reviewed the chemotherapeutic drugs, targets and related targeted drugs, and immunotherapy drugs for pancreatic cancer.

Research progress of tumor immune and tumor metabolic drug targets / 药学学报

The occurrence and development of tumors are closely related to the tumor microenvironment. Among them, tumor immune microenvironment and tumor metabolic microenvironment play important roles in tumor. Tumor immunotherapy is a way to kill tumor cells by activating the body's immune system. Tumor immunotherapy has shown good therapeutic effects in a variety of solid tumors. In recent years, significant progress has been made in tumor immunotherapy. The Warburg effect indicates that tumor cells use aerobic glycolysis to acquire energy. In the tumor, the energy metabolism pathway is abnormal, and the tumor microenvironment can induce the reprogramming of tumor cell metabolism. Therefore, targeting tumor metabolism is also of great significance for tumor treatment. In this paper, we reviewed the research progress of drug targets related to tumor immunology and tumor metabolism in recent years, as well as the progress of drug development.
