RESUMEN
Aim To explore the effect of total salvianolic acid (TSA) combined with anti-PD-Ll on the development of breast cancer by inhibiting the infiltration of myelogenous macrophages into tumors. Methods E0771 breast cancer subeutaneous tumor model was constructed. Twenty-five mice were randomly divided into control group, model group, total salvianolic acid group (TSA 10 g • kg
RESUMEN
Pericytes are essential components of vessel mural cells that function to regulate blood flow, clear or phagocytose debris, and are contractile cells enwrapping capillaries throughout the body. It controls vascular permeability and is involved in the development of blood vessels and is an important regulator and potential drug target of angiogenesis and vascular function. Pericytes are also thought to play a key role in the tumor microenvironment, especially during tumor growth and distal metastasis. Therefore,in this review we discuss the relationship between pericytes involved in tumor angiogenesis and tumor metastasis, as well as the use of targeted pericytes to treat tumors,with a view to providing a basis for subsequent studies.
RESUMEN
In the tumor microenvironment, tumor cells and nerv e eells infiltrate each other, ultimately promoting the occurrence and development of tumor.Numerous evidence shows that neuro-genesis plays a key role in the regulation of tumor microenviron¬ment.By reviewing the interaction between neurogenesis and tumor and tumor microenvironment.this paper summarizes the factors including nerve growth factor that affects neurogenesis mediated tumor proliferation and metastasis, and the significance of tumor detection and treatment by regulating nerve signal.'Hie purpose of this study is to assist clinical treatment of tumor pro¬liferation and metastasis from the perspective of neurogenesis.
