Research advances on the tumor microenvironment and new immunotherapy strategies for medulloblastoma
Medulloblastoma(MB)is the most common pediatric brain malignancy,with a 5-year overall survival(OS)rate of around 70%.In recent years,the role of the tumor microenvironment on tumor growth has attracted extensive attention.The interaction between tumor cells and other cells in the tumor microenvironment including tumor-associated macrophages(TAM),T cells,NK cells,B cells,and tumor-associated astrocytes(TAA)plays an important role in the onset and progres-sion of MB.Understanding the tumor immune microenvironment of this tumor,especially the relationship between tumor and immune cells,is crucial for the effective development of immune-based therapeutic strategies for MB.This review summarizes the latest research progress on the tumor microenvironment and immunotherapy of MB.
