Lingyun Ye and Yinfei Wu contributed equally to this work. Previous studies have found that prior to metastasis, the primary tumor can reshape the microenvironment in a specific tissue and induce the formation of a pre-metastatic niche (PMN), which offers a valuable opportunity for the adaptation and survival of the primary tumor cells, enabling them to proliferate and obtain conditions for colonization in the target organ for subsequent metastasis [16].

As an essential component of BBB, astrocytes are indispensable in the immune microenvironment for brain metastasis of lung cancer. WebAstrocytes are the most abundant cells in the central nervous system where they perform many functions, such as providing mechanical support and nutrients to neurons and Tumor cell-derived exosomes usually carry important signal molecules, such as miRNA, which can reshape the tumor microenvironment by regulating immune response and angiogenesis, thus participating in the metastasis of tumor cells [13]. CD9, CD63, HSP90, and Alix were used as exosome-positive protein markers, and Calnexin as an exosome-negative protein marker.
