We conclude that methods based on the use of SV40 T antigen can successfully immortalize human astrocytes, retaining key astrocyte functions, but T antigen-induced proliferation appeared to interfere with expression of glial fibrillary acidic protein. Astrocytes are the most abundant cell types in mammalian brains, within which they participate in various neuronal activities, partly by utilizing the numerous transporters expressed at their plasma membranes. Therefore, we co-cultured exosomes of non-small cell lung cancer (NSCLC) cell line H1299 with human astrocytes to explore their effects on astrocytes and reveal the role of lung cancer cell-derived exosomes on the formation of brain PMN.
