CSF3 and astrocytoma (excluding glioblastoma): To further validate cell migration mechanism induced by HIV-1 gp120, we investigated the involvement of monocyte chemo-attractant protein-1 (MCP1) (Figure 3F) and granulocyte colony stimulating factor (GCSF) (Figure 3G) in astrocytoma, since these cytokines are key players in microglia’s migration [43–45].
