We and others have shown previously that microglia show direct cellular interactions with tumour cells and pre-neoplastic AKT1+ cells in the brain (Bayerl et al., 2016; Hamilton et al., 2016; Resende et al., 2016; Ricard et al., 2016; Chia et al., 2018). The gene discussed is AKT1; the disease is neoplasm.
