This analysis found the expression of several potent NFκB activating cytokines in microglia, including interleukin-1β (IL-1β), TNF-α, and TNFSF8, with the corresponding receptors being expressed in tumor cells (Fig. 1b, g, Supplementary Fig. 3, and Supplementary Data 3). This evidence concerns the gene NFKB1 and neoplasm.
