Two studies showed that cytokines like tumor necrosis factor alpha (TNFα), Interleukin (IL)-1 and interferon gamma (IFNγ) induce neutrophil adhesion to SK-N-SH and LAN-1 neuroblastoma cell lines by upregulating intercellular adhesion molecule-1 (ICAM-1) expression [42, 43]. This evidence concerns the gene ICAM1 and neuroblastoma.
