Myeloid cells were extracted and analysed for function using GSEA, which revealed that their functions were mainly enriched in the extracellular matrix, antigen immune presentation, activation of the immune system (innate/acquired), cytokine secretion, interferon signalling and other functions, suggesting that IL-1 signalling promotes antigen presentation and thus enhances tumour immunity, in agreement with the bulk transcriptome results. The gene discussed is IL1B; the disease is neoplasm.
