We obtained data from previously published studies (Table 2) that measured the expression response of macrophages infected with Mycobacterium Tuberculosis (MTB) (Giraud‐Gatineau et al, 2020), Listeria monocytogenes (Pai et al, 2016), Salmonella Typhimurium (Pai et al, 2016; Alasoo et al, 2018), stimulation with IFN‐γ (Alasoo et al, 2018) and a study that compared tumour associated macrophages with tissue‐resident macrophages from breast cancer tissue (Cassetta et al, 2019). This evidence concerns the gene IFNG and breast cancer.
