Patients with low NDRG1 expression showed increased CD8+ T cell infiltration and responded better to immunotherapy, whereas patients with high NDRG1 expression exhibited reduced CD8+ T cell infiltration, increased numbers of CD163+ macrophages, and elevated PD‐L1 expression, indicating a stronger immunosuppressive tumor microenvironment (Figure 7H). Here, NDRG1 is linked to neoplasm.
