To validate the finding that macrophages are reeducated towards an M1‐like polarisation in tumours treated with PI3K/mTORi and PI3K/mTORi+PD‐1i, we evaluated the expression of M1 (CD86) and M2 (CD163, CD206) markers on FFPE tissue sections from humanized EMC041 PDX tumours collected at sacrifice, using MILAN‐analysis (Figure 5H). The gene discussed is CD86; the disease is neoplasm.
