The microenvironment of the invasive margin of @liver metastases.
There was no relevant Th1, Th2, or Th17 #cytokine signature present in any of the samples. However, the authors did find that @chemokine s and @macrophage -related cytokines were significantly increased at the invasive margin. Chemokines are molecules that help to attract @immune cells to the area, and macrophage-related cytokines are molecules that help to regulate the activity of #macrophages, which are a type of immune cell.
