Of the genes that participate in the immune response, 61 were found to be downregulated in infected animals, such as the CCL20 gene, which is responsible for chemotaxis in dendritic cells (DC), effector/memory T-cells, and B-cells and plays an important role on skin and mucosal surfaces under homeostatic and inflammatory conditions, as well as in pathogenesis, including that of cancer and autoimmune diseases. Here, CCL20 is linked to cancer.
