CCL5 and neoplasm: Here we show that not only are the components of the antigen processing pathway (H2-K1, β2 m) elevated in IL-33 expressing tumours, but also are a variety of chemoattractants (CCL5, CXCL10, CXCL12) that coordinate the transportation of the innate and adaptive immune cells to the tumour site, whereas the production of immunosuppressive factors (IL-10, Ptgs2) is reduced.
