In this eosinophil-mediated anti-tumor response, CCL11, an eosinophil-selective chemokine in the ‘eotaxin subfamily,’ was demonstrated to be cleaved by DPP4 into a truncated form (CCL113–74) with diminished chemoattractant properties [69], as found for CXCL10 cleavage by DPP4. The gene discussed is DPP4; the disease is neoplasm.
