Membrane-anchored chemokine fusion proteins A novel class of adjuvants for immunotherapy

Adoptive or active cancer immunotherapy can fail owing to the inefficient recruitment of effector leukocytes to malignant lesions. The intratumoral injection of recombinant proteins comprising a chemokine-derived domain linked to the mucin stalk of chemokine (C-X3-C motif) ligand 1 (CX3CL1) and a glycosylphosphatidylinositol anchor can specifically enhance the recruitment of effector cell subsets to solid tumors.
