The present invention relates to compositions and methods that provide novel anti-tumor therapies in cancer. In one aspect, the present invention features a hybrid neutrophil in a non-naturally occurring container, wherein the hybrid neutrophil expresses at least one neutrophil associated molecule selected from the group consisting of: Arg1, MPO, CD66b, and CD15, and at least one antigen-presenting cell (APC) associated molecule selected from the group consisting of: CD14, HLA-DR, CD32, CD64, and CD89. In another aspect, the present invention features methods of generating a hybrid neutrophil. In still another aspect, the present invention features methods of inhibiting tumor growth in a subject, treating a tumor in a subject, and increasing efficacy of an antibody against a tumor in a subject. The methods comprise (a) administering to the subject an effective amount of an anti-tumor antibody and (b) administering to or generating in the subject an effective amount of a hybrid neutrophil. |
