While in these studies, proteins or peptides fused with Hsp70 used for immunizations in mice were shown to generate humoral or cellular immune responses, we expect that fusion of anti-MSLN scFv and MTBHsp70 takes advantage of the immune-activating action of MTBHsp70 and the tumor-targeting activity of the scFv, which will yield anti-tumor responses against the broadest profile of tumor antigens. This evidence concerns the gene MSLN and neoplasm.
