More recently, researchers have begun to look at conjugating immunomodulatory agents to antibodies to directly activate an immuneresponse against the tumour. This approach – immune-stimulating antibody conjugates (ISACs) – uses a payload that stimulates the innate and adaptive immuneresponses, recruiting tumour-fighting T cells.
