Prior to this study, it remained unclear if the cytotoxic effects of IMMUNEPOTENT CRP were attributed to its exosomes or its different components obtained by centrifugation (supernatant or pellet) because the cytotoxic test on 4T1 breast cancer cell lines revealed that exosomes are not the main bioactive in charge of the cytotoxic effect on cancer cells. The gene discussed is CRP; the disease is cancer.
