“…Many bacteria, like Staphylococcus aureus, naturally produce several chemokine/adhesion receptor inhibitors, which actions avoid cancer cell migration. Staphylococcal superantigenslike (SSL) molecules, such as SSL10 and SSL5, showed to bind specific receptors displayed by cervical and leukemia cells, inhibiting their ability to spread through other tissues in the body (Walenkamp et al, 2009;Walenkamp et al, 2010). Finally, cancer treatment can also be done using live, attenuated or engineered bacteria.…”
