Purified protein derivative (PPD) (a soluble protein from tubercle bacilli), when injected together with sarcoma cells into syngeneic mice that had been immunized previously with Bacillus Calmitte-Guérin (BCG), prevents tumour toxic to sarcoma cells . However, non-adherent mononuclear peritoneal exudate cells from BCG-treated mice were also found on addition of PPD to become cytotoxic to sarcoma cells. In vivo assays indicate that such cells may play a major role in the in vivo destruction of tumours at the site of a delayed hypersensitivity reaction.
