“While remaining innocuous to the normal tissues, the prodrug is converted to the cytotoxin by the enzyme localised at the tumour.”

“The gold standard for the diagnosis of C. difficile-mediated disease is a cytotoxin assay.”

“A study has demonstrated that cytotoxin production was the most common virulence factor compared to adhesive and invasive ability.”

“The initial photooxidative injury triggers a number of responses, including direct cytotoxicity within the tumor microenvironment.”

“In vitro, these peptides inhibited cytotoxicity and differentiation of cytotoxic T cells.”

“All the three proteoglycans stimulated mice thymocyte and splenocyte proliferation and elevated cell cytotoxicity.”

“These anti-cancer drugs are actually cytotoxins, or ' cell-killing drugs ' which do not differentiate between good and bad cells.”

“One cell line responded to genotoxins and the other cell line responded to cytotoxins.”

“Apoptosis can be induced by immune cells and cytotoxins, and by changes in homeostatic signals.”
