產(chǎn)品:重組人腫瘤壞死因子-αVariant
貨號(hào):103-01V
Description | The clinical use of the potent antitumor activity of TNF-α has been limited by the proinflammatory side effects including fever, dose-limiting hypotension, hepatotoxicity, intravascular thrombosis, and hemorrhage. Designing clinically applicable TNF-α mutants with low systemic toxicity has been an intense pharmacological interest. Human TNF-α, which binds to the murine TNF-α55 but not to the murine TNF-α75, exhibits retained antitumor activity and reduced systemic toxicity in mice compared with murine TNF-α, which binds to both murine TNF receptors. Based on these results, many TNF-α mutants that selectively bind to TNF-α55 have been designed. These mutants displayed cytotoxic activities on tumor cell lines in vitro, and exhibited lower systemic toxicity in vivo. |
