Abstract:

Cholera toxin is an AB5-type toxin secreted by vibrio cholerae and has the ability to regulate immunity. Research has found that cholera toxin has potential anti-cancer effects. It not only inhibits cell proliferation by suppressing growth factor signaling or triggering apoptosis, but also acts as an immunomodulator by mediating inflammatory responses and regulating the immune system to inhibit tumor occurrence and development. Additionally, cholera toxin can also indirectly exert anti-tumor effects by assisting in targeted drug delivery and serving as an adjuvant in vaccines. This article reviews the role of cholera toxin in tumors, providing new ideas for cancer prevention and treatment.

Key words: cholera toxin, neoplasms, adjuvants, immunologic, vaccines, cell proliferation, immunomodulation
