Cancer has been likened to an "unhealable wound", indicating that the immune system is unable to effectively eliminate invading tumor cells. A research team at the Wilmot Cancer Institute at the University of Rochester Medical Center in the United States has discovered a key molecule that can reprogram immune cells, transforming them into "accomplices" that promote cancer development.
The corresponding author of the study points out that investigating the behavior of these "pro-tumor" immune cells is crucial, as they could serve as therapeutic targets to halt cancer progression. This finding has been published in the Proceedings of the National Academy of Sciences (PNAS).
The research team investigated the dynamic interactions between cells in the tumor environment, uncovering the mechanism by which immune cells shift from resisting cancer to aiding its development.
They found that Platelet-Activating Factor (PAF) is a key molecule that determines the fate of immune cells. PAF not only recruits pro-cancer cells but also inhibits the immune system's anti-cancer capabilities. Various cancers rely on the same PAF signal for spreading.
The researchers emphasize that finding a treatment method to block PAF could potentially be effective for various types of cancer.
