Tumor-derived antioxidants suppress immunity by depriving T cells of reactive oxygen species | Science
Every tool is neither good nor evil in itself. It's only determined by how we use it.
We're used to thinking of reactive oxygen species (ROS) as dangerous and harmful to cells: they directly damage DNA, causing mutations, and disrupt proteins, supporting signaling pathways that can contribute to cancer development. But even this "absolute evil" has a silver lining: ROS are found to be involved in T cell activation, thereby helping the immune system attack tumors. This paradoxical role of ROS is described in the new issue of Science. ROS oxidize certain phosphatases in T cells, shutting them down, and suppressing phosphatase activity is necessary for T cell activation.
Remarkably, tumors have a mechanism that interferes with this pathway of T cell activation. They release the antioxidant peroxiredoxin 1 into the intercellular space, which prevents ROS from supporting T-cell activation after contact with tumor cells.#cell-biology #biology #science #immunology
