Immune System 'Brake' SLAMF6 Identified in Cancer Treatment Resistance
Scientists have uncovered a mechanism by which certain cancer treatments may lose effectiveness. A molecule named SLAMF6 has been identified as an immune system "brake" that weakens the body's cancer-fighting T cells, leading to their exhaustion over time. Researchers have developed antibodies that block SLAMF6, which in turn allowed immune cells in mice to remain stronger and more effectively combat tumors.
Scientists have identified a previously hidden immune system mechanism that may contribute to how cancers evade destruction. This mechanism involves a molecule designated SLAMF6, which functions as an immune system "brake."
SLAMF6 has been observed to weaken T cells, which are crucial components of the body's immune response against cancer. This weakening can lead to the exhaustion of T cells, reducing their ability to fight off cancerous growths effectively over time.
In response to this discovery, researchers developed specific antibodies designed to block the activity of SLAMF6. Experiments conducted in mice indicated that by blocking this molecular brake, immune cells were able to maintain their strength and more effectively attack tumors.
