Natural Killer (NK) cells have long been the immune system’s “soldiers” on the battlefield protecting us from infections. NK cells are also in charge of protecting us against the onset, growth, and spread of cancer. However, to avoid being killed, cancer cells can inhibit NK cells.
Australian scientists recently discovered that cancer cells secrete a peptide (short-chain protein) called Activin-A that directly suppresses NK cells. Their groundbreaking research was published in the journal Science Signaling. Activin-A was found to disable the ability of NK cells to stop cancer.
Until now, the exact mechanism that cancer cells use to suppress NK cells has largely remained a mystery. Most importantly, the scientists found that another peptide called follistatin can block Activin-A. Without Activin-A in the picture, NK cells can now attack cancer unimpeded.
Comments from Dr. Thomas: A strong and unhindered immune system is our best defense (and offense) against cancer. I use a potent combination of repurposed medicines, peptides (including follistatin), and natural compounds to help regenerate functional thymus tissue, boost the production of immunocompetent cytotoxic T-cells (CTCs) and NK cells, increase the expression of major histocompatibility complex-1 (MHC-1) and tumor-associated antigens (TAAs), and inhibit the known mechanisms that cancer uses to evade immune attack.
