Researchers at the Weizmann Institute of Science have found a new natural “weapon” that could help fight cancer, reports The Jerusalem Post.
These weapons are naturally produced antibodies that neutralize certain threats. Recent studies have shown that antibodies were often found in cancerous tumors, but their role was unknown: the body could produce them without any relation to cancer.
Indirect evidence suggested that antibodies have some antitumor effect . Patients who live longer than others and respond better to cancer drugs have higher concentrations of antibody-producing B cells in their tumors.
the detected antibodies are the enzyme MMP14. In a healthy person, this enzyme plays an important role in the regeneration or healing of wounds, but in a cancer patient, this enzyme spreads uncontrollably, helping cancer cells to penetrate surrounding tissues and spread to other organs.
Researchers from the Weizmann Institute of Science have found that tumors ovaries in their study contained abnormally high levels of the enzyme MMP14.
“Now we have shown that the immune system of cancer patients can produce antibodies against tumors. These natural antibodies appear to have untapped therapeutic potential,” they said. researchers.
