"Experimental drugs being tested in clinical trials for leukaemia may also boost the body’s immune response against other forms of cancer, according to research from University College London (UCL).
"The drugs target an important protein called p110δ, produced in large amounts in white blood cells called ‘leukocytes’.
"Leukaemias can develop if leukocytes become cancerous, making p110δ a promising target for treating this form of cancer.
"And recent clinical trials using these drugs have shown encouraging results. But until now the potential benefit of these drugs for other types of cancer had remained unexplored.
"In the latest study, published in Nature, researchers working with mice bearing solid tumours found that the drugs - called p110δ inhibitors - helped boost their immune response against a range of tumour types – including breast cancer."
Editor's note: Scientists have tested new drugs in mice with a variety of tumor types, including breast cancer, and found that the drugs may help the mice fight off cancer. These drugs are already being used in humans in clinical trials for leukemia, so it might not be long before scientists try the drugs in volunteer patients with other types of cancer.
