  "account": "Scientists at Rockefeller University have found that antibodies called immunoglobulin A (IgA), which coat the lining of the gut, may play a crucial role in preventing colon cancer. Mice lacking IgA developed more than twice as many colon tumors as usual, according to a study published in Nature. IgA binds to the cells lining the gut, preventing them from dividing too quickly, which could lead to cancer. When researchers gave IgA-deficient mice oral doses of the antibodies, the mice no longer had a higher risk of developing tumors. The discovery could provide insights into how the gut's immune system and microbes interact, potentially leading to new interventions to reduce colon cancer risk.",
