Researchers at Colombia University have developed probiotic bacteria that can train the immune system to eliminate cancer cells. Taking advantage of bacteria's innate tumour-targeting capabilities, the researchers developed this unique vaccine against cancer. Notably, these bacteria can be trained according to each person's unique cancer, tumour, and metastases. Cancer Vaccine Was Tested On Mice This innovative bacterial vaccine was tested on mice with advanced colorectal cancer and melanoma. The researchers found that it stimulated their immune system, causing primary and metastatic malignancies to shrink or in many cases disappear entirely. All this while leaving the healthy body parts unaffected. Notably, this bacterial vaccine proved to be particularly effective than the peptide-based therapeutic cancer vaccines that were previously used in trials. "The important advantage of our system is its unique ability to coordinately restructure and activate all arms of the immune system to induce a productive antitumor immune response, said Andrew Redenti, a student at Colombia University and one of the rsearchers in the study. The study has been published in the journal Nature. Role Of Bacteria In Cancer TreatmentBacteria have been used for cancer treatment since the late 19th century. Today, they are employed as therapeutic in patients with early-stage bladder cancer. Meanwhile, recent research has indicated that there are certain bacteria which naturally migrate and even colonised tumours.Here's how you can cultivate good bacteria in your body:Probiotics are live microorganisms (microbes) that can have beneficial effects on or inside your body. Every human body is home to trillions of microorganisms that live with us and help support our bodily functions and health. You can follow the below-mentioned steps to cultivate them in your body. Start by keeping a diverse and balanced diet. Include a variety of fruits, vegetables, whole grains, and legumes to provide different nutrients that support diverse microbial growth.Incorporate fermented foods into your diet. Consume foods like yoghurt, kefir, sauerkraut, kimchi, and kombucha, which are rich in probiotics that help boost beneficial gut bacteria.Reduce intake of sugar, artificial sweeteners, and highly processed foods, which can negatively affect the gut microbiome. You should also try and minimise your consumption of junk food. Drink plenty of water to support digestion and help maintain a healthy balance of microbes in the gut.Engage in regular physical activity and exercise. This will positively influence gut health and promote the growth of beneficial microbes.
