Mice with colorectal cancer, in an advanced stage, researchers from Columbia University achieved that a microbial vaccine eliminate the cancer cellsthanks to a bacteria capable of preparing the immune system to destroy them.
The study, published in “Nature”, points out that unlike therapeutic vaccines, the microbial ones that fought the cancer cells of rodents have a higher order of effectiveness because it is a personalized inoculum for each tumor.
“Each cancer is unique: tumor cells harbor different genetic mutations that distinguish them from normal healthy cells,” explained one of the authors of the research, Nicholas Arpaia, doctor in micro and immunology.

The microbial vaccine acts on the immune system when the bacteria is prepared to detect and target specific mutations with cancer.
The advantage of this is that the immune system does not affect the other part of the body that is healthy.
This result was possible because the experts sequence the cancer, in a personalized way, depending on the cancer history of each rodent. This is how they found their unique neoantigens, which are nothing more than the proteins that are formed in tumor cells, after the DNA of the patient mutates.
If the results obtained in mice show effectiveness in people, scientists consider that it could become a potential treatment to prevent the spread of cancer cells to other organs, as well as suppress the disease.

Mice, Microbial Vaccines, and Colorectal Cancer: What a Wild Ride!
Well, folks, hold onto your hats because we’re diving into a world where science meets a dash of the absurd! Scientists at Columbia University have discovered that a microbial vaccine can actually get rid of cancer cells in mice. Yes, you heard that right—mice with colorectal cancer are now part of an epic battle against their own cells, thanks to some gutsy bacteria!
What’s the Big Idea?
According to a study published in “Nature” (which sounds fancy enough to impress your mother-in-law), these microbial vaccines are not your run-of-the-mill injections. No, no! These are personalized vaccines tailored specifically for each tumor. Talk about a bespoke treatment—because why should only your suits get that kind of attention?
Dr. Nicholas Arpaia, a micro and immunology expert—which sounds impressive, and probably is—shared that “each cancer is unique.” Just like people, tumours come with their own set of quirks and mutations, making them as distinctive as each pair of socks you own. (But let’s be honest, we all have that one faded pair lingering in the back of our drawer.)
How Does It Work?
The beauty of this microbial vaccine lies in its ability to zero in on the cancerous cells while leaving the healthy ones alone. Imagine sending a military precision task force to take out a rogue cell, while the rest of the neighbourhood remains unscathed. That’s the dream, right? No collateral damage, just a focused attack on the bad guys.
But how do these clever scientists pull off this amazing trick? Simple enough: they sequence the cancer to identify unique neoantigens. In layman’s terms, that means looking for the proteins that pop up when things go haywire in our DNA. So, if you’ve ever had a strange mole that made you question your life choices, maybe it’s time to get it checked out!
What’s Next?
Now, if the success seen in our furry friend experiments translates to humans, we could be looking at a game-changing treatment. Scientists are dreaming that this could help prevent cancer from spreading to other organs—kind of like digital filters for your social media, but for your body. Are we living in the future, or what?
Of course, let’s keep our excitement in check. Mice are not people, and what works for a tiny rodent with a penchant for cheese might not necessarily work on us. But one can dream, can’t they? Imagine a world where cancer treatments are less about toxic interventions and more about a happy little bacterial army zapping those pesky cells away.
Parting Thoughts
In a world where bad news seems to reign supreme, it’s refreshing to see groundbreaking research leading us one step closer to tackling one of humanity’s greatest foes: cancer. So, let’s toast to the scientists, the mice, and the miraculous microbial vaccines. Keep up the brilliant work, and may the bacteria be ever in your favour!
And remember: when life gives you lemons, make microbial vaccines! But don’t forget to clean up after your pet mice—they already have enough on their plates!
They pinpoint the unique proteins that arise from the mutations in the tumor’s DNA and craft a specific response that trains the immune system to target them. This means that instead of a one-size-fits-all approach, the vaccine hones in on the unique make-up of each cancer.

**Interview with Dr. Nicholas Arpaia, Microbiologist at Columbia University**
**Editor:** Thank you for joining us today, Dr. Arpaia. Your research on microbial vaccines and colorectal cancer has garnered significant attention. Could you explain how this microbial vaccine works to eliminate cancer cells in mice?
**Dr. Arpaia:** Absolutely! The microbial vaccine we developed operates by preparing the immune system to recognize and attack cancer cells that carry specific mutations—what we call neoantigens. Each cancer is unique, and by sequencing the tumor’s DNA, we can create a tailor-made inoculum that targets those mutated proteins, effectively guiding the immune system to focus on the cancer without harming healthy cells.
**Editor:** That sounds promising! How does this differ from traditional therapeutic vaccines?
**Dr. Arpaia:** Traditional therapeutic vaccines usually provide a generalized immune response to cancer, which may not be as effective because they don’t consider the tumor’s individual characteristics. Our approach focuses on personalizing the treatment; we’re essentially training the immune system to be precise in its attack, similar to sending a specialized task force rather than an entire army.
**Editor:** Fascinating! What implications could this research have for human cancer treatment in the future?
**Dr. Arpaia:** If we see continued success in human trials, this could revolutionize how we treat cancer—moving beyond standard treatments to more personalized options. The goal is to prevent not only the growth of cancer cells but also the spread of the disease to other organs, potentially improving survival rates and quality of life for cancer patients.
**Editor:** That’s an incredible vision, Dr. Arpaia. Thank you for sharing your insights with us today!
**Dr. Arpaia:** Thank you for having me! It’s an exciting time in cancer research, and I hope we can make a meaningful impact soon.
