Revolutionizing Cancer Treatment: The Rise of bacterial ”Trojan Horses”
in a groundbreaking progress that sounds like it’s straight out of a science fiction novel, scientists have unveiled a revolutionary method to treat cancer using bacteria as “Trojan horses” packed with anti-cancer drugs. This innovative approach, detailed in the journal Molecular Therapy, promises to be safer and more effective than customary chemotherapy, which often damages healthy cells alongside malignant ones.
How It Works
The process involves placing specially engineered bacteria onto tumor cells. once inside the malignant cells, the bacteria die, releasing the drugs and killing the tumor from within. This targeted method minimizes harm to healthy tissues, offering a meaningful advantage over conventional treatments.
A Decade of Research
The development of this therapy spanned 10 years, with successful trials in animals for liver, ovarian, and metastatic breast cancers. Researchers are now preparing for human trials, marking a critical step toward bringing this treatment to patients.
Engineering the Perfect Bacteria
Creating a safe and effective bacterium was no small feat. scientists started with salmonella and genetically modified it to ensure it would specifically target and enter malignant cells, rather than lingering in the tumor’s surrounding tissue.
The Role of Flagella and Aspirin
A key revelation was the role of flagella—hair-like structures that help bacteria move.These flagella also aid in penetrating cancer cells. To control this process, researchers devised a clever mechanism: using aspirin to activate the flagella.Without aspirin, the bacteria remain dormant in the tumor. But once the patient takes an aspirin tablet, the bacteria “wake up” and begin their work.
A Simple Yet Powerful Solution
Lead researcher Vishnu Raman from the University of Massachusetts emphasizes the simplicity of the approach: “We wanted to make the treatment as simple as possible. So that the patient can get the drug in, and at home three days later (this is the time needed for the bacteria to colonize the tumor) taking an aspirin tablet.”
The Future of Cancer Treatment
This method holds promise for treating a variety of tumors. While human trials are complex and typically involve patients in advanced stages of cancer, the potential for this therapy to transform oncology is immense.
