Russian scientists revealed new scientific research that holds hope For millions Patients around the world learned about a revolutionary cancer treatment technology that relies on lasers to control immune cells and direct them to destroy tumors with extreme precision, without harming healthy tissues, according to what was published in news.cn.
Smart medicine that works by direct command
ITMO University in St. Petersburg announced the success of its researchers in developing a therapeutic system based on light-sensitive microcapsules. The idea of this innovation is similar to smart capsules that are injected into the body, but they remain completely ineffective until they receive an order to work. This command comes through a laser beam that doctors direct precisely at the tumor, so the capsules open and release the immune-modulating drug at the exact place and time.
Goodbye side effects
Regarding the secret of this innovation, Lydia Mikhailova, a researcher at the university’s Faculty of Physics, says: We have proven in our study the ability to control remotely the moment treatment begins, and the biggest advantage here is accuracy. The medicine only works when we shine a laser, which means protecting healthy tissues from any damage and reducing stressful side effects for the patient.
Detecting the malignant tumor trick
Scientists have discovered that cancerous tumors do not depend only on their genetic mutations, but rather deceive the surrounding immune cells called macrophages, reprogramming them to become guardians of the tumor instead of attacking it.
