Breaking: Doctors Can Now Use Light to Fight Cancer!

Doctors have discovered an exciting therapy of new non-evasive light that can help the body's own cells to fight cancer! Supporting our own bodies in the fight against the disease, also known as immunotherapy, is one of the most popular and growing of cancer research. Let's face it, people are tired of chemotherapy and surgeries rather avoid dangerous if they can help. Now, with these new therapies and new technology of light that can boost the body without damaging it.

Zhou Yubin assistant professor, Ph.D. Research Center of Translational Cancer located in the Texas A & M University Health Science Center Institute of Biosciences and Technology is actively studying how light can be used to control the immune system of our body and use it to fight cancer.


"Although neuroscientists have been using light to stimulate neurons for years, this is the first time the technique, called optogenetics, has been used in the immune system, "Zhou said.


Typically, in neuroscience, scientists to design cells producing microbes are sensitive to the light. When different frequencies of light exposed these microbes produce proteins that can show our nerves to send or stop sending nerve impulses.

"Neuroscientists have learned a lot about the brain circuits that use the technique" Zhou said, "and now researchers in many other fields is given a test."

Optogenetics and immune system

Zhou and his team have found a way to modify the technique in order to help the immune system. The work was not easy: Unlike nerve cells, cells of the immune system not known to communicate using electrical impulses. Another challenge is that our immune system cells are deep within the body and are constantly moving around making it difficult to hit with the right amount of light.

had to use a little outside the box thinking and teamwork to figure out.

"We have collaborated with Dr. Gang, Han at the University of Massachusetts Medical School and photomedicine makes bionanotechnologies development," Zhou said. "Together, we have been able to combine the state of optogenetics technique on the cutting edge of nanotechnology." .

The new nanotechnology known as the optogenetic immunomodulation has recently been published in an article in eLife

"This work was conducted by talented scientists in the laboratory graduate students Lian He and Peng Tan and postdoctoral Guolin researcher Ma, Ph.D., "said Zhou," fearlessly carried out this project and overcame daunting obstacles all difficult to make this technique really. "

doctors can use the light to the cells of the immune system

with this new technique, the researchers were able to control cells of the immune system and 'instruct' to kill cancerous tumor cells. Using a laser beam in the near infrared that is able to penetrate a few centimeters into the body scientists can use nanoparticles to turn blue and directing immune cells engineered to combat specific cancer cells. Imagine a general and his


Imagine a general and his troops about to go into battle, and once they get the signal bright central command that bind to and destroy cancer cells.

"We are able to wirelessly control the action of immune cells buried deep in the tissue," Zhou said.

Researchers found a way to modify the immune system cells so that its calcium-controlling proteins door was sensitive to light. When they exposed to blue light, which is emitted by the nanoparticle 'open doors ion'. Once the doors light then close off. Researchers can increase the flow of calcium into cells by increasing the flow of light.

They are still working on the set-dependent actions calcium immune cells so they can better target tumor cells and invasion of pathogens that our body otherwise would not notice or focus on the fight.

When evidence of tumor animals were able to stimulate the immune system response that helped in were made body's ability to kill cancer cells.

"the technique reduces the size of the tumor and metastasis, so there are a lot of applications," Zhou said.

One of the biggest advantages of this method is that only activate a specific type of cell in the immune system, T cells, and only in the area of ​​the body where the light is shone. Upon arriving chemotherapy the immune system throughout the body, which can be a miserable process. With this technique adjustable light non-invasive, which can focus the immune response only in and around the area of ​​concern.

"Other scientists are likely to use the technique to help them study immune, heart and other types of cells using calcium to perform their tasks, "Zhou said. "It's quite a cool technology. With these tools, we can now not only answer fundamental questions of science that we never could before, but also translate into the clinic for disease intervention."

lab Zhou has been using this technique in order to see how drugs effective specific cancers even have on people.

"If successful," said Zhou, "all these efforts significantly improve existing immunotherapies against cancer by customizing the treatment to exactly where and when needed, while reducing side effects. "
