Optogenetic Immunomodulation Reduces Cancer Tumor Size, Metastasis in Animal Model

Facebook X LinkedIn Email
Optogenetics has been modified for an immunotherapeutic approach that aims to kill cancerous tumor cells. Neuroscientists have used light to stimulate neurons for years, said professor Yubin Zhou of Texas A&M University’s Health Science Center Institute of Biosciences & Technology. In neuroscience, optogenetics involves genetically engineering cells to produce proteins from light-sensitive microbes. The result is nerve cells that either send or stop sending nerve impulses when exposed to a particular wavelength of light. Unlike nerve cells, immune cells don't...Read full article

    optogenetics
    A discipline that combines optics and genetics to enable the use of light to stimulate and control cells in living tissue, typically neurons, which have been genetically modified to respond to light. Only the cells that have been modified to include light-sensitive proteins will be under control of the light. The ability to selectively target cells gives researchers precise control. Using light to control the excitation, inhibition and signaling pathways of specific cells or groups of...
    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
