A team of researchers has developed an ultrasound-based system that can non-invasively and remotely control genetic processes in live immune T cells so that they recognize and kill cancer cells.
There is a critical need to non-invasively and remotely manipulate cells at a distance, particularly for translational applications in animals and humans, researchers said.
The team developed an innovative approach to use mechanogenetics—a field of science that focuses on how physical forces and changes in the mechanical properties of cells and tissues influence gene expression—for the remote control of gene and cell activations. Researchers used ultrasound to mechanically perturb T cells, and then converted the mechanical signals into genetic control of cells… Continue reading.
San Diego, Calif., Sept. 28, 2017 — A team of researchers has engineered smart protein molecules that can reprogram white blood cells to ignore a self-defense signaling mechanism that cancer cells use to survive and spread in the body. Researchers say the advance could lead to a new method of re-engineering immune cells to fight cancer and infectious diseases. The team successfully tested this method in a live cell culture system.
The work was led by bioengineering professors Peter Yingxiao Wang and Shu Chien with collaborating professors Victor Nizet and Xiangdong Xu, all at the University of California San Diego, along with researchers from the University of Illinois at Urbana-Champaign. The team published their work this month in Nature Communications.
The smart proteins, called “iSNAPS” (integrated sensing and activating proteins), are designed to detect precise molecular signals in live cells and in response, act upon those signals to enable the cells to fight disease or perform other beneficial functions. This study is the first to demonstrate how both sensing and activating capabilities can be combined into a single molecule, Wang said.
The researchers inserted their iSNAPS into a type of white blood cells called macrophages and demonstrated that they dramatically enhanced the macrophages’ ability to engulf and destroy rapidly dividing cancer cells… Continue reading.
Bioengineers at UC San Diego have helped us understand why atherosclerosis develops and how it is impacted by blood flow. They have pioneered the development of very thin, small and flexible sensors that stick to the skin and monitor vital signs, such as the brain activity of a newborn. They also developed injectable hydrogels that can help muscle tissues heal after a heart attack.
Researchers celebrated their achievements over the past five decades and looked to the future during a three-day 50th anniversary celebration May 19 to 21.
“This department was created in the same spirit as our campus, as an innovative, collaborative and experimental place,” said Chancellor Pradeep K. Khosla during an anniversary gala at the Birch Aquarium. “We are proud that UC San Diego’s Bioengineering Department has been a leader in the field since its founding, advancing our mission of education, research and service.”
A team led by engineers at the University of California, San Diego has 3D-printed a tissue that closely mimics the human liver’s sophisticated structure and function. The new model could be used for patient-specific drug screening and disease modeling. The work was published the week of Feb. 8 in the online early edition of Proceedings of the National Academy of Sciences.
Researchers said the advance could help pharmaceutical companies save time and money when developing new drugs.
“It typically takes about 12 years and $1.8 billion to produce one FDA-approved drug,” said Shaochen Chen, NanoEngineering professor at the UC San Diego Jacobs School of Engineering. “That’s because over 90 percent of drugs don’t pass animal tests or human clinical trials. We’ve made a tool that pharmaceutical companies could use to do pilot studies on their new drugs, and they won’t have to wait until animal or human trials to test a drug’s safety and efficacy on patients. This would let them focus on the most promising drug candidates earlier on in the process.”
Chen and Shu Chien, a professor of Medicine and Bioengineering, director of the Institute of Engineering in Medicine at UC San Diego and recipient of a National Medal of Science, are co-senior authors of the study.
Two researchers at the University of California, San Diego, have been named fellows of the National Academy of Inventors.
Shu Chien, Distinguished Professor of Bioengineering and Medicine, and Michael Sailor, Distinguished Professor of Chemistry and Biochemistry, were among 168 new fellows announced by the academy today.. … Read the full story from the UC San Diego Newsroom

Six University of California, San Diego professors have been named Fellows of the American Association for the Advancement of Science (AAAS), the world’s largest general scientific society. They are among 347 members selected this year by colleagues in their disciplines to be honored for “scientifically or socially distinguished efforts to advance science or its applications.”
Shu Chien, MD, PhD, is a professor of medicine and bioengineering and director of the Institute of Engineering in Medicine at UC San Diego. He was cited for “continuing outstanding contributions to vascular physiology and vascular cell and molecular biology, which have greatly increased our understanding of vascular pathologies including atherosclerosis.” His work, which focuses on the study of how blood flow and pressure affect vessels, earned him a National Medal of Science in 2011. He is one of only 11 scholars in the United States to be a member of all three national academies: Sciences, Engineering and Medicine.
Philadelphia, Nov. 12, 2015 – Shu Chien, founding chair of the Department of Bioengineering at the University of California, where is he currently a professor and director of the Institute of Engineering in Medicine, has received the prestigious Franklin Institute Award.
The award is conferred by the Philadelphia-based Franklin Institute. It has gone in previous years to an extraordinary list of great men and women who have significantly improved our world with their pioneering innovations, including Thomas Edison, Marie Curie, Stephen Hawking, Jacques Cousteau, and more recently Jane Goodall, Dean Kamen and Bill Gates.
“I am extremely honored and humbled by being chosen as a recipient of the Benjamin Franklin Medal, to be in company with all the superb medalists,” Chien told the San Diego Union-Tribune Thursday. “I appreciate particularly that the award is in mechanical engineering, which I learned in my faculty years from my wonderful colleagues and apply to the study of cardiovascular system in health and disease.”
Many of tomorrow’s solutions to today’s challenges in medicine will require feats of engineering in addition to biology, chemistry and health sciences. In fact, inventions such as valve prostheses, vascular stents and heart rhythm control systems are examples of how biology and medicine can work together with engineering to improve processes for maintaining health and quality of life.
This is one of the main messages coming out of an article published April 1 in the journal Science Translational Medicine.
