Novel therapeutic approach against Epstein-Barr virus-associated tumors — ScienceDaily

A research team at LKS Faculty of Medicine, The University of Hong Kong (HKUMed) discovered that exosomes derived from V?2-T cells (Vδ2-T-Exos) can effectively control Epstein-Barr virus-associated tumours and induce T-cell anti-tumour immunity. The novel findings of Vδ2-T-Exos provide insights into new therapeutic approach for Epstein-Barr virus (EBV)-associated tumours. The ground-breaking findings have been published in the leading academic journal, Science Translational Medicine.

EBV infects about 95% of the human population and causes more than 200,000 cases of cancer each year and that around 2% of all cancer deaths are due to EBV-attributable malignancies. EBV-associated tumours include Burkitt lymphoma, Hodgkin lymphoma, nasopharyngeal carcinoma, gastric tumour and post-transplant lymphoproliferative disease, etc. Current treatment options for EBV-associated tumours are limited with considerably unwanted off-target toxicities and incomplete effectiveness for relapsed or refractory disease. V?2-T cells are innate-like T cells with anti-tumour potentials against EBV-associated tumours. Unfortunately, its clinical translation is limited

Antimatter Particles Hold Key In Timely Attack Against Growing Tumors

KEY POINTS

  • A timer invented by experts permits PET scanners to attack  cancer cells in their weakest
  • The invention may pave the way to less invasive radiation treatment for cancer patients
  • Inventors hoped the technology can be made more affordable in a decade

Doctors may soon kill cancer tumors with less invasive side effects of radiation treatment. This is after a team of experts designed a scanner that can time the antimatter particles that are significant in detecting the levels of the oxygen concentration in cancer tissues. For years, medical experts have witnessed how low levels of oxygen prevented the timely killing of rapidly growing cancer cells. 

A team of Japanese atomic physicists and nuclear medicine experts designed a timer that can detect the oxygen concentration of tissues growing throughout ta cancer patient’s body. Specifically, the timer permits the positron emission tomography (PET) scanners to know when to attack the

Team aims to detect oxygen concentration in tumors using upgraded medical imaging scan — ScienceDaily

Experts in Japan have devised a simple way to glean more detailed information out of standard medical imaging scans. A research team made up of atomic physicists and nuclear medicine experts at the University of Tokyo and the National Institute of Radiological Sciences (NIRS) has designed a timer that can enable positron emission tomography (PET) scanners to detect the oxygen concentration of tissues throughout patients’ bodies. This upgrade to PET scanners may lead to a future of better cancer treatment by quickly identifying parts of tumors with more aggressive cell growth.

“Patients’ experience in this future PET scan will be the same as now. Medical teams’ experience of conducting the scan will also be the same, just with more useful information at the end,” said nuclear medicine physician Dr. Miwako Takahashi from the NIRS, a co-author of the research publication in Communication Physics.

“This was a quick project for
