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
