Biography
I have educational background in Medical Technology, Biochemistry, and Human Genetics. I received a Ph.D. degree in Human Genetics from John Curtin School of Medical Research (JCSMR), Australian National University (ANU), and have been working at the Faculty of Medicine Siriraj Hospital, Mahidol University for 35 years. My research works involved in genetics/genomics and molecular biology studies of human genetic diseases, which I attempted to understand their etiologies and molecular pathogenesis. I have published more than 120 articles in these fields. A part of my research work and publication (about 50 articles) was in the fields of molecular pathogenesis of infectious disease (i.e. dengue virus infection) and virus-host interactions at cellular and sub-cellular levels. These educational and research background pave the way for my current research interest in the field of cellular immunotherapy of cancer, in which the technologies in molecular genetics, biochemistry, molecular biology and cellular biology are applied.
My current research interest in cellular immunotherapy of cancer is focused on the development and evaluation of cytotoxic T cells (CTL) and chimeric antigen receptor (CAR) T cells for cancer therapy. Cancer is the disease that threatens human lives. It is the major cause of death of people in many countries worldwide; it is also the top leading cause of death in Thai people. It has been well known that almost all cancers occur from the accumulation somatic mutations while germline mutations take part only about 8% as the cause of heritable cancers. Our immune system plays crucial role to prevent cancerous cells to grow and spread as they will be detected and eliminated; cancer occurs because the cancerous cells can escape our body immune system. If we can strengthen our immune system, cancer will be prevented. We can also take the patient’s immune cells, especially T cells, to train or engineer them to use as ‘living drug’ for treatment of cancer. Our research group has successfully generated CTL activated by monocyte-derived dendritic cells presenting tumor-associated antigens (TAA) and generated CAR T cells targeting several TAA on cholangiocarcinoma (bile-duct cancer), breast cancer, retinoblastoma (eye cancer), and leukemia. We have reported these results in many recent publications and we are setting up clinical trials to translate these technologies into clinical application and service in our hospital and other hospitals in Thailand and the Southeast Asian region.
