Bacterial Cancer Therapy

With gene engineering, we are developing avirulent bacterial strains showing tumor targeting and anticancer activities. Our ultimate goal is engineering of oncolytic bacteria to improve treatment in cancer patients.

Cancer Theranostics

Cancer theranostics, which combine both diagnostics and therapy in one step, is emerging technology for precision medicine. We are currently investigating specific cancer-targeting biomarkers using phage display technology and modular engineering technology developing repebody which is a non-antibody protein scaffold for tumor targeting.

Infection imaging

Diagnosis and therapeutic monitoring of infection using imaging technology is currently investigating in our lab. Infection imaging, especially bacteria-specific target imaging, offers advantages of early diagnosis with higher sensitivity and whole body evaluation of infected sites. We are developing the imaging probes targeting microorganism or their environment to visualize the infection.

Pain imaging

We are developing molecular imaging probes and photoacoustic imaging technology to visualize neuropathic pain pathway in central and peripheral nervous systems. Our goal is to localize pain, quantify the intensity of pain, and identify the mechanism of pain by novel imaging method. Strategies are being tested in small animal models.

Cardiovascular imaging

We are developing cardiovascular imaging tracers to assess myocardial blood flow, infarcted tissue, or vasculature. The single photon emission computed tomography (SPECT) and positron emission tomography (PET) tracers widely used to diagnose various cardiovascular disease including ischemic heart disease in clinics, but have several limitations such as short half-life and low image quality. Our aim is developing novel cardiovascular imaging tracers to overcome limitations of previous tracers and lead excellent image quality.
