   Modulight Spotlights: LASER-SHARP RESEARCH – November 2022 This month’s Spotlight goes to Susumu Yamashita et al. for promising findings on novel light-based therapy for breast cancer treatment, published in a journal Cancer Medicine. Their teams at Olympus and Tokyo University of Agriculture and Technology developed trastuzumab-conjugated photo-absorber (Tra-IR700) which targets HER2-positive breast cancer cells. This treatment strategy is particularly relevant, since HER2 biomarker is associated with poor survival of breast cancer patients and often has intrinsic or acquired resistance to standard trastuzumab therapy. Especially for these patients, Tra-IR700 activated with Continue reading →

Combining photoimmunotherapy with immune checkpoint inhibition

Motivation for the study The motivation was to study if photoimmunotherapy could enhance anti-tumor immunity when combined with immune checkpoint inhibition. CD44-targeted photoimmunotherapy was applied against poorly immunogenic, “cold” tumor and antitumor effect was studied alone and in combination with anti-PD-1 immune checkpoint inhibition. Sensitization of this “cold” tumor to immune checkpoint inhibition after photoimmunotherapy would mean that the tumor has been converted into highly immunogenic, “hot” tumor infiltrated with killer T cells mainly responsible for eradicating the tumor. The formation of immunological antitumor memory Continue reading →Customer case The Laboratory of Molecular Theranostics at National Cancer Institute (NCI) is a major research section of the Molecular Imaging Program at National Cancer Institute (NCI) and is led by Dr. Hisataka Kobayashi who is the father of photoimmunotherapy. The ground-breaking research includes the development of imaging and theranostic probes with a particular emphasis on optical probes, which can aid in cancer detection during cancer resection or endoscopy.
