Recently, we reported the photoimmuno-antimicrobial strategy (PIAS), a type of photoimmunotechnology, that enables molecularly targeted elimination of a wide range of microbes, including the viral pathogen severe acute respiratory syndrome coronavirus 2 and the multidrug-resistant bacterial pathogen Continue reading →

 Modulight Spotlights: LASER-SHARP RESEARCH – September 2023 Head & neck cancer is world’s sixth most common cancer, with increasing incidence and poor survival. A new study by P. Enzian & R. Rahmanzadeh at University of Lübeck, studied combining chemotherapy with photochemical internalization for more effective H&N cancer treatment in vitro. Photochemical internalization using photosensitizer fimaporfin, activated with Modulight’s ML6600 laser, was shown to increase drug’s efficacy by means of better drug delivery inside the cells. As a result, tumor cell death was achieved using 20-fold Continue reading →

 Modulight Spotlights: LASER-SHARP RESEARCH – August 2023 Interleukin 15 (IL-15) is promising candidate for cancer immunotherapy, since it is an inducer of differentiation and proliferation of killer T cells and NK cells. A new study by Fukushima et al. at NCI, published in Molecular Cancer Therapeutics, shows increase in therapeutic efficacy in vivo when IL15 was combined with photoimmunotherapy using ML7710 laser system. Intratumoral injection of IL-15 also boosted the immune responses against both the primary tumor as well as abscopal effect eradicating distant, untreated tumor.​ ​​ Read original publication Modulight Continue reading →

Published in: Cardiovascular and Interventional Radiology Authors: Timothy M. Baran, Ashwani Kumar Sharma    Published in: Cardiovascular and Interventional Radiology Authors: Timothy M. Baran, Ashwani Kumar Sharma   This article presents a successful case study from an ongoing Phase 1 clinical trial where methylene blue together with ML7710 is used to eradicate bacteria and biofilm in the treatment of persistent abscesses. The potential of Photodynamic Therapy (PDT) is explored as an adjunct treatment for recurrent or challenging-to-manage abdominal abscesses during percutaneous drainage procedures. Despite advancements in abscess drainage techniques and antibiotics, some cases exhibit low response rates and recurrences, Continue reading →

Choyke, Hisataka Kobayashi   Interleukin 15 (IL-15) is inducer of differentiation and proliferation of CD8+ T cells and NK cells and thus promising candidate for cancer immunotherapy. This study showed therapeutic efficacy increase in vivo when IL15 was combined with cancer cell-targeted photoimmunotherapy using ML7710 laser system. Intratumoral injection of IL-15 was more effective than intraperitoneal in suppressing tumor growth and inducing intratumoral immune responses, Continue reading →
