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.

Selective laser vaporization of polypropylene mesh in tissue

  Motivation for the study Surgical mesh is used to treat female stress urinary incontinence (SUI) and transvaginal pelvic organ prolapse (POP). However, erosion of this synthetic, non-absorbable mesh is a common complication and in more than half of these cases, a surgical excision of the mesh in the operating room is required. The mesh removal is technically challenging, may damage healthy adjacent tissues, and in some cases must be repeated several times. This study aims to explore the feasibility of selective laser vaporization, which Continue reading →Customer case University of North Carolina at Charlotte is a public research university founded in 1946.

ML7710 for photoimmunotherapy against regulatory T cells in tumors

    Results Tumor growth was significantly suppressed by photoimmunotherapy, compared to control or IgG without light activation. Tumor growth suppression, as well as overall survival after photoimmunotherapy, were significantly better with F(ab´)2 fragments than with full IgG. This efficacy improvement might be related to killer T cells, which were detected in much higher numbers after photoimmunotherapy with F(ab´)2 fragments and are key cells for the generation of efficient systemic antitumor immunity.       Related Modulight products and Services   Related Publications The Effect Continue reading →Customer case The Laboratory of Molecular Theranostics is a major research section of the Molecular Imaging Program at National Cancer Institute (NCI) and is led by Dr. Hisataka Kobayashi.

Novel antimicrobial phototherapy against emerging infectious diseases

      Results PIAS-treated pathogens were effectively eradicated upon NIR illumination. The efficacy of PIAS was dependent on the NIR light dose, 50 J/cm2 eradicating all MRSA from the rat nasal tract (Figure 1). PIAS also saved all mice from fatal MRSA infections, similar to VCM+RFP antibiotics and even more effectively than VCM antibiotics alone (Figure 2). Unlike the antibiotics, PIAS acted selectively on the target pathogen and did not affect host’s normal intestinal microflora (Figure 3). Also generation of microbial resistance, common problem Continue reading →Customer case Research by: The Jikei University School of Medicine located in Tokyo, Japan and founded in 1881 is today one of the three major private medical schools in Japan.

Development of heat shock protein 90-targeted PDT for inflammatory breast cancer

Motivation of the study In photodynamic therapy (PDT), systemically administered photosensitizer is activated within the tumor using focused near-infrared light, typically a laser with a wavelength matching the absorption peak of the photosensitizer. Several photosensitizers have been clinically approved for the treatment of different cancers; however, their accumulation is non-tumor exclusive which exposes healthy tissues to side effects like daylight-induced phototoxicity. A promising strategy to improve tumor selectivity is to couple photosensitizer to a tumor-targeting agent that binds to a specific antigen expressed on the Continue reading →Customer case Research by: Duke University, founded in 1924, is one of the leading and wealthiest private research universities in the USA.

ML7710 for fluorescence imaging: Detection of colorectal polyps in humans using c-Met targeted fluorescent peptide

Motivation for the study Polyps are small growths on the inner lining of the colon or rectum, affecting around 1 in 4 people over the age of 50. Certain types of polyps may eventually become cancerous, and colon cancer prevention relies on colonoscopy using white light to detect and remove the polyps. However, small and flat polyps are difficult to detect and frequently missed with this technique. More precise methods to detect polyps before they progress to colorectal cancer are urgently needed.
