Azadipyrromethenes (ADPM) is a class of dyes used experimentally as photosensitizers for photodynamic therapy. [1] [2]
Some derivatives can usefully absorb in the near-infrared. [3] It has also been demonstrated that supramolecular coordination of an anion can switch-off the photosensitising ability of azadipyrromethene derivatives, [4] which could improve the selectivity of photodynamic therapy agents.
Immunotherapy or biological therapy is the treatment of disease by activating or suppressing the immune system. Immunotherapies designed to elicit or amplify an immune response are classified as activation immunotherapies, while immunotherapies that reduce or suppress are classified as suppression immunotherapies. Immunotherapy is under preliminary research for its potential to treat various forms of cancer.
Photodynamic therapy (PDT) is a form of phototherapy involving light and a photosensitizing chemical substance used in conjunction with molecular oxygen to elicit cell death (phototoxicity).
δ-Aminolevulinic acid, an endogenous non-proteinogenic amino acid, is the first compound in the porphyrin synthesis pathway, the pathway that leads to heme in mammals, as well as chlorophyll in plants.
Light therapy, also called phototherapy or bright light therapy is the exposure to direct sunlight or artificial light at controlled wavelengths in order to treat a variety of medical disorders, including seasonal affective disorder (SAD), circadian rhythm sleep-wake disorders, cancers, and skin wound infections. Treating skin conditions such as neurodermatitis, psoriasis, acne vulgaris, and eczema with ultraviolet light is called ultraviolet light therapy.
An oncolytic virus is a virus that preferentially infects and kills cancer cells. As the infected cancer cells are destroyed by oncolysis, they release new infectious virus particles or virions to help destroy the remaining tumour. Oncolytic viruses are thought not only to cause direct destruction of the tumour cells, but also to stimulate host anti-tumour immune system responses. Oncolytic viruses also have the ability to affect the tumor micro-environment in multiple ways.
An angiogenesis inhibitor is a substance that inhibits the growth of new blood vessels (angiogenesis). Some angiogenesis inhibitors are endogenous and a normal part of the body's control and others are obtained exogenously through pharmaceutical drugs or diet.
Interleukin-29 (IL-29) is a cytokine and it belongs to type III interferons group, also termed interferons λ (IFN-λ). IL-29 plays an important role in the immune response against pathogenes and especially against viruses by mechanisms similar to type I interferons, but targeting primarily cells of epithelial origin and hepatocytes.
Photothermal therapy (PTT) refers to efforts to use electromagnetic radiation for the treatment of various medical conditions, including cancer. This approach is an extension of photodynamic therapy, in which a photosensitizer is excited with specific band light. This activation brings the sensitizer to an excited state where it then releases vibrational energy (heat), which is what kills the targeted cells.
Temoporfin (INN) is a photosensitizer used in photodynamic therapy for the treatment of squamous cell carcinoma of the head and neck . It is marketed in the European Union under the brand name Foscan. The U.S. Food and Drug Administration (FDA) declined to approve Foscan in 2000. The EU approved its use in June 2001.
Mitozolomide (INN) is an antineoplastic. It is an imidazotetrazine derivative.
Joshua T. Mendell is an American molecular biologist who is a professor of molecular biology at the University of Texas Southwestern Medical Center, where he is a Howard Hughes Medical Institute Investigator. Before moving to UT Southwestern, Mendell was a Howard Hughes Medical Institute early career scientist at Johns Hopkins School of Medicine. His molecular biology research examines microRNA (miRNA) regulation and function, with particular emphasis on miRNAs and cancer.
Gustav Gaudernack is a scientist working in the development of cancer vaccines and cancer immunotherapy. He has developed various strategies in immunological treatment of cancer. He is involved in several ongoing cellular and immuno-gene therapeutic clinical trials and his research group has put major efforts into the development of various T cell-based immunotherapeutic strategies.
Photoimmunotherapy (PIT) is an oncological treatment that combines photodynamic therapy of tumor with immunotherapy treatment. Combining photodynamic therapy with immunotherapy enhances the immunostimulating response and has synergistic effects for metastatic cancer treatment.
Adenovirus varieties have been explored extensively as a viral vector for gene therapy and also as an oncolytic virus.
DNA-directed RNA interference (ddRNAi) is a gene-silencing technique that utilizes DNA constructs to activate an animal cell's endogenous RNA interference (RNAi) pathways. DNA constructs are designed to express self-complementary double-stranded RNAs, typically short-hairpin RNAs, that bring about the silencing of a target gene or genes once processed. Any RNA, including endogenous messenger RNA (mRNAs) or viral RNAs, can be silenced by designing constructs to express double-stranded RNA complementary to the desired mRNA target.
Anti–vascular endothelial growth factor therapy, also known as anti-VEGF therapy or medication, is the use of medications that block vascular endothelial growth factor. This is done in the treatment of certain cancers and in age-related macular degeneration. They can involve monoclonal antibodies such as bevacizumab, antibody derivatives such as ranibizumab (Lucentis), or orally-available small molecules that inhibit the tyrosine kinases stimulated by VEGF: sunitinib, sorafenib, axitinib, and pazopanib.
This is a historical timeline of the development and progress of cancer treatments, which includes time of discovery, progress, and approval of the treatments.
Combinatorial ablation and immunotherapy is an oncological treatment that combines various tumor-ablation techniques with immunotherapy treatment. Combining ablation therapy of tumors with immunotherapy enhances the immunostimulating response and has synergistic effects for curative metastatic cancer treatment. Various ablative techniques are utilized including cryoablation, radiofrequency ablation, laser ablation, photodynamic ablation, stereotactic radiation therapy, alpha-emitting radiation therapy, hyperthermia therapy, HIFU. Thus, combinatorial ablation of tumors and immunotherapy is a way of achieving an autologous, in-vivo tumor lysate vaccine and treating metastatic disease.
Individualized medicine tailors treatment to a single patient. The term refers to an individual, truly personalized medicine that strives to treat each patient on the basis of his own individual biology.
Light-emitting diode therapy (LEDT) is a clinical approach that applies different wavelengths of light to cure diseases or conditions with skin-safe lights. Following NASA's innovation in the 1990s with Light Emitting Diodes (LEDs) that emit a specific narrow light spectrum, LED Therapy (LEDT) showed significant potential. The high precision of narrow-band LED therapy enabled its first use in clinical practices. The commonly used lights in LEDT are blue, red, green, yellow, and infrared (IR).
