An immunotoxin is an artificial protein consisting of a targeting portion linked to a toxin. When the protein binds to that cell, it is taken in through endocytosis, and the toxin kills the cell. They are used for the treatment of some kinds of cancer and a few viral infections.
This is a list of terms related to oncology. The original source for this list was the US National Cancer Institute's public domain Dictionary of Cancer Terms.
Chimeric antigen receptor T cells are T cells that have been genetically engineered to produce an artificial T-cell receptor.
Diphtheria toxin is an exotoxin secreted by Corynebacterium diphtheriae, the pathogenic bacterium that causes diphtheria. Unusually, the toxin gene is encoded by a bacteriophage. The toxin causes the disease in humans by gaining entry into the cell cytoplasm and inhibiting protein synthesis.
CD22, or cluster of differentiation-22, is a molecule belonging to the SIGLEC family of lectins. It is found on the surface of mature B cells and to a lesser extent on some immature B cells. Generally speaking, CD22 is a regulatory molecule that prevents the overactivation of the immune system and the development of autoimmune diseases.
Ira Pastan is an American scientist at the National Cancer Institute. He is a member of the National Academy of Sciences, a Fellow of the AAAS and the American Society of Microbiology. In 2009, he was awarded the prestigious International Antonio Feltrinelli Prize for Medicine. His wife, Linda Pastan, is an accomplished American poet.
Adenosquamous carcinoma is a type of cancer that contains two types of cells: squamous cells and gland-like cells. It has been associated with more aggressive characteristics when compared to adenocarcinoma in certain cancers.
An anti-CD22 immunotoxin is a monoclonal antibody linked to a cytotoxic agent. They are being studied in the treatment of some types of B-cell cancer.
Arctigenin is a lignan found in certain plants of the Asteraceae, including the greater burdock and Saussurea heteromalla. It has shown antiviral and anticancer effects in vitro. It is the aglycone of arctiin.
Spindle cell carcinoma is a type of cancer that begins in the skin or in tissues that line or cover internal organs and that contains long spindle-shaped cells. It is also called sarcomatoid carcinoma.
Ribonucleotide reductase inhibitors are a family of anti-cancer drugs that interfere with the growth of tumor cells by blocking the formation of deoxyribonucleotides.
Peripheral blood stem cell transplantation (PBSCT), also called "Peripheral stem cell support", is a method of replacing blood-forming stem cells destroyed, for example, by cancer treatment. PBSCT is now a much more common procedure than its bone marrow harvest equivalent, this is in-part due to the ease and less invasive nature of the procedure. Studies suggest that PBSCT has a better outcome in terms of the number of hematopoietic stem cell yield.
Precursor B-cell lymphoblastic leukemia is a form of lymphoid leukemia in which too many B-cell lymphoblasts are found in the blood and bone marrow. It is the most common type of acute lymphoblastic leukemia (ALL). It is sometimes additionally classified as a lymphoma, as designated leukemia/lymphoma.
Segmental resection is a surgical procedure to remove part of an organ or gland, as a sub-type of a resection, which might involve removing the whole body part. It may also be used to remove a tumor and normal tissue around it. In lung cancer surgery, segmental resection refers to removing a section of a lobe of the lung. The resection margin is the edge of the removed tissue; it is important that this shows free of cancerous cells on examination by a pathologist.
Monomethyl auristatin E (MMAE) is a synthetic antineoplastic agent. Because of its toxicity, it cannot be used as a drug itself; instead, it is linked to a monoclonal antibody (MAB) which directs it to the cancer cells. In International Nonproprietary Names for MMAE-MAB-conjugates, the name vedotin refers to MMAE plus its linking structure to the antibody. It is a potent antimitotic drug derived from peptides occurring in marine shell-less mollusc Dolabella auricularia called dolastatins which show potent activity in preclinical studies, both in vitro and in vivo, against a range of lymphomas, leukemia and solid tumors. These drugs show potency of up to 200 times that of vinblastine, another antimitotic drug used for Hodgkin lymphoma as well as other types of cancer.
Moxetumomab pasudotox is an anti-CD22 immunotoxin designed for the treatment of cancer.
Resimmune or A-dmDT390-bisFv(UCHT1) is an experimental drug — an anti-T cell immunotoxin — that is being investigated for treatment of T cell blood cancers such as cutaneous T cell lymphoma (CTCL). It was developed by Doctors Neville, Woo, and Liu while at the National Institutes of Health (NIH) and is under exclusive license to Angimmune, LLC. The therapy has potential applications for lymphomas and T cell driven autoimmune diseases, including multiple sclerosis, and graft-versus-host disease following stem cell or bone marrow transplant.
Monomethyl auristatin F (MMAF) is a synthetic antineoplastic agent. It is part of some experimental anti-cancer antibody-drug conjugates such as vorsetuzumab mafodotin and SGN-CD19A. In International Nonproprietary Names for MMAF-antibody-conjugates, the name mafodotin refers to MMAF plus its attachment structure to the antibody.
Camidanlumab tesirine is an antibody-drug conjugate (ADC) composed of a human antibody that binds to the protein CD25, conjugated to a pyrrolobenzodiazepine dimer toxin.
The experimental drug, developed by ADC Therapeutics is being tested in clinical trials for the treatment of B-cell Hodgkin's lymphoma (HL) and non-Hodgkin lymphoma (NHL), and for the treatment of B-cell acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML).
