Buthionine sulfoximine (BSO) is a sulfoximine derivative which reduces levels of glutathione and is being investigated as an adjunct with chemotherapy in the treatment of cancer. [1] The compound inhibits gamma-glutamylcysteine synthetase, the enzyme required in the first step of glutathione synthesis.
Glutathione is the most abundant non-protein thiol (R−SH-containing compound) in animal cells, ranging from 0.5 to 10 mmol/L. It is present in the cytosol and the organelles . [ 6 ] The concentration of glutathione in the cytoplasm is significantly higher (ranging from 0.5-10 mM) compared to extracellular fluids (2-20 μM), reaching levels up ...
T-cell transfer therapy: a treatment that takes T-cells from the tumor and selects or changes them in the lab to better attack cancer cells, then reintroduces them into the patient. Monoclonal antibodies: designed to bind to specific targets on cancer cells, marking cancer cells so that they will be better seen and destroyed by the immune system.
Cancer cells are formed in our body almost every day but we are not affected by them. This is because they are immediately destroyed by the body's immune system. The immune system is a complex network of cells and organs comprising lymphocytes, macrophages, Dendritic cells, Natural Killer cells (NK Cell), Cytotoxic T Lymphocytes (CTL), etc., that work together to defend the body against ...
The diagram above represents the process of chimeric antigen receptor T-cell therapy (CAR), this is a method of immunotherapy, which is a growing practice in the treatment of cancer. The final result should be a production of equipped T-cells that can recognize and fight the infected cancer cells in the body.
Immune cells such as T-cells are usually isolated from patients for expansion or engineering purposes and reinfused back into patients to fight diseases using their own immune system. A major application of cellular adoptive therapy is cancer treatment, as the immune system plays a vital role in the development and growth of cancer. [1]
There are a few possible causes of resistance in cancer, one of which is the presence of small pumps on the surface of cancer cells that actively move chemotherapy from inside the cell to the outside. Cancer cells produce high amounts of these pumps, known as p-glycoprotein, in order to protect themselves from chemotherapeutics. Research on p ...
Cell therapy (also called cellular therapy, cell transplantation, or cytotherapy) is a therapy in which viable cells are injected, grafted or implanted into a patient in order to effectuate a medicinal effect, [1] for example, by transplanting T-cells capable of fighting cancer cells via cell-mediated immunity in the course of immunotherapy, or ...
