La muerte de las células cerebrales humanas inducida por el ligando inductor de apoptosis relacionado con el factor
Lancet (London, England)
|October 7, 2000
Resumen
El ligando inductor de apoptosis relacionado con el factor de necrosis tumoral (TRAIL) induce la muerte de las células cerebrales, lo que desafía su uso para la terapia de tumores cerebrales. Sin embargo, las células T que expresan TRAIL pueden ofrecer un objetivo para el tratamiento de la esclerosis múltiple.
Área de la Ciencia:
- La neurociencia es la neurociencia.
- Inmunología Inmunología.
- Biología celular Biología celular.
Sus antecedentes:
- Inicialmente se pensó que el ligando inductor de apoptosis relacionado con el factor de necrosis tumoral (TRAIL) inducía selectivamente la apoptosis en las células tumorales.
- Esta selectividad sugiere el potencial de TRAIL como una terapia antitumoral segura.
- Sin embargo, la susceptibilidad de los hepatocitos humanos normales a TRAIL planteó preocupaciones de seguridad.
Objetivo del estudio:
- Para investigar el efecto de TRAIL en las células cerebrales humanas.
- Evaluar las implicaciones de la apoptosis inducida por TRAIL en el cerebro para aplicaciones terapéuticas.
Principales métodos:
- El estudio consistió en investigar la inducción de la apoptosis por TRAIL en el tejido cerebral humano.
- El análisis se centró en los mecanismos celulares y las implicaciones de la muerte celular mediada por TRAIL.
Principales resultados:
- Se descubrió que TRAIL induce la apoptosis en las células cerebrales humanas.
- Este hallazgo contradice el supuesto previo de la citotoxicidad tumoral específica de TRAIL.
- Se identificaron células T neuroinflamatorias que expresan TRAIL como potenciales mediadores de la apoptosis del tejido cerebral.
Conclusiones:
- La inducción de la apoptosis en el cerebro humano por TRAIL argumenta en contra de su uso en el tratamiento de tumores cerebrales humanos.
- TRAIL expresado por células T neuroinflamatorias presenta un objetivo terapéutico potencial para condiciones como la esclerosis múltiple, donde la apoptosis del tejido cerebral está implicada.

01:00Enzyme-linked Receptors
Enzyme-linked receptors are proteins that act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of receptors that include the receptor tyrosine kinase (RTK) family. Many growth factors and hormones bind to and activate the RTKs.
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...

01:30Overview of Cell Death
Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the 20th century...

01:17The Extrinsic Apoptotic Pathway
The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...
01:31The Intrinsic Apoptotic Pathway
Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
01:17Phagocytosis of Apoptotic Cells
Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or immature dendritic cells. Non-professional phagocytes such as epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes.
Normal cells contain receptors that prevent them from being recognized by phagocytes.

01:18Autophagic Cell Death
Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.
