Fibril

 

a filamentous structure found in the cells and tissues of animals and plants. Fibrils include formations of various origin and functional significance. They may be examined with a light microscope (for example, collagen and elastic fibers, myofibrils, and tonofibrils) or an electron microscope (for example, the protofibrils of muscles and cytoplasmic microfibrils).

Lewis et al, en 2006, (42), buscando determinar precisamente las implicaciones biologicas directas de los diferentes alelos del polimorfismo, reportan que el alelo met 129 en una conformacion parcialmente desnaturalizada (como podria ocurrir in vivo) tiene una profunda influencia en la habilidad de la proteina para formar fibrillas amiloides espontaneamente, generando, asi, una clara conexion entre el polimorfismo 129 y el riesgo aumentado a desarrollar la enfermedad.
