organelle

 [or″gah-nel´]
any of the organized cytoplasmic structures of distinctive morphology and function present in all eukaryotic cells, including such structures as the nucleus, mitochondria, lysosomes, peroxisomes, Golgi apparatus, and endoplasmic reticulum, as well as chloroplasts in plants and cilia and flagella in protozoa.

or·gan·elle

(or'găn-el),
One of the specialized parts of a protozoan or tissue cell; these subcellular units include mitochondria, the Golgi apparatus, nucleus and centrioles, granular and agranular endoplasmic reticulum, vacuoles, microsomes, lysosomes, plasma membrane, and certain fibrils, as well as plastids of plant cells.
Synonym(s): cell organelle, organoid (3)
[G. organon, organ, + Fr. -elle, dim. suffix, fr. L. -ella]

organelle

Any one of the bodies forming the internal functional components, or ‘little organs’, of the cell. The organelles include MITOCHONDRIA, the GOLGI APPARATUS, the ENDOPLASMIC RETICULUM, RIBOSOMES, LYSOSOMES and the CENTRIOLES.

organelle

any part of a cell that has a particular structural or functional role, such as FLAGELLUM or a MITOCHONDRION. Organelles are analogous with organs in the body of multicellular organisms.

Organelle

Specialized structure within a cell, which is separated from the rest of the cell by a membrane composed of lipids and proteins, where chemical and metabolic functions take place.

Tanto los cambios en la fusion y fision mitocondrial, como las alteraciones en el transporte de esta organela a traves de los axones (30), han sido identificados como causas relacionadas con la disfuncion neuronal y el aumento de la susceptibilidad a la muerte de neuronas en pacientes con enfermedad de Huntington, en quienes se ha reportado una disfuncion mitocondrial en los complejos de la cadena respiratoria y en las enzimas del ciclo del acido tricarboxilico del cerebro (30).
La disfuncion mitocondrial, especialmente la induccion de la permeabilidad de la membrana de esta organela, ha sido implicada en una cascada de eventos que inducen a la apoptosis, la cual esta regulada en gran parte por la mitocondria y mas especificamente por las caspasas (14).
Las enfermedades mitocondriales estan catalogadas como las alteraciones metabolicas mas comunes, si se abarcan todas las patologias que involucran a esta organela, consideradas como patologias que causan gran morbilidad y mortalidad prematura (21), tanto por la patogenia de la enfermedad, como por el dificil diagnostico y poca efectividad de los tratamientos (1).
Em situacoes extremas, esses processos resultariam na perda de eficiencia funcional dessas organelas e na morte cellular (35).
Todos estos hallazgos constituyen fuertes evidencias acerca de la existencia de las contrapartes vegetales de estas proteinas, asi como del papel regulador de la mitocondria y otros organela propios de las plantas como son los cloroplastos.
