Corpusculum Leweyi[1] est aggregatio proteinorum (alpha-synucleini[2]) morbosa intra cellularem ad morbum Parkinsonianum et dementiam cum corpusculis Leweyi pertinentes[3], morbus corpusculorum Leweyi dictus. Morbi corpusculorum Leweyi sunt morbus Parkinsonianus, dementia cum corpusculis Leweyi, imbecillitas autonomica pura.

Corpuscula Leweyi. Regiones substantiae nigrae in morbi Parkinson aegroto cum corpusculis Leweyi et neuronis implicitis, magnificationes variae. Series superior, magnificatio sesxagesimuplus (60x): inclusiones intraneuronales alpha-synucleini ad corpuscula Leweyi formandos aggregatae. Series inferior, magnificatio vicesimuplus (20x): imagines neuronos implicatos atque corpuscula Leweyi rotunda magnitudinum variarum ostendunt.

Natura corpusculorum Leweyi

recensere

Corpusculum Leweyi corpusculum inclusionis

recensere
  Conferatur pagina principalis: Corpusculum inclusionis.

Corpusculum inclusionis est substantia stabilis intracellularis, quae vel intra cytoplasmate vel intra nucleum (sive utrumque). Corpuscula Leweyi ex plus quam nonaginta proteinis, imprimis α-synucleino, constituta sunt. Aggregatio non solum in cytoplasmate somatis (notione corpusculum Leweyi sensu stricto) sed etiam in neurito (notione neuritum Leweyi) fit.

Morbus corpusculorum Leweyi

recensere

Notio morbi corpusculorum Leweyi ad spectrum morborum diversorum cum diffusione corpusculorum Leweyi late in systema nervosum refert. Exempla sunt morbus Parkinsonianus, dementia cum corpusculis Leweyi, imbecillitas autonomica pura. Omnes cum perturbationibus gastrointestinalibus coniuncti sunt, ut scientia novissime systema nervosum entericum investigat. Inter effectus ibidem videtur, ut textus oesophagi (imprimis tunicae muscularis propriae) progressum morbi indicet[4].

Corpora Leweyi et morbus Parkinson

recensere

In morbo Parkinson corpusculis Leweyi plus quam nonaginta producta genorum insunt[5], ut alpha-synucleinum, DJ-1, LRKK2, parkin, mitochondrialis PTEN inducta kinasis 1 (PINK-1), at etiam mitochondriorum enzyma, molecula systematis ubiquitini et proteasomatum, autophagiae, formationis aggresomatum. PINK-1 mitochondria protegit. Aggresomata sunt proteinorum non recte plicatorum aggregationes.

Adhuc diversa systemata morborum Leweyi edita sunt:

  • Stadia Braakiensia (2003)[6]
  • Consensus criteria secundum McKeith (2005)[7]
  • Consensus criteria secundum Leverenz (2008)[8]
  • Systema statuum unificatum secundum Beach (2009)[9]
  • Consensus criteria neuropathologica secundum Attems (2021)[10]

Consensus criteria 2021 secundum

Consensus criteria anni 2021 ad locos affectos referunt, si enim commutationes pathologicae in regiones inveniuntur has:

Quisque locus ita positivus aestimatur, ut primum signa histopathologica corpusculorum Leweyi cognoscantur[11].
