Cerebellar Neurons In Creutzfeldt Jakob Disease is a cell type relevant to neurodegenerative disease research. This page covers its role in brain function, involvement in disease processes, and significance for therapeutic strategies.
Creutzfeldt-Jakob disease (CJD) is a fatal prion disease characterized by rapid progressive dementia, ataxia, and myoclonus. Cerebellar involvement is a hallmark feature, contributing to the characteristic movement disorders.
- Glycoform ratio: Distinctive 3-band pattern on Western blot
- Conformational change: PrPC to PrPSc conversion
- Amyloid fibrils: Spongiform degeneration
- Cerebellar granule cells: Early and severe involvement
- Purkinje cells: Variable involvement
- Deep cerebellar nuclei: Motor coordination deficits
- Climbing fibers: From inferior olivary nucleus
- Mossy fibers: From spinal cord and brainstem
- Vestibular inputs: From vestibular nuclei
- Deep cerebellar nuclei: Dentate, emboliform, globose, fastigial
- ** Cerebello-thalamic projections**: To motor cortex
- Cerebello-vestibular projections: To vestibular nuclei
- Gait instability: Early manifestation
- Limb ataxia: Appendicular coordination loss
- Truncal ataxia: Postural instability
- Stimulus-sensitive: Provoked by sudden stimuli
- Axial myoclonus: Neck and trunk jerking
- Late-stage: Generalized myoclonus
