Acta Neuropathologica: In organ-type brain tablet culture and in the body, neuron activity regulates the α and diffusion of ana-synth nucleoproteins.

Misfolded α-synaptic nucleoproteins (alphaSyn) form neuron encapsulations called Lewy small bodies (LBs) and Lewy axons (LNs), which are Parkinson's disease (PD) and Le The pathological characteristics of wy small body dementia (DLB), while the glial cell pulp inclusion (GCI) in multisyscular atrophy (MSA) also contains fiber alphaSyn, but is found in less protrusive glial cells rather than in neurons.
Syn pathology is also prevalent in the brains of alzheimer's disease (AD), while neurodegenerative diseases associated with alphaSyn pathology are often referred to as synth nuclear protein disease.
alphaSyn prefabribrised fiber (PFF) induces endo-alpha Syn aggregation, resulting in reduced synapse delivery.
neuron activity regulates the release of alphaSyn, however, whether neuron activity regulates the diffusion of alphaSyn pathology remains unknown.
here, we established a wild type (WT) mouse hema slice culture system and found that ca2 plus inflow and alphaSyn PFF intake in CA3 were higher than in CA1 sub-regions.
drug-enhanced neuron activity significantly increased alphaSyn pathological changes and accelerated the degeneration of dopamine-energy neurons in the development of sea horses or mid-brain slices treated by alphaSyn PFF.
, neuron over-activity has facilitated PFF transport along axons/tree protrusions in the microflow cavity.
unexpectedly, the neuron activity that enhances IRK2 G2019s mutation slice culture further increases alphaSyn pathology, especially LB formation more than WT slice culture.
Finally, after the injection of alphaSyn PFF and chemically occurring regulators into the back sprite of WT mice, both motor behavior and alphaSyn pathology were likely to deteriorate by increasing neuron activity, as they improved by reducing neuron activity.
, an in-depth understanding of the effects of neuron activity on alphaSyn aggregation and diffusion, as well as the vulnerability of dopamine-energy neurons, may provide new treatment strategies for patients with LBD.
: The full α human synapse (1-140) protein is expressed and purified in BL21 (DE3) RIL cells.
dilutes the recombined alphaSyn to 5 mg/mL in the sterile Durbeco PBS (Cellgro, Mediatech; pH adjusted to 7.0, no Ca2 plus or Mg2 plus), and then at 37 degrees C for 7 days at 1000 rpm continuous stirring culture for fibrosis.
the success of the serotonin-synthetic fibers by electron microscope, sesis study and the α-combination test.
the assembled alpha Syn PFF is calibrated and stored at -80 degrees C.
, neuron activity should be seen as the driving force behind the accelerated spread of alphaSyn pathology in human PD patients.
, regulating neuron activity could become a new treatment for synactal nucleocytosis.
