    Insights

    Scrapie-infected mouse brain extract significantly increased cell proliferation in cell cultures. Healthy mouse brain extract had no effect, suggesting gliosis is key in prion disease brain changes.

    Area of Science:

    • Neuroscience
    • Cell Biology
    • Pathology

    Context:

    • Prion diseases, such as scrapie, cause significant neuropathology.
    • Understanding the cellular mechanisms driving prion disease progression is crucial.

    Purpose:

    • To investigate the effect of scrapie-infected cerebral extract on cell proliferation.
    • To explore the role of gliosis in prion disease pathomorphology.

    Summary:

    • Experiments using three cell lines showed that cerebral extract from scrapie-infected mice induced rapid cellular proliferation within 3 days.
    • Cerebral extract from healthy mice did not affect cell reproduction rates.
    • These findings, combined with existing literature, suggest gliosis plays a primary role in cerebral tissue alterations observed in prion diseases.

    Impact:

    • Provides evidence for the role of cellular proliferation and gliosis in prion disease pathogenesis.
    • Highlights potential cellular targets for therapeutic interventions in prion diseases.
    • Contributes to understanding the fundamental mechanisms of neurodegeneration in prion-related disorders.

    Amyloid Fibrils03:03

    Amyloid Fibrils

    Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
    Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining, normally used to...

    Encephalitis l: Introduction

    Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...

    Encephalitis ll: Pathophysiology

    Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...

    Alzheimer Disease ll: Pathophysiology

    Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...

    Parkinson Disease ll: Pathophysiology

    Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...
