  • Publication number: 20220288104
    Abstract: The present disclosure provides methods of inhibiting amyloid synthesis in a subject using cyclodextrin and analogs thereof. Small molecules (cyclodextrin) reverse APOE4-associated cholesterol phenotypes and lead to significantly improved myelination both human in vitro cultures and APOE4 targeted replacement mice. This demonstrates that APOE4 alters cholesterol synthesis and transport in oligodendrocytes which impairs myelination. Collectively, this work uncovers a pathogenic role of APOE4 in oligodendrocytes and myelination and enables therapeutic opportunities for Alzheimer's Disease.

  • Publication number: 20220233879
    Abstract: Devices, systems, and methods for a treating dementia or Alzheimer's disease in a subject in need thereof. In one example, combined auditory and visual stimuli having a frequency of about 20 Hz to about 60 Hz, and more specifically about 40 Hz, are non-invasively delivered to the subject to induce synchronized gamma oscillations in at least one brain region of the subject. In particular, pursuant to various treatment and exposure protocols, combined auditory and visual stimulation (as opposed to auditory or visual stimulation alone) promotes a microglia response in the medial prefrontal cortex (mPFC). More generally, combined auditory and visual stimulation induces an extended microglia clustering response in the auditory cortex, the visual cortex, and the mPFC.

  • Publication number: 20220040496
    Abstract: Devices, systems, and methods for treating dementia or Alzheimer's disease in a subject in need thereof. In one example, chronic visual stimuli having a frequency of about 30 Hz to about 50 Hz, and more specifically about 40 Hz, are non-invasively delivered to the subject to entrain gamma oscillations in multiple brain regions of the subject, including the prefrontal cortex (PFC) and the hippocampus. The entrained gamma oscillations modulate neuronal activity across multiple brain regions (e.g., facilitate functional binding of neural networks at low gamma frequencies) to induce various neuroprotective effects (e.g., amelioration of amyloid plaques and tau hyper-phosphorylation) and reduce neurodegeneration. Neuronal activity mediated by the chronic visual stimuli reduces an immune response in microglia and ameliorates aberrantly modified genes and proteins involved in membrane trafficking, intracellular transport, synaptic function, neuroinflammation and DNA damage response.
