The SAR-CoV-2 virus has evolved to co-exist with human hosts, albeit at a substantial energetic cost resulting in post-infection neurological manifestations [Neuro-post-acute sequelae of SARS-CoV-2 infection (PASC)] that significantly impact public health and economic productivity on global scale. One the main molecular mechanisms responsible for development Neuro-PASC, individuals all ages, is formation inadequate proteolysis/clearance phase-separated amyloid crystalline aggregates—a hallmark feature aging-related neurodegenerative disorders. Amyloidogenesis during viral persistence natural, inevitable, protective defense response exacerbated by SARS-CoV-2. Acting as chemical catalyst, accelerates hydrophobic collapse heterogeneous nucleation amorphous amyloids into stable β-sheet aggregates. clearance aggregates most effective slow wave sleep, when high levels adenosine triphosphate (ATP)—a biphasic modulator biomolecular condensates—and melatonin are available solubilize removal. dysregulation mitochondrial dynamics SARS-CoV-2, particular fusion fission homeostasis, impairs proper distinct subpopulations can remedy challenges created diversion substrates away from oxidative phosphorylation towards glycolysis support replication maintenance. subsequent reduction ATP inhibition synthesis sleep results incomplete brain aggregates, leading commonly associated age-related Exogenous not only prevents dysfunction but also elevates production, effectively augmenting solubilizing effect moiety ensure timely, optimal disaggregation pathogenic prevention attenuation Neuro-PASC.
