Gastrointestinal tract cleavage of alpha-synuclein by asparaginyl endopeptidase leads to Parkinson's disease
Pathologic α-synuclein (α-syn) aggregates from the gastrointestinal (GI) tract may contribute to Parkinson's disease (PD). Xiang et al.¹ report in Neuron that enteric nervous system-specific expression of asparaginyl endopeptidase (AEP)-truncated α-syn and tau spreads to the brain, synergistically causing PD-related neurodegeneration and neurobehavioral deficits.
Microbiota-derived lysophosphatidylcholine alleviates Alzheimer's disease pathology via suppressing ferroptosis
Alzheimer's disease (AD) is a pervasive neurodegenerative disorder, and new approaches for its prevention and therapy are critically needed. Here, we elucidate a gut-microbiome-brain axis that offers actionable perspectives for achieving this objective. Using the 5xFAD mouse model, we identify increased Clostridium abundance and decreased Bacteroides abundance as key features associated with β-amyloid (Aβ) burden. Treatment with Bacteroides ovatus, or its associated metabolite...
