Microglia-derived nanovesicles synchronize macroautophagy and chaperone-mediated autophagy for Alzheimer’s disease therapy

Min Li, Min Li, Shuang Chen et al. · 2025 · Signal Transduction and Targeted Therapy

Dysregulated autophagy is a hallmark of Alzheimer's disease (AD), yet the extent of impairment in macroautophagy and chaperone-mediated autophagy (CMA) remains unclear. Here, we show that both pathways are disrupted in AD model mice, preceding β-amyloid accumulation and driving disease progression. However, therapeutic autophagy modulation is severely restricted by the blood-brain barrier (BBB). To overcome this, we developed Microglia-Liposome Fusion Extrusion (MiLi-FE), a method to engineer microglia-derived nanovesicles (AR@ENV) for the codelivery of AR7 (a CMA inducer) and rapamycin (a mac

Gut microbiome and its metabolites in liver cirrhosis: mechanisms and clinical implications

Luyuan Chang, Yang Liu, Haipeng Li et al. · 2025 · Frontiers in Cellular and Infection Microbiology

Cirrhosis remains a significant global health burden, causing approximately 1.4-1.5 million deaths each year and contributing to nearly 46 million disability-adjusted life years (DALYs) worldwide. Increasing evidence identifies the gut-liver axis as a central driver of disease progression, wherein intestinal dysbiosis, barrier disruption, and microbe-derived metabolites collectively exacerbate inflammation, fibrogenesis, and related complications. Across more than 40 recent studies, gut microbial α-diversity declined by 30-60%, and over 80% reported a marked depletion of short-chain fatty acid

Unraveling the oral microbiome's role in Alzheimer's disease: From pathophysiology to therapeutic potential

Gilliana Rozenblum, Karima Ait‐Aissa, G. E. D. Zahran et al. · 2025 · Alzheimer s & Dementia

Oral dysbiosis contributes to Alzheimer's disease (AD) by promoting neuroinflammation. Pathobionts such as Porphyromonas gingivalis, Treponema denticola, and Fusobacterium nucleatum release virulence factors that induce amyloid beta aggregation and tau hyperphosphorylation, while the loss of commensals like Streptococcus salivarius and Neisseria spp. impairs anti-inflammatory protection, worsening neuronal damage. P. gingivalis is strongly linked to an increased risk of AD, especially in individuals with systemic conditions like diabetes, hypertension, and chronic kidney disease. Its presence

Hierarchical interactions between sensory cortices defy predictive coding

Jacob A. Westerberg, Pieter R. Roelfsema · 2025 · Trends in Cognitive Sciences

Perceptual experience depends on recurrent interactions between lower and higher cortices. One theory, predictive coding, posits that feedback from higher to lower brain regions decreases neuronal activity predicted by higher-level representations. Despite the widespread adoption of predictive coding in neuroscience, the correspondence to neurophysiological findings in sensory cortices remains elusive. Here, we review how the canonical patterns of intra- and inter-cortical interactions that occur during perception and shifts of attention deviate from those predicted by predictive coding. We ar

Population-scale sequencing resolves determinants of persistent EBV DNA

Sherry S. Y. Nyeo, Erin M. Cumming, Oliver S. Burren et al. · 2026 · Nature

Abstract Epstein–Barr virus (EBV) is an endemic herpesvirus implicated in autoimmunity, cancer and neurological disorders. Although primary infection is often subclinical, persistent EBV infection can drive immune dysregulation and long-term complications. Despite the ubiquity of infection, the determinants of EBV persistence following primary exposure remain poorly understood, although human genetic variation partially contributes to this phenotypic spectrum 1–3 . Here we demonstrate that existing whole genome sequencing (WGS) data of human populations can be used to quantify persistent EBV D
