A novel electric field approach for improving cognitive function through ameliorating cell-specific pathology in P301S tauopathy mice
Alzheimer's Research & Therapy 2025 Sep
Abstract
Alzheimer’s disease (AD) is a devastating neurodegenerative disorder, with no effective treatment currently available. Recently, non-pharmacological therapy, especially gamma frequency stimulation has shown promising therapeutic effects in Alzheimer’s disease (AD) mouse models. Electric field (EF) is a non-invasive biophysical approach for neuronal protection. However, whether EF is beneficial in AD neuropathology remains unknown. In this study, we exposed the P301S tauopathy mouse model to EF at gamma frequency on the head. We demonstrated that EF treatment significantly improved the cognitive impairments in the P301S mice. This was accompanied by reduced tau pathologies, suppressed microglial activation, neuroinflammation and oxidative stress in the tauopathy mouse brain. Moreover, EF treatment induced cell-specific responses in neural cells, with neurons being more susceptible, followed by microglia and oligodendrocytes. EF also had favorable effects on synaptic protein in neurons, inflammatory response and complement signaling in microglia, and myelination in oligodendrocytes. This study provides strong evidence that EF at gamma frequency may have great potential to be a novel therapeutic intervention for P301S by attenuating neuropathology and offering neuroprotection.Supplementary InformationThe online version contains supplementary material available at 10.1186/s13195-025-01859-8.
Preclinical development of an immunoassay for the detection of TREM2: a new biomarker for Alzheimer’s disease
Scientific Reports 2025 Jul
Abstract
Alzheimer’s disease (AD) is a neurodegenerative disorder characterized by the accumulation of amyloid-β (Aβ) plaques and neurofibrillary tangles composed of hyperphosphorylated tau protein. The combination of biomarkers is crucial for AD diagnosis. The triggering receptor expressed on myeloid cells 2 (TREM2), a receptor expressed on microglia, is important in AD pathogenesis. Impairment of TREM2 function aggravates the toxic effects of amyloid plaques, and its activation has been shown to reduce Aβ burden and memory deficits. Increased levels of soluble TREM2 (sTREM2) in blood and cerebrospinal fluid is associated with AD. Therefore, TREM2 could serve as a non-invasive biomarker for AD. In this study, we developed a preclinical immunoassay to detect TREM2 for AD diagnosis. Highly sensitive and specific TREM2 antibodies were produced using the hybridoma technique. The three optimized immunoassays exhibited lower limit of quantitation (LLOQ) of 0.474, 0.807, and 0.415?ng/mL, respectively. These preclinical immunoassays showed high sensitivity and specificity. The sandwich enzyme-linked immunosorbent assay (ELISA) could potentially be used for AD diagnosis.
Structural stabilization of the intrinsically disordered SARS-CoV-2 N by binding to RNA sequences engineered from the viral genome fragment
Nature Communications 2025 Jul
Abstract
The nucleocapsid N is one of four structural proteins of the coronaviruses. Its essential role in genome encapsidation makes it a critical therapeutic target for COVID-19 and related diseases. However, the inherent disorder of full-length N hampers its structural analysis. Here, we describe a stepwise method using viral-derived RNAs to stabilize SARS-CoV-2 N for EM analysis. We identify pieces of RNA from the SARS-CoV-2 genome that promote the formation of structurally homogeneous N dimers, intermediates of assembly, and filamentous capsid-like structures. Building on these results, we engineer a symmetric RNA to stabilize N protein dimers, the building block of high-order assemblies, for EM studies. We combine domain-specific monoclonal antibodies against N with chemical cross-linking mass spectrometry to validate the spatial arrangement of the N domains within the dimer. Additionally, our cryo-EM analysis reveals novel antigenic sites on the N protein. Our findings provide insights into N protein?s architectural and antigenic principles, which can guide design of pan-coronavirus therapeutics. The authors stabilize the SARS-CoV-2 nucleocapsid (N) dimer assembly using a short RNA and chemical crosslinker for EM analysis, revealing its domain arrangement and antigenic sites to advance understanding and guide pan-coronavirus therapeutic design.
