Reversal of neuronal tau pathology via adiponectin receptor activation.
Commun Biol
January 2025

Changes in brain mitochondrial metabolism are coincident with functional decline; however, direct links between the two have not been established. Here, we show that mitochondrial targeting via the adiponectin receptor activator AdipoRon (AR) clears neurofibrillary tangles (NFTs) and rescues neuronal tauopathy-associated defects. AR reduced levels of phospho-tau and lowered NFT burden by a mechanism involving the energy-sensing kinase AMPK and the growth-sensing kinase GSK3b.

In higher plants, sugars are the primary products of photosynthesis, where CO is converted into organic carbon within the mesophyll cells of leaves. These sugars serve as a critical source of carbon skeletons for the biosynthesis of essential cellular compounds, energy production, and as osmotic and signaling molecules. Plant sugar transporter proteins play a key role in facilitating the long-distance translocation of sugars from source to sink organs, thereby controlling their distribution and accumulation across the plant.

Pemphigoid nodularis and prurigo nodularis have similar clinicopathological features and are difficult to distinguish. Enzyme-linked immunosorbent assays (ELISA) and direct/indirect immunofluorescence can support the diagnosis of pemphigoid nodularis, but sometimes show contradictory results or are unavailable. We aimed to develop a practical method for differentiating between pemphigoid nodularis and prurigo nodularis.

Background: X chromosome inactivation (XCI) is a female-specific process in which one X chromosome is silenced to balance X-linked gene expression between the sexes. XCI is initiated in early development by upregulation of the lncRNA Xist on the future inactive X (Xi). A subset of X-linked genes escape silencing and thus have higher expression in females, suggesting female-specific functions.

Jiujiang Clinical Precision Medicine Research Center, Jiujiang, Jiangxi, China.
Background: Adenosine deaminase action on RNA 1 (ADAR1) can convert the adenosine in double-stranded RNA (dsRNA) molecules into inosine in a process known as A-to-I RNA editing. ADAR1 regulates gene expression output by interacting with RNA and other proteins; plays important roles in development, including growth; and is linked to innate immunity, tumors, and central nervous system (CNS) diseases.
Results: In recent years, the role of ADAR1 in tumors has been widely discussed, but its role in CNS diseases has not been reviewed.
