Imaging microtubule dynamics: A new frontier in biomarker development for neurodegenerative diseases

open access: yesAlzheimer's &Dementia, Volume 21, Issue 9, September 2025.
Abstract Microtubules (MTs) are essential components of the neuronal cytoskeleton, playing key roles in intracellular transport, synaptic function, and overall neuronal integrity. Although MT dynamics and MT‐binding agents have been studied extensively, their potential as biomarkers in neurodegenerative diseases has received limited attention. Emerging

Potential Application of a Water‐Soluble Fullerene C60 Decorated with Diethylene Glycol in Treatment of Osteoarthritis

open access: yesAdvanced NanoBiomed Research, Volume 5, Issue 9, September 2025.
A new ethoxyethanol derivative of iminofullerene, F2, is synthesized and labeled with 99mTc to produce 99mTc‐F2. In vitro, compound F2 inhibits the activation of primary mouse bone marrow‐derived macrophages stimulated with lipopolysaccharide. Moreover, 99mTc‐F2 is selectively enriched in the injured joints of mice. Inflammatory macrophages play a role

Development of Carbon‐11 Labeled Pyrimidine Derivatives as Novel Positron Emission Tomography (PET) Agents Enabling Brain Sigma‐1 Receptor Imaging

open access: yesAdvanced Science, Volume 12, Issue 21, June 5, 2025.
Novel carbon‐11 labeled pyrimidine derivatives are developed as PET imaging probes for visualizing sigma‐1 receptors in the brain. [11C]CNY‐01 demonstrates superior brain uptake and binding specificity in both rodents and non‐human primates. The study reveals decreased sigma‐1 receptor expression in Alzheimer's disease, offering a promising tool for ...
