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

open access: yesAdvanced Science, EarlyView.
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 ...

M6A Modified miR‐31‐5p Suppresses M1 Macrophage Polarization and Autoimmune Dry Eye by Targeting P2RX7

open access: yesAdvanced Science, EarlyView.
The upregulation of FTO in autoimmune dry eye suppresses the recognition of pri‐miR‐31 by DGCR8, thereby inhibiting the maturation of miR‐31‐5p and reducing its inhibitory effect on the target gene P2RX7. The activation of P2RX7 subsequently triggers the p38 MAPK signaling pathway and increases the level of M1‐related genes, thus exacerbating the ...

Exploiting the Unique Properties of Lanthanide Complexes as FRET Probes: from Quantitation to Protein Dynamics

open access: yesAnalysis &Sensing, Volume 3, Issue 1, January 2023., 2023
Lanthanide complexes are ideal donors for FRET (Förster resonance energy transfer) assays with a variety of applications from easy‐to‐use quantitation of proteins to sophisticated experiments giving real‐time information on the movement of proteins. This Review article introduces the principles of using such assays before surveying the full scope of ...
