TGM2 Aggravates Acute Pancreatitis by Impairing Macrophage Efferocytosis Through Inhibition of the STAT6–GAS6 Axis

open access: yesAdvanced Science, EarlyView.
This study shows TGM2 is upregulated in AP, impairing macrophage efferocytosis by inhibiting the STAT6–GAS6 axis. The lactoferrin‐modified, ROS‐responsive LF‐LNP@si‐TGM2 targets pancreatic macrophages, silences TGM2, restores the axis, and alleviates AP.

Cryoablation Activates the cGAS–STING‐CXCL10 Axis in Macrophages to Enhance Anti‐Tumor Immunity in NSCLC

open access: yesAdvanced Science, EarlyView.
Tumor dsDNA released by cryoablation is taken up by macrophages, activating the cGAS‐STING signaling pathway. This leads to an expansion of the CXCL10+ macrophage pool and increased secretion of CXCL10, which in turn recruits CXCR3+ T cells from draining lymph nodes into the tumor microenvironment to exert anti‐tumor effects.

Azetidinylideneketenimines as a Multimodal Synthetic Platform: Coordination Chemistry and Cycloaddition‐Triggered Transformations

open access: yesAngewandte Chemie, EarlyView.
Cross‐coupling/homologation sequence between a stable three‐membered‐ring carbene and isocyanides enables facile and rapid access to novel methyleneketenimines and the first bis(methyleneketenimine). Reactivity studies gave rise to the first methyleneketenimine‐transition metal complexes, unique multimodal reactivity ranging from CO2, isocyanate ...

Differences in neurotropism and neurotoxicity among retrograde viral tracers

open access: yesMolecular Neurodegeneration, 2019
Background Neurotropic virus-based tracers have been extensively applied in mapping and manipulation of neural circuits. However, their neurotropic and neurotoxic properties remain to be fully characterized.

Sub‐Unit‐Cell Logic Governs Transport in TPMS Architectures

open access: yesAdvanced Science, EarlyView.
ABSTRACT Next‐generation energy, thermal, and chemical systems require architectures capable of highly efficient transport across multiple length scales. Triply periodic minimal surfaces (TPMS), first conceptualized in 1865, offer inherently scalable geometries with exceptional transport potential, yet mechanistic links between topology and performance

Total Synthesis of the Spirocyclic Bis‐Indole Alkaloid (−)‐Owerreine via a [4+2] Annulation

open access: yesAngewandte Chemie, EarlyView.
The total synthesis of the bis‐indole alkaloid (−)‐owerreine has been accomplished by a diastereoselective [4+2] annulation between an enamine and an α,β−unsaturated indolenine precursor to form the 3‐spirocyclic tetrahydropyridine linkage of the natural product. DFT calculations allow an understanding of the mechanism of the key annulation.

Capacity of Retro-Information Channels [PDF]

open access: yes, 1999
In this paper we investigate how retro-information is possible in a non unitary universe. In particular we give estimate of asymptotic capacity of retro-information channels in parallel or in series.

Enzyme‐Activated MRI for In Vivo Glucose Imaging via a Biodegradable Chromium Nanoprobe

open access: yesAdvanced Science, EarlyView.
Enzyme‐activated MRI (eaMRI) using a biodegradable CrGOx@Lip nanoprobe enables glucose‐specific imaging in vivo. GOx catalyzes glucose oxidation, triggering in situ formation of paramagnetic chromium gluconate and amplifying T1. This radiation‐free strategy maps tumor glucose uptake via the Warburg‐effect, quantifies hepatic glucose accumulation in ...

Loss of hepatic SMLR1 causes hepatosteatosis and protects against atherosclerosis due to decreased hepatic VLDL secretion

open access: yesHepatology, EarlyView., 2022
The role of SMLR1 in lipid metabolism (high fat + cholesterol diet in mice) Abstract Background and Aims The assembly and secretion of VLDL from the liver, a pathway that affects hepatic and plasma lipids, remains incompletely understood. We set out to identify players in the VLDL biogenesis pathway by identifying genes that are co‐expressed with the ...
