Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract

Advanced Robotics Research, EarlyView.
We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a

Establishing In Vitro Screening Protocols Based on Phenotypic Plasticity of Amaranthus dubius and Galinsoga parviflora Seeds for Drought, Salinity, and Heat Tolerance

International Journal of Plant Biology
The vulnerability of commercial crops under a changing climate has led scientists to consider wild crop species as alternative food sources. The aim of this study was to identify plastic physiological and morphological traits that could be used to in ...

RNF213 Is an Interferon‐Stimulated Gene That Targets Influenza A Virus NP and Activates MDA5 to Restrict Infection

Advanced Science, EarlyView.
RNF213 is characterized as a dual‐functional antiviral effector. It directly mediates the degradation of the influenza A virus nucleoprotein (NP) while simultaneously activating the MDA5‐mediated innate immune signaling pathway. This coordinated response establishes a powerful host defense system against viral infection. ABSTRACT Influenza A virus (IAV)

RETREG1‐Mediated Reticulophagy is Essential for Dendritic Cell Maturation and Function in Sepsis

Advanced Science, EarlyView.
Reticulophagy regulator 1 (RETREG1) maintains dendritic cell (DC) maturation and function in early sepsis. Mechanistically, activating transcription factor 6 (ATF6) acts as a direct transcription factor regulating RETREG1 expression in response to sepsis‐induced endoplasmic reticulum (ER) stress.

Marburg Virus Glycoprotein Is a Remarkable Virulent Factor Linked to Hemorrhagic Pathology: Evidence from Multimodal Experimental Systems

Advanced Science, EarlyView.
By integrating data from in vitro, ex vivo, and in vivo models, our research identifies the MARV glycoprotein as a remarkable hemorrhagic factor, filling a major gap in this important field. It also provides practical experimental tools for the basic research on viral pathogenesis and applied research aimed at antiviral intervention for hemorrhagic ...

DCAF13 Safeguards Hematopoietic Stem Cells via RRS1‐Regulated Ribosome Biogenesis

Advanced Science, EarlyView.
This study establishes DCAF13 as an essential regulator for hematopoietic stem cell (HSC) function. Its deletion in mice causes lethal pancytopenia and HSC depletion. Mechanistically, DCAF13 interacts with RRS1 and mediates its non‐degradative K27‐linked ubiquitination, thereby stabilizing RRS1 to maintain ribosome biogenesis and protein translation ...
