Interaction between host G3BP and viral nucleocapsid protein regulates SARS-CoV-2 replication and pathogenicity

open access: yesCell Reports
Summary: G3BP1/2 are paralogous proteins that promote stress granule formation in response to cellular stresses, including viral infection. The nucleocapsid (N) protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) inhibits stress ...

Stress Granule-Inducing Eukaryotic Translation Initiation Factor 4A Inhibitors Block Influenza A Virus Replication

open access: yesViruses, 2017
Eukaryotic translation initiation factor 4A (eIF4A) is a helicase that facilitates assembly of the translation preinitiation complex by unwinding structured mRNA 5′ untranslated regions. Pateamine A (PatA) and silvestrol are natural products that disrupt

Platelet Rubicon Bidirectional Regulation of GPVI and Integrin αIIbβ3 Signaling Mitigates Stroke Infarction Without Compromising Hemostasis

open access: yesAdvanced Science, EarlyView.
This study identifies Rubicon as a key platelet protein that bidirectionally regulates GPVI and integrin αIIbβ3 signaling. Platelet Rubicon protects against cerebral ischemia‐reperfusion injury by limiting infarction without increasing hemorrhage.

TREM2 Drives Neutrophil Extracellular Traps‐Induced Dendritic Cell Maturation and Contributes to Lupus Progression

open access: yesAdvanced Science, EarlyView.
TREM2 recognizes NETs‐derived MPO to promote DC maturation and antigen presentation, thereby exacerbating the autoimmune response in SLE. Mechanistically, TREM2 activation triggers the DAP12/SYK/ERK cascade and enhances NETs internalization by DCs, which in turn activates the cGAS/STING signaling pathway.

Retinoic Acid Reprograms Mast Cells Toward a Proinflammatory State to Enhance Antitumor Immunity

open access: yesAdvanced Science, EarlyView.
Proinflammatory mast cells represent an MHC‐IIhigh, cytokine‐producing mast cell subset associated with improved survival and enhanced responses to anti‐PD‐1 therapy. Retinoic acid drives their polarization, enabling antigen uptake and presentation, and T cell recruitment and activation, collectively promoting adaptive anti‐tumor immunity.

Wedelolactone, a Novel TLR2 Agonist, Promotes Neutrophil Differentiation and Ameliorates Neutropenia: A Multi‐Omics Approach to Unravel the Mechanism

open access: yesAdvanced Science, EarlyView.
Wedelolactone (WED), a natural TLR2 agonist, promotes neutrophil differentiation and enhances bactericidal function, offering a potential therapeutic strategy for neutropenia. Using a multi‐omics approach, this study reveals that WED activates the TLR2/MEK/ERK pathway, upregulating key transcription factors (PU.1, CEBPβ) to drive neutrophil development.

Magnetic flux emergence in granular convection: Radiative MHD simulations and observational signatures

open access: yes, 2007
We study the emergence of magnetic flux from the near-surface layers of the solar convection zone into the photosphere. To model magnetic flux emergence, we carried out a set of numerical radiative magnetohydrodynamics simulations.

Heat Stress Modulates WDR5‐Mediated H3K4me3 Modification to Induce Melanogenesis via Activating CX3CL1/CX3CR1 Axis

open access: yesAdvanced Science, EarlyView.
This study elucidates the mechanism by which heat stress regulates skin pigmentation: heat stress upregulates CX3CL1 through the MYC‐WDR5‐H3K4me3 axis, thereby activating the CX3CL1/CX3CR1‐JNK signaling pathway and ultimately promoting melanogenesis. These findings provide novel potential therapeutic targets for pigmentary skin disorders.

Red Blood Cells Internalize Extracellular DNA via Apoptotic Bodies with Clinical Relevance to Cancer Patients

open access: yesAdvanced Science, EarlyView.
Mature red blood cells (RBCs) can capture extracellular DNA, with short fragments homologous to cfDNA. This uptake is mediated by apoptotic bodies, which induce RBC oxidative stress, deformation, and accelerated in vivo clearance. The rbcDNA abundance correlates with tumor burden and therapeutic response, highlighting its potential as a liquid biopsy ...
