Humoral cross-reactivity towards SARS-CoV-2 in young children with acute respiratory infection with low-pathogenicity coronaviruses

Journal of Clinical Virology Plus, 2022
Background: SARS-CoV-2 infection in children frequently leads to only asymptomatic and mild infections. It has been suggested that frequent infections due to low-pathogenicity coronaviruses in children, impart immunity against SARS-CoV-2 in this age ...

Self‐Sterilizing Face Mask Employing Enzymatic Power Generation

Advanced Materials Technologies, EarlyView.
Electric face mask with flexible biofuel cell integration for on‐the‐go sterilization is developed utilizing ethanol oxidation via alcohol dehydrogenase, and oxygen reduction via bilirubin oxidase. Modified face mask exhibited bacterial death rates of 40–60% at only 20 µA of electric current, easily generated by the biofuel cell continuously over hours

Roles of flavonoids against coronavirus infection

Chemico-Biological Interactions, 2020
In terms of public health, the 21st century has been characterized by coronavirus pandemics: in 2002-03 the virus SARS-CoV caused SARS; in 2012 MERS-CoV emerged and in 2019 a new human betacoronavirus strain, called SARS-CoV-2, caused the unprecedented COVID-19 outbreak.

Revealing Cell‐Free Mitochondrial DNA Breakage Patterns as Novel Biomarkers for Sepsis

Advanced Science, EarlyView.
Uncovering distinct plasma cfmtDNA breakage patterns opens new frontiers for early sepsis detection and prognosis. Unique cleavage hotspots in RNR2 and COX2 regions outperform traditional biomarkers, while mechanistic insights suggest bacterial endonuclease involvement.

NSP7 Molecular Degrader Attenuates Coronaviral Infection Through the β‐TrCP1/FBXO5 Axis

Advanced Science, EarlyView.
Host E3 ligase FBXO5 as a key regulator that promotes K48‐linked ubiquitination and proteasomal degradation of SARS‐CoV‐2 NSP7, thereby suppressing viral replication. NSP7 ubiquitination is co‐regulated by β‐TrCP1 and TAF1. Small molecule BC24877 disrupts β‐TrCP1‐mediated degradation of FBXO5, stabilizing FBXO5 and enhancing NSP7 clearance ...

PFKFB2‐Driven Glycolysis Promotes Dendritic Cell Maturation and Exacerbates Acute Lung Injury

Advanced Science, EarlyView.
Paraquat (PQ) or lipopolysaccharide (LPS) exposure activates the HIF‐1α–PFKFB2 pathway, driving glycolysis in dendritic cells (DCs). This metabolic shift enhances DC maturation and immune activation, exacerbating acute lung injury (ALI). This study demonstrates that PFKFB2‐driven glycolytic reprogramming in DCs plays a critical role in the pathogenesis
