PQQ Supplementation and SARS-CoV-2 Spike Protein-Induced Heart Inflammation

Natural Product Communications, 2022
SARS-CoV-2 spike protein-induced heart inflammation may originate from either COVID-19 infection or the administration of COVID-19 mRNA vaccines. As pyrroloquinoline quinone (PQQ) is a scavenger of free radicals, redox cofactor, and antioxidant which ...

Source‐Independent Enrichment of Light Lanthanides: Microbial Mobilization, Selective Uptake, and Intracellular Storage

Environmental Microbiology, Volume 28, Issue 9, September 2026.
Only light lanthanides facilitate lanthanide‐dependent methylotrophy. In Beijerinckiaceae bacterium RH AL1, light lanthanides are enriched from diverse sources, including poorly soluble minerals, through a multilayered process involving mobilisation, selective uptake, and intracellular periplasmic storage.

A Mechanism‐Based Framework for Anti‐Aging Strategies: From Metabolic Regulation to Senotherapy and Stem Cell‐Based Interventions

Aging Cell, Volume 25, Issue 9, September 2026.
The aging of the human body is a complex process driven by multiple contributing factors. Based on their underlying mechanisms, current anti‐aging interventions can be classified into six primary categories. This paper summarizes the most promising anti‐aging strategies within each class. ABSTRACT The global prevalence of aging and age‐related diseases

Simple immobilization of pyrroloquinoline quinone on few-walled carbon nanotubes [PDF]

, 2010
Pyrroloquinoline quinone (PQQ) was immobilized on glassy-carbon electrodes (GCE) modified with single-walled carbon nanotubes (SWCNT), few-walled carbon nanotubes (FWCNT) and carbon black (Vulcan XC72R). Modified electrodes were prepared by drop-casting.

A Two-component Protease in Methylorubrum Extorquens with High Activity Toward the Peptide Precursor of the Redox Cofactor Pyrroloquinoline Quinone [PDF]

, 2019
Pyrroloquinoline quinone is a prominent redox cofactor in many prokaryotes, produced from a ribosomally synthesized and post-translationally modified peptide PqqA via a pathway comprising four conserved proteins PqqB–E. These four proteins are now fairly
