Pyrroloquinoline Quinone Reprograms the Single-Cell Landscape of Immune Aging in Hematopoietic Immune System. [PDF]

open access: yesAging Cell
This study demonstrates that aging induces oxidative stress and inflammation in the hematopoietic immune system, resulting in immune homeostasis dysfunction, including alterations in B cells and hematopoietic stem cells, senescent cells (SnCs) accumulation, and senescence‐associated secretory phenotypes (SASPs) production. Notably, the study highlights

Pyrroloquinoline-Quinone Is More Than an Antioxidant: A Vitamin-like Accessory Factor Important in Health and Disease Prevention

open access: yesBiomolecules, 2021
Pyrroloquinoline quinone (PQQ) is associated with biological processes such as mitochondriogenesis, reproduction, growth, and aging. In addition, PQQ attenuates clinically relevant dysfunctions (e.g., those associated with ischemia, inflammation and ...

Discovery of a eukaryotic pyrroloquinoline quinone-dependent oxidoreductase belonging to a new auxiliary activity family in the database of carbohydrate-active enzymes. [PDF]

open access: yesPLoS ONE, 2014
Pyrroloquinoline quinone (PQQ) is a redox cofactor utilized by a number of prokaryotic dehydrogenases. Not all prokaryotic organisms are capable of synthesizing PQQ, even though it plays important roles in the growth and development of many organisms ...

PQQ-linked extracellular glucose oxidation and chemotaxis towards this cofactor in rhizobia [PDF]

open access: yesFEMS Microbiology Letters, 1996
The presence of the pyrroloquinoline quinone (PQQ)-dependent glucose dehydrogenase in several strains of different Rhizobium species and of Bradyrhizobium japonicum was investigated. It was found that most strains were only able to synthesize the apo-enzyme, whereas in three strains, Rhizobium meliloti 102F34 and Bradyrhizobium japonicum strains ...

Effects of pyrroloquinoline quinone on noise-induced and age-related hearing loss in mice

open access: yesScientific Reports, 2022
We investigated whether the oxidoreductase cofactor pyrroloquinoline quinone (PQQ) prevents noise-induced and age-related hearing loss (NIHL and ARHL) in mice.

Pyrroloquinoline quinone (PQQ) protects mitochondrial function of HEI-OC1 cells under premature senescence

open access: yesnpj Aging, 2022
The aim of this study was to investigate the effects of pyrroloquinoline quinone (PQQ), an oxidoreductase cofactor, on the H 2 O 2 -induced premature senescence model in HEI-OC1 auditory cells and to elucidate its mechanism of action in vitro. Cells were

High-affinity PQQ import is widespread in Gram-negative bacteria. [PDF]

open access: yesSci Adv
PQQ is a soluble redox cofactor used by diverse bacteria to oxidise fuel compounds as a source of electrons for the respiratory chain. Many Gram-negative bacteria that encode PQQ-dependent enzymes do not possess the biosynthetic machinery for its ...

Pyrroloquinoline Quinone Administration Alleviates Allergic Airway Inflammation in Mice by Regulating the JAK-STAT Signaling Pathway

open access: yesMediators of Inflammation, 2022
The current asthma therapies are inadequate for many patients with severe asthma. Pyrroloquinoline quinone (PQQ) is a naturally-occurring redox cofactor and nutrient that can exert a multitude of physiological effects, including anti-inflammatory and ...
