Purinergic signalling is involved in the malaria parasite Plasmodium falciparum invasion to red blood cells

open access: yes, 2010
Plasmodium falciparum, the most important etiological agent of human malaria, is endowed with a highly complex cell cycle that is essential for its successful replication within the host.

Purinergic signaling in kidney disease [PDF]

open access: yesKidney International, 2017
Nucleotides are key subunits for nucleic acids and provide energy for intracellular metabolism. They can also be released from cells to act physiologically as extracellular messengers or pathologically as danger signals. Extracellular nucleotides stimulate membrane receptors in the P2 and P1 family. P2X are ATP-activated cation channels; P2Y and P1 are

Clock Genes Regulate Ca2+ Signaling and Mitochondrial Bioenergetics to Inhibit Sjögren Disease

open access: yesArthritis &Rheumatology, EarlyView.
Objective Although Ca2+ signaling and metabolism have been identified as key determinants for the development of Sjögren disease (SjD), the intricate connection between them and salivary gland physiology remains poorly understood. Methods Fluorescence‐based Ca2+ imaging, RNA sequencing, and mitochondrial activity were used to investigate the effects of

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1059-1080, April 2025.
Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...

Purinergic Signalling: Pathophysiological Roles

open access: yesJapanese Journal of Pharmacology, 1998
In this review, after a summary of the history and current status of the receptors involved in purinergic signalling, we focus on the distribution and physiological roles of purines and pyrimidines in both short-term events such as neurotransmission, exocrine and endocrine secretion and regulation of immune cell function, and long-term events such as ...

Inconsistent Transcriptomic Responses to Hexabromocyclododecane in Japanese Quail: A Comparative Analysis of Results From Four Different Study Designs

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Abstract Efforts to use transcriptomics for toxicity testing have classically relied on the assumption that chemicals consistently produce characteristic transcriptomic signatures that are reflective of their mechanism of action. However, the degree to which transcriptomic responses are conserved across different test methodologies has seldom been ...

Function‐centered back‐tracing refines obesity‐associated gut microbiome signals beyond abundance‐based profiling

open access: yesiMetaOmics, EarlyView.
By integrating taxonomic and functional profiling of 1543 adult gut metagenomes, this study identified microbial taxa and enzymatic functions associated with increasing Body Mass Index. Function‐centered taxonomic back‐tracing of branched‐chain amino acid transaminase, nucleotide diphosphatase, and phosphatidylserine decarboxylase revealed only limited

Purinergic and glutamatergic interactions in the hypothalamic paraventricular nucleus modulate sympathetic outflow

open access: yes, 2013
P2X receptors are expressed on ventrolateral medulla projecting paraventricular nucleus (PVN) neurons. Here, we investigate the role of adenosine 5′-triphosphate (ATP) in modulating sympathetic nerve activity (SNA) at the level of the PVN.

Beneficial effect of electroacupuncture on the distribution of foreign substances in the brain of rats developing depression-like behavior

open access: yesIBRO Neuroscience Reports, 2023
We used low and high molecular weight fluorescence tracers to investigate the entry of foreign solutes into the brain parenchyma and their exit from it by the glymphatic system, during experimentally induced depressive-like behavior in rats.

Monocyte inflammation and adaptive immune dysfunction in severe Klebsiella pneumoniae pneumonia

open access: yesiMeta, EarlyView.
Severe Klebsiella pneumoniae pneumonia combines intense inflammation with failure to control infection, yet the cellular basis is unclear. Using a severity‐focused single‐cell atlas of 708,894 peripheral blood mononuclear cells from 100 individuals, complemented by plasma protein measurements and flow cytometry, we show that disease severity redirects ...
