Modulatory effect of iron chelators on adenosine deaminase activity and gene expression in Trichomonas vaginalis

open access: yesMemorias do Instituto Oswaldo Cruz, 2015
Trichomonas vaginalis is a flagellate protozoan that parasitises the urogenital human tract and causes trichomoniasis. During the infection, the acquisition of nutrients, such as iron and purine and pyrimidine nucleosides, is essential for the survival ...

Enhancing antitumor immunity through the combination of cholesterolized TLR7 agonist liposomes and radiotherapy: a role for IL‐1β and the inflammasome pathway

open access: yesCancer Communications, EarlyView.
Abstract Background Radiotherapy (RT) is a key treatment modality in cancer therapy, utilizing high‐energy radiation to directly kill tumor cells. Recent research has increasingly highlighted RT's potential to indirectly enhance antitumor immunity. However, this immune activation alone often fails to generate sustained systemic antitumor responses.

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 in Inflammatory Renal Disease

open access: yesFrontiers in Physiology, 2013
Extracellular purines have a role in renal physiology and adaption to inflammation. However, inflammatory renal disease may be mediated by extracellular purines, resulting in renal injury.

Purinergic signalling links mechanical breath profile and alveolar mechanics with the pro-inflammatory innate immune response causing ventilation-induced lung injury

open access: yesPurinergic Signalling Purinergic Signalling, 2017
Severe pulmonary infection or vigorous cyclic deformation of the alveolar epithelial type I (AT I) cells by mechanical ventilation leads to massive extracellular ATP release.

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 ...

Diverse Subpopulations of Reactive Astrocytes Following Chronic Toxoplasma Infection

open access: yesGlia, EarlyView.
Toxoplasma infection results in distinct astrocyte subpopulations. Chronically labeled reactive astrocytes appear transcriptionally plastic and can regain acute inflammatory responding and naive homeostatic astrocytic gene patterns in the presence of ongoing neuroinflammation.

Potential Therapeutic Role of Purinergic Receptors in Cardiovascular Disease Mediated by SARS-CoV-2

open access: yesJournal of Immunology Research, 2020
Novel coronavirus disease 2019 (COVID-19) causes pulmonary and cardiovascular disorders and has become a worldwide emergency. Myocardial injury can be caused by direct or indirect damage, particularly mediated by a cytokine storm, a disordered immune ...

Adrenergic Control of P2Y6 Receptor‐Dependent Phagocytosis in Rodent and Human Microglia

open access: yesGlia, EarlyView.
Adrenergic signaling through ADRB2 modulates phagocytosis in microglia. Crosstalk between ADRB2 and P2Y6 receptors conserved in rodent and human microglia. ADRB2 activation inhibits both P2Y6 function and gene expression. ABSTRACT Microglia, the resident immune cells of the central nervous system (CNS), are in constant survey of their environment ...

Extracellular ATP triggers proteolysis and cytosolic Ca2+ rise in Plasmodium berghei and Plasmodium yoelii malaria parasites

open access: yesMalaria Journal, 2012
Background Plasmodium has a complex cell biology and it is essential to dissect the cell-signalling pathways underlying its survival within the host. Methods Using the fluorescence resonance energy transfer (FRET) peptide substrate Abz-AIKFFARQ-EDDnp and
