Astrocytic adenosine signaling is disrupted in neurodegeneration, leading to sleep-wake imbalances MEDIUM
Science · 2019 · PMID:30679341
ABSTRACT

Species richness of marine mammals and birds is highest in cold, temperate seas-a conspicuous exception to the general latitudinal gradient of decreasing diversity from the tropics to the poles. We compiled a comprehensive dataset for 998 species of sharks, fish, reptiles, mammals, and birds to identify and quantify inverse latitudinal gradients in diversity, and derived a theory to explain these patterns. We found that richness, phylogenetic diversity, and abundance of marine predators diverge systematically with thermoregulatory strategy and water temperature, reflecting metabolic differences between endotherms and ectotherms that drive trophic and competitive interactions. Spatial patterns of foraging support theoretical predictions, with total prey consumption by mammals increasing by a factor of 80 from the equator to the poles after controlling for productivity.

A2A receptor activation promotes astrocytic glycogen breakdown and lactate production for neuronal support MEDIUM
J Neurosci · 2015 · PMID:25904789
ABSTRACT

Hair cells of the inner ear are essential for hearing and balance. As a consequence, pathogenic variants in genes specifically expressed in hair cells often cause hereditary deafness. Hair cells are few in number and not easily isolated from the adjacent supporting cells, so the biochemistry and molecular biology of hair cells can be difficult to study. To study gene expression in hair cells, we developed a protocol for hair cell isolation by FACS. With nearly pure hair cells and surrounding cells, from cochlea and utricle and from E16 to P7, we performed a comprehensive cell type-specific RNA-Seq study of gene expression during mouse inner ear development. Expression profiling revealed new hair cell genes with distinct expression patterns: some are specific for vestibular hair cells, others for cochlear hair cells, and some are expressed just before or after maturation of mechanosensitivity. We found that many of the known hereditary deafness genes are much more highly expressed in ha

Sleep deprivation alters astrocytic adenosine metabolism and impairs neuronal energy supply MEDIUM
PLoS Comput Biol · 2012 · PMID:23300412
ABSTRACT

Differences between individual human genomes, or between human and cancer genomes, range in scale from single nucleotide variants (SNVs) through intermediate and large-scale duplications, deletions, and rearrangements of genomic segments. The latter class, called structural variants (SVs), have received considerable attention in the past several years as they are a previously under appreciated source of variation in human genomes. Much of this recent attention is the result of the availability of higher-resolution technologies for measuring these variants, including both microarray-based techniques, and more recently, high-throughput DNA sequencing. We describe the genomic technologies and computational techniques currently used to measure SVs, focusing on applications in human and cancer genomics.

Sepsis expands a CD39(+) plasmablast population that promotes immunosuppression via adenosine-mediated inhibition of macrophage antimicrobial activity.
Immunity · 2021 · PMID:34473957
ABSTRACT

Sepsis results in elevated adenosine in circulation. Extracellular adenosine triggers immunosuppressive signaling via the A2a receptor (A2aR). Sepsis survivors develop persistent immunosuppression with increased risk of recurrent infections. We utilized the cecal ligation and puncture (CLP) model of sepsis and subsequent infection to assess the role of adenosine in post-sepsis immune suppression. A2aR-deficient mice showed improved resistance to post-sepsis infections. Sepsis expanded a subset of CD39hi B cells and elevated extracellular adenosine, which was absent in mice lacking CD39-expressing B cells. Sepsis-surviving B cell-deficient mice were more resistant to secondary infections. Mechanistically, metabolic reprogramming of septic B cells increased production of ATP, which was converted into adenosine by CD39 on plasmablasts. Adenosine signaling via A2aR impaired macrophage bactericidal activity and enhanced interleukin-10 production. Septic individuals exhibited expanded CD39hi

Endothelial adenosine receptor 2A loss alleviates diabetic vascular calcification by blocking CREB1-SNAI1-driven EndMT.
Pharmacol Res · 2025 · PMID:41067595
ABSTRACT

Vascular calcification (VC), a common complication associated with diabetes mellitus (DM), substantially increases the risk of cardiovascular diseases and is associated with elevated mortality in individuals with DM. Endothelial-to-mesenchymal transition (EndMT) imparts phenotypic plasticity to vascular endothelial cells (VECs), granting them the potential for osteogenic differentiation, which is a crucial mechanism in regulating VC. Notably, adenosine-ADORA2A-mediated endothelial dysfunction plays a pivotal regulatory role in cardiovascular diseases. However, the specific role of endothelial ADORA2A in diabetic VC remains to be elucidated. In this study, we found that ADORA2A was upregulated in the endothelium of diabetic mice and cultured human aortic endothelial cells (HAECs) with high glucose treatment. Deletion of endothelial Adora2a or pharmacologic inhibition of ADORA2A with KW6002 attenuated EndMT, osteogenic differentiation, and calcium deposit in diabetic aortas of Ins2Akita/

Targeting adenosine 2A receptor signaling suppresses vascular calcification by restraining smooth muscle osteogenic differentiation.
Pharmacol Res · 2025 · PMID:41201506
ABSTRACT

Vascular calcification (VC) is a major contributor to cardiovascular morbidity and mortality, particularly in patients with chronic kidney disease (CKD). Adenosine 2 A receptor (ADORA2A) is highly expressed in vascular cells and implicated in cardiovascular disease; however, its specific role in VC pathogenesis remains unclear. Here, we investigated the role of ADORA2A using in vitro (vascular smooth muscle cells; VSMCs), ex vivo (mouse aortic rings), and in vivo (5/6th nephrectomy with high phosphate and cholecalciferol) models of VC. The ADORA2A expression was significantly upregulated in calcified human and murine aortic tissues, as well as in VSMCs, under osteogenic conditions. Genetic deletion of Adora2a (global or VSMC-specific) or pharmacological antagonism of ADORA2A markedly attenuated aortic calcification and the expression of osteogenic markers in vivo. Consistent findings were observed in in vitro and ex vivo models. Conversely, ADORA2A overexpression exacerbated the osteog

Sci Signal · 2025 · PMID:40986641
ABSTRACT

Metabolic reprogramming controls protective and pathogenic T helper 17 (TH17) cell responses. When naïve T cells are differentiated into TH17 cells in vitro, the presence of the cytokine activin A promotes their maturation into a nonpathogenic state. Here, we found that nonpathogenic TH17 cells induced by activin A displayed reduced aerobic glycolysis and increased oxidative phosphorylation (OXPHOS). In response to activin A, signaling through the adenosine A2A receptor (A2AR) and AMP-activated protein kinase (AMPK) enhanced OXPHOS and reprogrammed pathogenic TH17 cells toward nonpathogenic states that did not induce central nervous system autoimmunity in a mouse model of multiple sclerosis. In pathogenic TH17 cells, the transcriptional coactivator p300/CBP-associated factor (PCAF) increased acetylation at histone 3 Lys9 (H3K9ac) of genes involved in aerobic glycolysis and TH17 pathogenic programs. In contrast, in nonpathogenic activin A-treated TH17 cells, AMPK signaling suppressed PC

Transcriptional control of pancreatic cancer immunosuppression by metabolic enzyme CD73 in a tumor-autonomous and -autocrine manner.
Nat Commun · 2023 · PMID:37291128
ABSTRACT

Cancer cell metabolism contributes to the establishment of an immunosuppressive tumor microenvironment. Aberrant expression of CD73, a critical enzyme in ATP metabolism, on the cell surface results in the extracellular accumulation of adenosine, which exhibits direct inhibitory effects on tumor-infiltrating lymphocytes. However, little is known about the influence of CD73 on negative immune regulation-associated signaling molecules and transduction pathways inside tumor cells. This study aims to demonstrate the moonlighting functions of CD73 in immunosuppression in pancreatic cancer, an ideal model characterized by complex crosstalk among cancer metabolism, immune microenvironment, and immunotherapeutic resistance. The synergistic effect of CD73-specific drugs in combination with immune checkpoint blockade is observed in multiple pancreatic cancer models. Cytometry by time-of-flight analysis shows that CD73 inhibition reduces tumor-infiltrating Tregs in pancreatic cancer. Tumor cell-au

Parthenolide inhibits methamphetamine-induced depressive-like behavior by targeting ADORA2A. MEDIUM
Phytomedicine · 2026 · PMID:41795299
ABSTRACT

BACKGROUND: Methamphetamine (METH) abuse often results in persistent depressive-like behaviors, while current treatments show limited efficacy. Parthenolide, a natural compound with neuroprotective and anti-inflammatory properties, has shown benefits in several CNS disorders, but its role in METH-induced depression remains unknown. PURPOSE: This study aimed to evaluate whether parthenolide alleviates METH-induced depressive-like behaviors and to identify key brain regions and molecular targets involved. METHODS: Mice were administered METH using a 15-day escalating regimen and treated with parthenolide. Behavioral tests, histopathology, Nissl staining, and c-Fos mapping were conducted to assess neural alterations. Metabolomics and network pharmacology were used to predict targets, followed by molecular docking, dynamics simulations, cellular thermal shift assay, and pharmacological modulation for validation. RESULTS: Parthenolide significantly improved METH-induced depressive-like beha

De novo purine synthesis reprograms the macrophage inflammatory response and the immune response in sepsis. MEDIUM
Res Sq · 2026 · PMID:41756441
ABSTRACT

Sepsis is characterized by profound immunometabolic dysregulation, yet the role of purine precursor synthesis in immune reprogramming remains poorly defined. Intracellular purine nucleotides, such as ATP, are generated by de novo synthesis, which assembles purinosomes to build inosine monophosphate (IMP) from small precursors, or by the salvage pathway, which recycles purine bases such as hypoxanthine. Here, we investigated how these pathways regulate macrophage activation and host responses in sepsis. Silencing the de novo purine enzyme glycinamide ribonucleotide transformylase (GART) in LPS-stimulated macrophages induced marked transcriptomic remodeling, suppressing anti-inflammatory mediators, including IL-10 and TIMP-1, while increasing TNF-α. These effects were reversed by hypoxanthine supplementation, indicating rescue through salvage. Similar findings were observed with silencing of phosphoribosyl pyrophosphate amidotransferase (PPAT) or pharmacological GART inhibition with azas

Surface d-Band Modulation via Biodirected Mineralization Enables Nanoenzymes to Inhibit Radiation-Induced T-Cell Exhaustion and Potentiate Immunoradiotherapy.
ACS Nano · 2025 · PMID:41073355
ABSTRACT

Immunoradiotherapy (iRT) has emerged as a promising strategy for liver hepatocellular carcinoma (LIHC) treatment to synergistically activate both localized antitumor immunity and systemic immune responses. However, radiation will aggravate LIHC hypoxia, resulting in an adenosine metabolism level elevation, which promotes the differentiation of T cells into terminally exhausted phenotypes and weakens the efficacy of immunotherapy. To overcome this challenge, we engineered a nanocatalytic probiotic-based radiation-metabolic modulator, in which Escherichia coli Nissle 1917 (EcN) was programmed to in situ synthesize gold-palladium bimetallic nanocatalysts (EcNcGP) via biodirected mineralization. Guided by lattice mismatch and interfacial strain engineering, engineered EcN orchestrates the epitaxial assembly of Au atoms on Pd nanoclusters, yielding a precisely strain-tuned heterostructure with a modulated d-band electronic structure. This architectural design optimizes oxygen intermediate a

ABSTRACT

Although 7-methylxanthine, a nonselective adenosine receptor (AdoRs) antagonist, suppresses myopia, the specific receptor subtype and target tissue involved remain unclear. This study aimed to investigate whether the AdoRA2a subtype plays a critical role in the regulation of myopia progression. Monocular form deprivation myopia (FDM) was induced in mice to measure retinal concentrations of adenosine and its synthetic enzymes (CD39/CD73).

ABSTRACT

The adenosine A2A receptor (A2AR) is a promising therapeutic target for depression, as evidenced by the notable antidepressant-like efficacy of its antagonists. However, conventional screening methods for A2AR ligands are hampered by low throughput and operational complexity. To address this, we developed a high-throughput screening (HTS) strategy based on the detection of calcium flow fluorescence signals in engineered HEK-ADORA2A cells.

ABSTRACT

Ergogenic aids have long attracted scientific interest for their potential to enhance neuromuscular performance, with caffeine being among the most extensively studied. While traditionally attributed to peripheral actions on skeletal muscle, accumulating evidence indicates that, at physiological doses, caffeine's ergogenic effects are predominantly mediated by antagonism of central adenosine receptors. This antagonism leads to increased arousal, reduced inhibitory neuromodulation, enhanced corti

ABSTRACT

More than 3000 per- and polyfluoroalkyl substances (PFASs) are, or have been, on the global market, yet most research and regulation continues to focus on a limited selection of rather well-known long-chain PFASs, particularly perfluorooctanesulfonate (PFOS), perfluorooctanoic acid (PFOA) and their precursors. Continuing to overlook the vast majority of other PFASs is a major concern for society. We provide recommendations for how to proceed with research and cooperation to tackle the vast number of PFASs on the market and in the environment.

A2A receptor antagonists (like caffeine) improve cognitive function and reduce AD risk MEDIUM
J Alzheimers Dis · 2010 · PMID:20164566
ABSTRACT

Caffeine causes most of its biological effects via antagonizing all types of adenosine receptors (ARs): A1, A2A, A3, and A2B and, as does adenosine, exerts effects on neurons and glial cells of all brain areas. In consequence, caffeine, when acting as an AR antagonist, is doing the opposite of activation of adenosine receptors due to removal of endogenous adenosinergic tonus. Besides AR antagonism, xanthines, including caffeine, have other biological actions: they inhibit phosphodiesterases (PDEs) (e.g., PDE1, PDE4, PDE5), promote calcium release from intracellular stores, and interfere with GABA-A receptors. Caffeine, through antagonism of ARs, affects brain functions such as sleep, cognition, learning, and memory, and modifies brain dysfunctions and diseases: Alzheimer's disease, Parkinson's disease, Huntington's disease, Epilepsy, Pain/Migraine, Depression, Schizophrenia. In conclusion, targeting approaches that involve ARs will enhance the possibilities to correct brain dysfunction

Excessive astrocytic activation can be neurotoxic regardless of energy provision MEDIUM
Science · 2019 · PMID:31488706
ABSTRACT

Caenorhabditis elegans is an animal with few cells but a wide diversity of cell types. In this study, we characterize the molecular basis for their specification by profiling the transcriptomes of 86,024 single embryonic cells. We identify 502 terminal and preterminal cell types, mapping most single-cell transcriptomes to their exact position in C. elegans' invariant lineage. Using these annotations, we find that (i) the correlation between a cell's lineage and its transcriptome increases from middle to late gastrulation, then falls substantially as cells in the nervous system and pharynx adopt their terminal fates; (ii) multilineage priming contributes to the differentiation of sister cells at dozens of lineage branches; and (iii) most distinct lineages that produce the same anatomical cell type converge to a homogenous transcriptomic state.

Intestinal microbiota: A potential target for enhancing the antitumor efficacy and reducing the toxicity of immune checkpoint inhibitors
Cancer Lett · 2021 · PMID:33845122
ABSTRACT

Accumulating evidence suggests that the intestinal microbiota is associated with the antitumor efficacy of immune checkpoint inhibitors (ICIs) and the occurrence of immune-related adverse events (irAEs) following ICI treatment. However, the mechanisms underlying these interactions remain unclear. Recent technological advances have allowed more extensive investigation into the interplay between the intestinal microbiota and the tumor immune microenvironment. Breakthroughs by two research groups revealed that Bifidobacterium enhanced the efficacy of ICIs via the stimulator of interferon genes (STING) and adenosine 2A receptor (A2AR) signaling pathways, highlighting the molecular mechanisms through which the intestinal microbiota modulates immunotherapy. In this review, we summarize recent findings related to the potential role and mechanisms of the gut microbiota in ICI therapy, available microbiota-targeting strategies, and ongoing clinical trials. Further we discuss the associated chal
