Adenosine News and Research

RSS

Adenosine is a nucleoside composed of a molecule of adenine attached to a ribose sugar molecule (ribofuranose) moiety via a ß-N9-glycosidic bond.

Researchers combine two nanomachines to build lifelike DNA networks

Drawing inspiration from the dynamic architecture of living systems, researchers from Institute of Science Tokyo and Kyoto University have harnessed two chemically fueled biomolecular nanomachines, DNA polymerase and kinesin, to synthesize and actively assemble complex, hierarchical DNA networks.

Mitochondrial rewiring may explain why orthoflaviviruses harm humans but persist in mosquitoes

Orthoflaviviruses reshape mitochondrial structure, metabolism, redox signaling, and quality control differently across human and mosquito models, helping explain their contrasting infection outcomes. The review highlights mitochondrial pathways that may support acute cellular damage in vertebrates but persistent, non-lethal infection in mosquitoes, pointing to potential antiviral targets.

The coffee advice given to atrial fibrillation patients may deserve a rethink

The DECAF randomized trial found that adults with persistent atrial fibrillation or atrial flutter assigned to drink at least one cup of caffeinated coffee daily had a 39% lower hazard of recurrent clinically detected AF or flutter than those assigned to avoid coffee and caffeine. The findings challenge longstanding advice to routinely restrict caffeinated coffee in people with AF, while further research is needed to determine whether coffee itself provides a protective effect.

New review explores purinergic signaling pathways in osteoarthritis progression

A growing understanding of purinergic signaling is reshaping how scientists view osteoarthritis (OA), revealing an intricate communication network that influences joint inflammation, cartilage degeneration, bone remodeling, and chronic pain.

Perilla oil may curb platelet reactivity and inflammatory signaling in smokers

An eight-week randomized trial found that daily perilla oil increased plasma and red-cell ALA, plasma EPA, and platelet closure time in healthy smokers. Perilla oil also reduced TNF-α and TBX21 gene expression, but it did not improve broader coagulation, lipid, endothelial, or postprandial markers.

New mechanism linked to septic heart injury protection uncovered

Sepsis triggers widespread inflammation, circulatory failure and metabolic stress, and cardiac dysfunction is a common complication associated with sharply poorer outcomes.

Some caffeinated drinks are linked to poorer memory

A study on caffeine's impact reveals product-specific effects on anxiety, memory, and stress among university students, highlighting mental health implications.

A common dietary nutrient feeds a gut pathway linked to atrial fibrillation

Researchers linked higher plasma TMAO to prevalent atrial fibrillation in 5,090 people and found that TMAO or choline supplementation accelerated AF onset, progression, atrial remodeling, and electrical dysfunction in mice. Inhibiting gut microbial TMA production lowered circulating TMAO and delayed AF in mice, identifying a potential therapeutic pathway that now requires human testing.

MEK inhibition could limit T cell exhaustion and give a boost to immunotherapy

A major pillar of cancer immunotherapy involves stimulating T cells, the specialized killers of the immune system, to attack tumors.

Spermidine boosts key cellular processes linked to aging in early research

This review finds that spermidine supports autophagy, mitochondrial function, and healthspan in experimental models, while observational studies link higher dietary intake to lower mortality. However, human trials have produced limited and mixed results, leaving its clinical role in healthy aging unresolved.

Moderate coffee intake may support heart health, AHA says

The American Heart Association finds that habitual coffee consumption is associated with lower risks of several cardiovascular outcomes, although most evidence comes from observational studies. Moderate intake is generally safe for most adults, while energy drinks and individual caffeine sensitivity may increase cardiovascular concerns.

New genetic reference map accelerates human stem cell research

A team led by bioengineers at the University of California San Diego has developed a genome-scale reference map that details how individual genes control the functions and identities of human stem cells.

New EV-SELEX strategy accelerates drug discovery for wide range of GPCRs

G protein-coupled receptors (GPCRs) are the most abundantly expressed proteins in the human body, which regulate diverse physiological processes ranging from pain perception to hormone signaling.

Review assesses the efficacy of creatine as an add-on therapy for depression

Walk into any gym supplement aisle and creatine is there, sold by the tub to people chasing bigger muscles. It is one of the most studied compounds in sports science.

Review outlines key strategies to overcome antibody drug conjugate resistance

The first Antibody-drug conjugate (ADC) was approved overa quarter-century ago, and today more than 20 have reached the clinic.

Microbes trigger cell death to boost cancer immunotherapy effectiveness

Traditional cancer treatments like chemotherapy and radiotherapy can induce immunogenic cell death (ICD), but their efficacy is often limited by drug resistance, severe off-target toxicity, and immune-related adverse events.

Aging immune cells may explain why autoimmunity rises later in life

A new Review reveals how aging can push the immune system into a paradoxical state, weaker against threats yet more prone to attacking the body’s own tissues.

Gut bacteria may help explain why fatigue appears before illness

A small study of healthy Japanese adults found that fatigue was associated with distinct gut microbiome, microbial gene, and fecal metabolite patterns. The findings suggest fatigue may track with altered microbial energy metabolism and oxidative stress-related functional potential, but larger longitudinal studies are needed to test causality and clinical value.
