WASTE indexes published research — it does not host or republish full papers. Each entry is a metadata record compiled from open scholarly databases; the abstract is shown in full only where the paper is openly licensed, otherwise a short excerpt under fair use. Classifications are automated and approximate.

Dual Role of Microglial TREM2 in Neuronal Degeneration and Regeneration after Axotomy.

Pottorf TS, Lane EL, Haley-Johnson Z et al. · 2026 · The Journal of neuroscience : the official journal of the Society for Neuroscience

Spinal cord ventral horn microglia proliferate after nerve injuries and migrate toward cell bodies of injured motoneurons (MNs) enwrapping them. The significance of this microglia reaction has remained unclear. Moreover, some injured MNs…

Mechanisms for enhancement of μ-opioid receptor-mediated antinociception in the central nervous system through gallein-dependent modulation of downstream G protein βγ subunit signaling.

Ormes JA, Smrcka AV, Jutkiewicz EM · 2026 · Molecular pharmacology

The clinical utility of μ-opioid receptor (MOR) agonists is limited by side effects and tolerance. G protein βγ subunits (Gβγ) are critical mediators of MOR signaling that not only drive anticonception but also regulate phospholipase C and…

Relaxation of Guinea Pig Aorta Induced by 5-HT<sub>2B</sub> Receptor. Exploration of Potential Mechanisms.

Del-Ángel-Monroy S, Rodríguez-Márquez A, Orozco-Suárez S et al. · 2026 · Basic & clinical pharmacology & toxicology

Vascular relaxation induced by 5-HT 2B receptor is thought to be mediated by stimulation of endothelial nitric oxide synthase (eNOS), but this assumption still requires investigation. To investigate potential mechanisms, BW723C86 (5-HT 2B…

Synergism of TNF and IFNγ promotes cell death, but TNF drives innate immune-mediated colitis independent of IFNγ.

Torres-Huerta A, Ruley-Haase K, Boger-May A et al. · 2026 · Journal of immunology (Baltimore, Md. : 1950)

The cause of inflammatory bowel disease (IBD) is not known, but both innate and adaptive immunity contribute to IBD pathogenesis. To better understand the contributions of innate immunity to IBD, we have generated a mouse model of IBD that…

Impact of 14 days of head-down bed rest and an exercise countermeasure on skeletal muscle atrophy, proteome and circulatory cytokines in older adults.

Lagacé JC, St-Martin P, Avino M et al. · 2026 · Experimental physiology

Prolonged bed rest and immobilization have deleterious effects on skeletal muscle mass and function, especially in older adults. These can lead to reduced physical capacity and quality of life. Previous experiments in younger individuals…

Evaluation of Nicotinamide Riboside in Prevention of Small Nerve Fiber Axon Degeneration and Promotion of Nerve Regeneration.

Thomas S, Ben-Davies R, Cetinkaya-Fisgin A et al. · 2026 · Journal of the peripheral nervous system : JPNS

Background and aims Recent preclinical studies have shown that nicotinamide adenine dinucleotide (NAD + ) plays a critical role in molecular mechanisms of axon degeneration, and reductions in NAD + levels are associated with axonal…

Dasatinib and quercetin prevent alveolar bone loss in aged mice.

Battistelli LS, Moraes RM, Santos YC et al. · 2026 · Journal of periodontology

Background Recent findings have associated alveolar bone loss (ABL) with the presence of senescent cells. Aging and the accumulation of senescent cells are associated with a pro-inflammatory environment which may exacerbate tissue damage.…

Long‐term comparison shows protected and non‐protected forests differ in harvesting, but not in wildfires or drought‐driven dieback

Espelta JM, Viana‐Soto A, Molowny‐Horas R et al. · 2026 · Journal of Applied Ecology.

While disturbances are essential for biodiversity, their escalation driven by climate change may threaten forest ecosystems. Contrasting approaches to adapt forests to disturbances-intensifying management versus encouraging natural…
