Estudio de células senescentes por citometría de imagen

, 2019
La senescencia celular, conocida como la detención irreversible de la división celular, puede ser inducida por agentes oxidantes y radiación ultravioleta entre otros. Las células senescentes se distinguen por una serie de rasgos morfológicos y moleculares, entre los que desataca el incremento de la actividad β-Galactosidasa lisosomal.

Astrocytic LMP2 Coordinates NF‐κB and TGF‐β1/Smad3 Signaling to Drive Neuroinflammation after Cerebral Ischemia/Reperfusion

Advanced Science, EarlyView.
ABSTRACT Astrocyte reactivity critically shapes neuroinflammatory outcomes after ischemic stroke, yet the upstream regulators governing astrocyte state transitions remain incompletely defined. Here, we identify the immunoproteasome subunit low molecular weight protein 2 (LMP2) as an important modulator of astrocyte functional remodeling following ...

Engineered Exosomal miR‐146a‐5p Reprograms BMSC Fate and Restores Mitochondrial Homeostasis in Glucocorticoid‐Induced Osteonecrosis of Femoral Head

Advanced Science, EarlyView.
Exosomal miR‐146a‐5p is identified as a pivotal regulator in steroid‐induced osteonecrosis. Its reduction activates NF‐κB signaling, compromises mitophagy, and disrupts mitochondrial bioenergetics, resulting in autophagic disequilibrium. Engineered exosomes delivering miR‐146a‐5p reinstate mitochondrial function, augment oxidative phosphorylation and ...

Traslación nutrimental e incremento medio anual en teca (Tectona grandis L.f.), en Tabasco, México

Colombia Forestal
La traslación nutrimental es la cantidad de nutrientes que son movilizados desde las hojas senescentes a otros tejidos de los árboles. El objetivo de este estudio fue estimar la traslación nutrimental y el incremento medio anual (IMA) en diámetro, altura

p300 Degradation by the p53‐SIAH1 Axis Relieves TBK1 Acetylation to Enhance Innate Antiviral Immunity

Advanced Science, EarlyView.
This study identifies p300 as the acetyltransferase that acetylates TBK1 and inhibits its phosphorylation. Activation of the p53‐SIAH1 axis by immune response downregulates p300 expression to sustain innate antiviral immunity. Conditional p300 knockout in alveolar epithelial cells in vivo promotes antiviral responses and suppresses virus replication ...
