Targeting ATF6α Attenuates UVB‐Induced Senescence and Improves Skin Homeostasis by Regulating IL8 Expression

open access: yesAging Cell, EarlyView.
UVB exposure can trigger senescence in dermal fibroblasts. We show that silencing ATF6α disrupts the establishment of the UVB‐induced senescent phenotype by preventing the onset of several senescent biomarkers and altering the composition of the SASP, consequently affecting its impact on the skin microenvironment.

Identification of Senomorphic miRNAs in Embryonic Progenitor and Adult Stem Cell‐Derived Extracellular Vesicles

open access: yesAging Cell, EarlyView.
A senomorphic miRNA cocktail (E5), consisting of miR‐181a‐5p, miR‐92a‐3p, miR‐21‐5p, and miR‐186‐5p, was identified from a pool of miRNAs enriched in extracellular vesicles (EVs) derived from multiple functional human stem cell types. E5 reduces senescence and SASP markers both in cell culture and in aged mice.

Immunosenescence Profile Is Associated With Increased Susceptibility to Severe COVID‐19

open access: yesAging Cell, EarlyView.
(A) A previous immunosenescence profile in individuals infected with SARS‐CoV2 creates a permissive environment for progression to severe COVID‐19: higher inflammaging, accumulation of exhausted/senescent T cells, an oligoclonal B‐cell repertoire, and accelerated epigenetic age.

Nuclear Import Defects Drive Cell Cycle Dysregulation in Neurodegeneration

open access: yesAging Cell, EarlyView.
Overview of Dysregulated Cell Cycle Mechanisms in Neuronal Cells. A nuclear import block drives cell cycle re‐entry from G0, culminating in cell cycle arrest at G1/S. This cell cycle arrest is associated with activation of CKIs from the INK locus (p15, p16, p18, p19) and Cip/Kip (p21, p27) which act on specific CDK/Cyclin complexes.

hTERT Increases TRF2 to Induce Telomere Compaction and Extend Cell Replicative Lifespan

open access: yesAging Cell, EarlyView.
In contrast to the dogma that a subset of short telomeres initiates senescence, hTERT variants unable to maintain telomere length block senescence by stabilizing TRF2 via inhibiting upstream E3 ubiquitin ligases. This noncanonical hTERT function also compacts telomeres and blocks senescence‐associated DNA damage signaling. Cancer cells expressing hTERT
