The results demonstrated that aging caused senescent immunecellsto accumulate andsubpopulationsto reorganize, with a decrease in the proportion of naïve Tcells, whilst an increase in ...
However, proof of functional differences between suchsubpopulationsis lacking. To identify functionally distinct senescentcellsubpopulations, we employed high-content image analysis to measuresenescencemarker expression in primary human endothelialcellsand fibroblasts.
Overexpression of Hoxd8 led tosenescence-associatedphenotypes, suggesting HOXD8 is a new regulator of MEFsenescence. Together, our single-cellsequencing on senescent MEFs largely expanded the knowledge of a basiccellmodel for aging research.
Cellularsenescence, a state of persistent growth arrest, is closelyassociatedwithaging and age-related diseases. Deciphering the heterogeneity within senescentcellpopulations and identifying therapeutic targets are paramount for mitigatingsenescence-associatedpathologies. In this study, proteins on the surface ofcellsrendered senescent by replicative exhaustion and by exposure to ...
Cellularsenescenceis a phenotypic state that contributes to the progression of age-related disease through secretion of pro-inflammatory factors known as thesenescence-associatedsecretory phenotype (SASP). Understanding the process by which healthycellsbecome senescent and develop SASP factors is critical for improving the identification of senescentcellsand, ultimately, understanding ...
SenePy characterizescell-type-specific in vivo cellularsenescenceand could lead to the identification of genes that serve as mediators of cellularsenescenceand disease progression.
Abstract As the global population continues to age, understanding the complex role of cellularsenescenceand its implications in healthy lifespans has gained increasing prominence. Cellularsenescenceis defined as the irreversible cessation ofcellproliferation, accompanied by the secretion of a range of pro-inflammatory factors, collectively termed thesenescence-associatedsecretory ...
