Short-term sustained hyperglycaemia fosters an archetypal senescence-associated secretory phenotype in endothelial cells and macrophages

Redox Biology, 2018
Diabetic status is characterized by chronic low-grade inflammation and an increased burden of senescent cells. Recently, the senescence-associated secretory phenotype (SASP) has been suggested as a possible source of inflammatory factors in obesity ...

The multifaceted role of the SASP in atherosclerosis: from mechanisms to therapeutic opportunities

Cell & Bioscience, 2022
Background The global population of older individuals is growing, and ageing is a key risk factor for atherosclerotic cardiovascular diseases. Abnormal accumulation of senescent cells can cause potentially deleterious effects on the organism with age. As

Axonal growth arrests after an increased accumulation of Schwann cells expressing senescence markers and stromal cells in acellular nerve allografts [PDF]

, 2016
Acellular nerve allografts (ANAs) and other nerve constructs do not reliably facilitate axonal regeneration across long defects (>3 cm). Causes for this deficiency are poorly understood.

Bioelectrical Interfaces Beyond Excitable Cells: Cancer, Aging, and Gene Expression Modulation

Advanced Materials Interfaces, EarlyView.
ABSTRACT The investigation of biological conductivity has evolved from its classical foundation based on ionic fluxes underpinning cardiac and neuronal excitability to a multifaceted regulator of cellular physiology. Traditional approaches for probing electrical events in living matter focused largely on action potentials recording.

SENOLYTICS AND SENOMORPHICS: A NEW CLASS OF DRUGS FOR ANTI-AGING THERAPY

Central Asian Journal of Medical Hypotheses and Ethics
Aging is a complex biological process characterized by the accumulation of senescent cells that adopt a senescence-associated secretory phenotype (SASP), releasing proinflammatory mediators that drive tissue dysfunction and the onset of age-related ...

Pre‐Encoded IFN‐I Sensitivity Exacerbates Memory T Cell Senescence in Solid Tumors

Advanced Science, EarlyView.
Type I interferon (IFN‐I) signaling promotes p21‐dependent cell cycle arrest in senescent tumor‐specific memory T cells, resulting in poor proliferative responses and solid tumor regression during cancer vaccination. Conversely, IFNα/β receptor blockade reinvigorates T cell proliferation to regress solid tumors and is more effective with increasing ...

The Evolving Role of CD8+CD28- Immunosenescent T Cells in Cancer Immunology [PDF]

, 2019
Functional, tumor-specific CD8+ cytotoxic T lymphocytes drive the adaptive immune response to cancer. Thus, induction of their activity is the ultimate aim of all immunotherapies.

Farnesyltransferase Deficiency in Cardiomyocytes Initiates Senescence and Contributes to Cardiac Fibrosis

Advanced Science, EarlyView.
Lipid overload suppresses SREBF2‐mediated FNTB expression, leading to defective Lamin A maturation and nuclear envelope instability. This nuclear catastrophe triggers a pro‐fibrotic senescence program in cardiomyocytes. Notably, restoring nuclear integrity via AAV9‐based gene therapy effectively attenuates cardiac remodeling, identifying the ...

“Comparison of in vitro models for the study of senescence of macrophages associated with a tumor

Медицинская иммунология
Tumor-associated macrophages (TAMs) are an important and most represented population of immune cells in the tumor microenvironment. To a great extent, TAMs can determine the direction of the antitumor immune response; they can either additionally ...

Senolytic Treatment With Fisetin Reverses Age‐Related Endothelial Dysfunction Partially Mediated by SASP Factor CXCL12 [PDF]

Aging Cell
Single‐cell transcriptomics identifies that oral, intermittent fisetin supplementation improves endothelial function by targeting senescent endothelial cell‐derived senescence‐associated secretory phenotype (SASP) factors and CXCL12 in old animals. The SASP and specifically CXCL12 were found to drive age‐related endothelial dysfunction by promoting ...
