Cellular Senescence and Frailty in Transplantation

Area of Science:

• Transplantation immunology
• Gerontology
• Cellular biology

Background:

• Solid-organ transplant recipients experience accelerated aging due to factors including cellular senescence.
• Accumulated senescent cells secrete inflammatory and profibrotic factors, leading to tissue damage and frailty.
• Cellular senescence is increasingly recognized for its role in transplant-specific issues like allograft rejection and infections.

Purpose of the Study:

• To review the literature on cellular senescence and frailty in solid-organ transplantation.
• To highlight senotherapeutics as a potential treatment strategy for cellular senescence in transplant patients.

Main Methods:

• Literature review and synthesis of existing research on cellular senescence and frailty in solid-organ transplantation.
• Analysis of emerging senotherapeutic approaches.

Main Results:

• Cellular senescence is a significant contributor to aging, frailty, and adverse outcomes in solid-organ transplant recipients.
• Emerging senotherapeutic strategies, including senolytics and senomorphics, show potential for mitigating cellular senescence and frailty.
• These interventions may improve allograft immunogenicity, reduce infection susceptibility, and enhance overall patient and graft survival.

Conclusions:

• Cellular senescence and frailty negatively impact outcomes in solid-organ transplantation.
• Further research into the role of cellular senescence in transplantation is crucial for developing effective senotherapeutic approaches.
• Targeting cellular senescence holds promise for improving graft and patient outcomes in solid-organ transplantation.
