Brief Summary
Senescent cells shed large adhesion-dependent fragments, termed senescent-cell adhesion fragments (SCAFs), which facilitate the disposal of damaged mitochondria and promote cell survival. SCAFs subsequently rupture, releasing DAMPs and amyloid-like intracellular material. This process promotes wound-healing and cancer-associated programs.
Interview to the corresponding author Dr. Willam "Bill" M. Keyes (IGBMC)
What is the potential impact of this work?
This work identifies fragmentation as a previously unrecognized feature of cellular senescence that
supports cell survival while releasing potentially harmful intracellular material. These findings reveal a
new mechanism linking senescence to tissue dysfunction, with potential implications for aging, cancer and neurodegeneration.
What question does this paper open for the future?
Too many - are SCAFs present in tissues? Can we inhibit them as a seno-therapeutic strategy? what is
the link with amyloid deposition?
What does ICSA represent to you, and how does this paper connect with the ICSA community?
The ICSA is a critical organization that is needed to bring together all of the teams working on the diverse aspects of senescence, while helping give visibility to a still contentious topic. We feel this work has the potential to link with many aspects of senescence biology being studied by numerous other senescence teams.
