Skeletal muscles are organized into long fibers, and when a fiber breaks the entire fiber is often lost. This made a supporter worry that senolytic therapies might break a muscle fiber and eliminate precious fibers in aging muscles. It appears that the injury at the heart of the questioner’s worry does not happen in practice.

When blood from a biologically aged animal is transfused into a young one, the young animal suffers “pro-aging” effects. By contrast, reducing the burden of “pro-aging” signaling factors in old blood is not enough to remove existing damage from a similar-aged mouse’s biologically aged tissues.
UNITY Biotechnology was the first senolytic startup out of the gate, and the failure of its Phase II trial in osteoarthritis was a crushing disappointment. A careful look back at the underlying science and three new scientific papers give us a good idea why and suggest ways to move forward.
One way senescent cells accumulate is when one senescent cell turns a neighboring cell senescent through SASP secretion. SRF scientists have discovered that these secondary senescent cells are resistant to the classic senolytic drugs. However, they have identified a new senolytic strategy that kills these senescent cells.
Week One of our 2022 End of Year Campaign features ApoptoSENS (Removing Dysfunctional Cells) – with a disease focus on Challenging Alzheimer’s. Also featuring videos from Life Noggin, AMA with Dr. Amit Sharma and Michael Rae.
A supporter asks if SENS rejuvenation biotechnologies will benefit patients with progerias — so-called “premature aging” diseases.
For our SENSible Question series, a supporter asks if there are any common lab tests available that could be used as a readout of a person’s burden of inflammatory signals from senescent cells. The answer is ‘no,’ unfortunately, but we review a number of hard-to-access or research-only tests that might be able to tell us something with a bit more work.
