Senescent cell clearance could be one of the big treatments to at least slow down one of the underlying causes of aging.

Treating Osteoarthritis by Removing Senescent Cells – LEAF – 3-May-2017
Researchers used local clearance of senescent cells (in mice) to reduce the development of post-traumatic osteoarthritis and encourage tissue regeneration.
Senescent cells accumulated in the articular cartilage and synovium after they induced anterior cruciate ligament injury.
Selective elimination of these cells reduced the development of osteoarthritis post injury, reduced pain and encouraged cartilage development.
Researchers used a compound called UBX0101 a senolytic drug created by Unity Biotechnology.
Hallmark of Aging Reversed by Senescent Cell Removal – LEAF – 25-Mar-17
Study directly targets one of the mechanisms that senescent cells use to avoid apoptosis,
Focused on FOXO4 (Forkhead box protein O4) and its influence on p53 gene.
Senescent cells increase expression of FOXO4 to escape apoptosis.
New approach potentially has fewer side effects.
New protein discovered in aging and cancer – Medical Xpress – 7-Mar-2017
Study describes a new way that senescent cells communicate via the expression of integrin membrane proteins.
Findings could one day lead to new treatments for ageing and early cancer.
A drug against integrin beta 3, called ‘cilengitide’, already exists that averts inflammation.
Science-Backed Therapy Targeting Senescent Cells May Be Future Anti-Aging Serum – Medical Daily – 11-Jan-2017
Growing older results in a build-up of the body’s senescent cells and naturally accumulate with age.
Senior rodents given therapy that removed these cells lived 25 percent longer and were able to regrow hair, run faster, and had improved organ function.
A perfect anti-senescence therapy would also kick-start tissue rejuvenation by stimulating differentiation of nearby stem cells.
Anti-aging therapies targeting senescent cells: Facts and fiction – Cell – 29-Dec-2016
Peter de Keizer of the Erasmus University Medical Center discusses strategy of removing senescent cells.
Need to identify how senescence impairs tissue rejuvenation and design compounds that can both target senescence and stimulate rejuvenation in a safe manner.
Cell-penetrating peptides may provide promising therapeutics.
With anti-senescence therapies we are the furthest we have ever been on the path to healthspan extension and restoration of the loss of health experienced during aging.
A Look at Ascendance Biomedical, Packaging Medical Tourism for Longevity Therapies – Fight Aging! – 28-Dec-2016
It is focused on the twofold path of
(a) establishing patient-funded trials of potentially useful therapies in the longevity science space
(b) packaging participation in trials and later purchase of therapies via medical tourism
The point is not Ascendance Biomedical today, it is the potential Ascendance Biomedical of a few years from now.
Targeting Senescent Cells with Synthetic Biology – LEAF – 9-Dec-2016
CellAge is going to develop synthetic promoters which are specific to senescent cells, as promoters that are currently being used to track senescent cells are simply not good enough to be used in therapies.

This start-up believes it can slow the aging process – Washington Post – 28-Oct-2016
Unity Biotechnology’s technology jump starts senescent cells into dividing again.
Company has raised $116 million.
Human trials planned in the next 12-18 months will focus on eye diseases
Ned David: “we do expect people to live free of a variety of chronic diseases.”
Secret to old age health could lie in purging worn-out cells – New Scientist – 16-Sep-2015
Cells eventually stop dividing to replace damaged neighbours and to into senescence.
Senescent cells produce inflammatory chemicals that underlie many aging related diseases.
Drug tests in mice show marked single dose of drugs have long lasting rejuvenation effects.

Vitamin stops the aging process in organs – Kurzweil AI – 6-May-2016
EPFL researchers restore ability of mice organs to regenerate – also extending life.
Administering nicotinamide riboside (NR) to organs helped mitochondria to function properly and reduce senescence.
Reduced regenerative capacity of organs leads to many of the disorders typical of aging.
Nicotinamide riboside is similar to vitamin B3 and is a precursor of NAD+.
More research required as boosting the functioning of all cells could include pathological ones.
Clearing the Body’s Retired Cells Slows Aging and Extends Life – The Atlantic – 3-Feb-2016
Cells accumulate damage in their DNA.
Eventually become senescent – i.e. they stop dividing – and are characterized by protein p16.
Team developed a way of singling out and removing those cells – increased lifespan of mice by a quarter.
Possibly “one of the more important aging discoveries ever.”
Have made an old organism physiologically younger – treatment instead of prevention.
