Rejuvenation medicine:
The next frontier in healthcare
Rejuvenation medicine targets the age-related deterioration of the human body. As an untapped market opportunity, rejuvenation medicine has the potential to curb the huge healthcare costs currently associated with diseases of aging while promising a longer healthspan.
Multiple types of molecular and cellular damage accumulate throughout life.

Loss of proteostasis
Proteins are essential for all cellular processes, but the mechanisms that maintain protein are inadequate in aged cells.

Epigenetic changes
Aging is associated with distinct modifications in the way DNA is stored, read and expressed, without altering the gene sequence.

Genetic instability
Failure of DNA repair mechanisms leads to loss of information and mutations of the genetic code in aged cells.

Telomere attrition
Telomeres, the protective caps of chromosomes, shorten each time a cell divides. When telomeres are too short, cells become unable to replicate.

Dysregulated nutrient sensing
Handling excess nutrients is a big challenge for cells. The mechanisms that control nutrient availability and utilization fail with age.

Mitochondrial dysfunction
Mitochondria consume oxygen and produce almost all the energy cells use. Mitochondria become leaky and inefficient with aging.

Cellular senescence
Senescent cells accumulate in aged tissues. As a result, they stop functioning properly, causing inflammation that damages the organism.

Stem cell exhaustion
In aged organisms, the pool of stem cells decreases, causing a declination of the regeneration capacity of individual stem cells.

Altered intercellular communication
Aged cells fail to coordinate their metabolism and function leading to unnecessary chronic inflammation.

Scientific Director and Partner
José is a physician and molecular biologist with several years’ experience in aging research. He studied medicine at Universidad Panamericana and pursued Ph.D. studies at McGill University. Jose has performed basic research on several processes involved in aging, including stem cell differentiation, protein quality control, and cellular energy production.

Reason
Advisor
Reason is co-founder and CEO of Repair Biotechnologies. He has been an active angel investor in the longevity industry since its earliest days, with investments including Oisin Biotechnologies and Leucadia Therapeutics. He is a long-standing and well-connected patient advocate for aging research, involved in numerous fundraising and outreach initiatives conducted by organizations such as the Methuselah Foundation and SENS Research Foundation since the early 2000s.

Carmela Abraham, PhD
Advisor
Carmela R. Abraham, Ph.D., has devoted her entire career to the study of aging and Alzheimer’s disease (AD). She obtained her B.Sc. in Biology at Tel Aviv University and a Ph.D. in Neuroscience at Harvard University.
