Age-related diseases have been explained as due in part to the excessive generation and accumulation of waste products like the various insoluble protein aggregates observed in nondividing neurons of Alzheimer’s disease, Parkinson’s disease, amyotrophic lateral sclerosis and Huntington’s disease.

Pretzel Therapeutics Inc. has launched with a $72.5 million series A financing to pioneer novel therapies to modulate mitochondrial function to treat rare genetic diseases and common diseases of aging.

A brief pulse of rapamycin before the onset of aging extended lifespan by triggering lasting increases in autophagy. The authors called this phenomenon "rapamycin memory." Elevated autophagy was accompanied by increased levels of LManV and lysozyme in fruit flies, in intestinal enterocytes in female fly models, and its Man2B1 homologue in mice. In mice, a 3-month treatment in early adulthood had the same effect as chronic treatment, even 6 months after rapamycin was withdrawn. In the study published in the Aug. 29, 2022, issue of Nature Aging and led by researchers at the Max Planck Institute, scientists showed that the lifespan-increasing response to rapamycin treatment decreased with the age at which treatment is started.

Scientists have discovered an RNA-based mechanism that is involved in core hallmarks of a number of accelerated aging conditions and shown that therapies targeting this RNA reverses some of these hallmarks in human cells and extend life spans in mouse models.

Sequence analysis of 131 human brains has revealed the mutagenesis processes that take place throughout life, from development to senescence. In a new study published in the July 29, 2022, issue of Science, the authors described how high rates of brain somatic mutations (what they call hypermutability) correlated with age.

In this multipart special report, BioWorld explores the concept of extending lifespan, which is surprisingly well-validated by basic research. The team examined the latest science, the key biological drivers that can be targeted pharmacologically and the companies developing these potential “Fountain of Youth” candidate drugs.

There is no drug that will halt the inevitable process of getting older each year. But biopharmaceutical research can have a positive impact on preventing diseases that come with aging, thereby extending life for the masses, and more importantly, extending quality of life. Part one of BioWorld’s multipart series on extending the human lifespan looks at the increasing development and investment in the space.
