Alzheimer’s disease (AD) is recognized worldwide for its debilitating symptoms of declining cognitive function and gradual memory loss. What remains less clear is exactly what causes the neurodegenerative disease, and how to treat it. “Alzheimer’s disease is characterized by two key pathologies – beta-amyloid plaques and tau neurofibrillary tangles.” Seung-Yong Yoon, CEO of Adel Inc., told BioWorld. “Adel is looking to develop a tau-targeting drug, considering tau has been more correlated with AD symptom progression, and the industry’s need for tau pipelines.”

“Aging is not only slow, but it is irreversible, and that is what most people have been suspecting,” Gero Pte Ltd.’s CEO Peter Fedichev recently told BioWorld. “[But] aging is not an inevitable part of human existence.” By setting limits to what science can do – and not do – for aging, the Palo Alto, Calif.- and Singapore-based generative artificial intelligence (AI) biotech Gero is trying to figure out and, at the same time help the industry, “see what is actionable, reversible and what may not be” to help people avoid “hitting their heads against the wall” when tackling aging and aging-related diseases.

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.
