Longevity Roadmap

In this episode, we are joined by Dr. Judith Frydman to explore proteostasis: the tightly regulated systems that ensure proteins are correctly folded, maintained, and cleared before they become toxic. As these systems degrade with age, misfolded proteins accumulate, cellular signaling falters, and vulnerability to neurodegeneration increases. The discussion centers on why protein folding begins during translation, how molecular chaperones like TRIC preserve cellular integrity, and why aging creates a self-reinforcing cycle of proteostatic failure. We also examine upstream mechanisms—and what restoring proteostasis could mean for future longevity interventions, healthspan preservation, and disease prevention. Watch the full episode to understand why protein folding may be one of the most underappreciated levers in aging biology.

Over the past year, we covered a wide range of ground—from clinicians working directly with patients to top scientists studying the underlying biology of aging. This episode is a chance to look back at some of the more interesting conversations we had on Longevity Roadmap in 2025. Looking ahead, there's no sign that the pace is slowing. In longevity, it often feels like every year brings another set of breakthroughs, and 2026 is shaping up to be a big one. One of the most important trends to watch is the increasing role of artificial intelligence in medicine, particularly in pharmaceuticals. AI-driven, network-based drug repurposing efforts are starting to identify compounds that may influence aging biology and move more efficiently toward clinically relevant interventions. By the end of 2026, it's reasonable to expect early readouts or expanded trials that begin to meaningfully target the hallmarks of aging. Before wrapping up this year, I just want to say thanks to everyone who's been listening this year. Your interest, your feedback, and your willingness to think critically about this space are what make the show worth doing.

Aging begins when cellular quality-control systems lose their precision. In this episode, Professor Ana Maria Cuervo outlines how chaperone-mediated autophagy (CMA)—a selective lysosomal degradation pathway essential for proteostasis—progressively declines with age, triggering downstream failures across neuronal and metabolic tissues. Reduced LAMP2A availability, impaired lysosomal docking, and disrupted protein triage lead to toxic proteotoxic burden, mitochondrial dysfunction, and metabolic inflexibility. Emerging evidence shows that preserving CMA activity can improve healthspan, attenuate neurodegenerative pathology, and restore metabolic homeostasis.
