Lipofuscin accumulation in aging and neurodegeneration: a potential “timebomb” overlooked in Alzheimer’s disease
Lipofuscin, a marker of aging, is the accumulation of autofluorescent granules within microglia and postmitotic cells such as neurons. Lipofuscin has traditionally been regarded as an inert byproduct of cellular degradation. However, recent findings suggest that lipofuscin may play a role in modulating age-related neurodegenerative processes, and several questions remain unanswered. For instance, why do lipofuscin granules accumulate preferentially in aged neurons and microglia? What happens to these pigments upon neuronal demise? Particularly in neurodegenerative diseases like Alzheimer’s disease (AD), why does amyloid β (Aβ) deposition usually begin in late adulthood or during aging? Why do lipofuscin and amyloid plaques appear preferentially in grey matter and rarely in white matter? In this review, we argue that lipofuscin should be revisited not as a simple biomarker of aging, but as a potential modulator of neurodegenerative diseases. We synthesize emerging evidence linking lipofuscin to lysosomal dysfunction, oxidative stress, lipid peroxidation and disease onset—mechanisms critically implicated in neurodegeneration. We also explore the potential interactions of lipofuscin with Aβ and their spatial location, and summarize evidence showing that lipofuscin may influence disease progression via feedback loops affecting cellular clearance and inflammation. Finally, we propose future research directions toward better understanding of the mechanisms of lipofuscin accumulation and improved lysosomal waste clearance in aging.

Heart-brain connection: International study reveals role of vagus nerve in keeping the heart young
The secret to a healthier and “younger” heart lies in the vagus nerve. A recent study coordinated by the Sant’Anna School of Advanced Studies in Pisa and published in Science Translational Medicine has shown that preserving bilateral cardiac vagal innervation is an anti-aging factor. In particular, the right cardiac vagus nerve emerges as a true guardian of cardiomyocyte health, helping to preserve the longevity of the heart independently of heart rate.
The study is characterized by a strongly multidisciplinary approach, integrating experimental medicine and bioengineering applied to cardiovascular research. Specifically, the research was led by the Translational Critical Care Unit (TrancriLab) of the Interdisciplinary Research Center Health Science, under the responsibility of Professor Vincenzo Lionetti, and by the laboratory of the Biorobotics Institute led by Professor Silvestro Micera, which contributed to the development of the bioabsorbable nerve conduit used to facilitate vagal regeneration.
The study involved a broad network of Italian and international institutions of excellence, including the Scuola Normale Superiore, the University of Pisa, the Fondazione Toscana G. Monasterio, the Institute of Clinical Physiology of the CNR, the University of Udine, GVM Care & Research, Al-Farabi Kazakh National University, the Leibniz Institute on Ageing in Jena and the École Polytechnique Fédérale de Lausanne.
Longevity in 2025: The Breakthroughs That Actually Mattered
This year quietly rewired how researchers think about aging, what truly predicts long-term health, and which biohacking ideas deserve serious attention versus skepticism. From brain aging to muscle strength, from AI-driven drug discovery to cooling hype around supplements, 2025 redrew the map of healthspan science.
Here’s the clear-eyed recap of what actually mattered.
Protein MCL1 links cancer cell survival and energy metabolism
A study by the Mildred Scheel Early Career Center group led by Dr. Mohamed Elgendy at the TUD Faculty of Medicine provides fundamental insights into cancer biology. Published in Nature Communications, the study shows for the first time that the protein MCL1 not only inhibits programmed cell death, but also plays a central role in tumor metabolism.
The researchers have succeeded in tracing two classic hallmarks of cancer—the evasion of apoptosis (a form of programmed cell death) and the dysregulation of energy metabolism—back to a common molecular mechanism.
The study focuses on the protein MCL1, which is strongly overexpressed in many tumor types and has previously been considered primarily an anti-apoptotic factor of the Bcl-2 protein family.
How an antiviral defense mechanism may lead to Alzheimer’s disease
One of the main proteins that contributes to Alzheimer’s disease is called phospho-tau (p-tau). When p-tau gets too many phosphate groups attached to it (a process called hyperphosphorylation), it starts to stick together and form clumps called “tangles” inside of brain nerve cells.
A new study by Mass General Brigham investigators shows that tau hyperphosphorylation may be a consequence of an antiviral response that protects the brain from infection. Results are published in Nature Neuroscience.
“As a geneticist, I always wondered why humans had evolved gene mutations predisposing to Alzheimer’s disease,” said senior author Rudolph Tanzi, Ph.D., Director of the McCance Center for Brain Health and Genetics and Aging Research Unit in the Mass General Brigham Department of Neurology.
