Senolytic therapies suppress long COVID in human organoids, mouse models

Nov. 17, 2023
By Tamra Sami
Researchers from the University of Queensland discovered that senolytic therapies can suppress long-COVID neuropathology and long-term disorders caused by viral infections by reducing senescent cells, thereby reducing inflammation. Published Nov. 13, 2023, in Nature, the study examined the use of human pluripotent stem cells to generate small mini human brain organoids to screen for antiaging interventions called senolytics that selectively eliminate senescent cells that accumulate with age, lead author Julio Aguado told BioWorld.

Mitophagy inducer prolongs life and prevents neurodegeneration

Nov. 15, 2023
By Mar de Miguel
A new derivative of coumarin, a natural plant product abundant in cinnamon, could hold the key to healthy aging. Researchers at the Buck Institute have shown that it extended life span and prevented neurodegenerative disease in worms and mice. The drug, a TFEB gene inducer called MIC, promoted mitochondria recycling (mitophagy) but also interacted with lysosomes, which could have multiple applications. The scientists published the results of this aging and mitophagy study on Nov. 13, 2023, in Nature Aging.

Longevity AI-biotech Gero raises $6M in series A round for aging research

Oct. 31, 2023
By Marian (YoonJee) Chu
“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.

From membranes to metabolites, looking at lipids

Sep. 14, 2023
By Anette Breindl
Lipids are “very diverse, but also vastly understudied,” Anne Brunet told the audience at the recent meeting on Aging Research and Drug Discovery. Advances in the ability to predict protein structures have fueled a much better understanding of the human proteome and its estimated 20,000 members. The lipidome is much larger, numbering maybe 100,000 total. And what those lipids do remains much more fuzzy. “Very little is known about their function, and especially their function during aging,” Brunet said. Slowly, however, technological advances are enabling researchers to understand the roles of lipids as well.

Mitochondrial modulator rejuvenates blood stem cells

Sep. 4, 2023
By Nuala Moran
Researchers have demonstrated that inhibiting mitophagy in ‘old’ hematopoietic stem cells (HSCs) completely restored their blood reconstitution capabilities, raising the prospect of addressing the age-related weakening of the immune system that stems from HSCs deteriorating over time.

Neuronal, blood vessel miscommunication affects aging heart: study

Aug. 31, 2023
By Anette Breindl
Throughout the body, the vasculature and the nervous system are fellow travelers. Renaissance physician and anatomist Andreas Vesalius described their proximity on the macroanatomical level in the 16th century, and modern microscopic techniques have shown that it extends into the micrometer range – where there is a blood vessel, there is often a nerve nearby, and vice versa.

Biomarker brainteaser: Aging? Or just changing?

Aug. 30, 2023
By Anette Breindl
“Change is the only constant” is an ageless truth. In the search for age-related biomarkers, it is also a prosaic confounding factor.

Age-related biomarkers will be critical for the development of antiaging therapeutics. “Nobody is planning to do a life span study in humans,” Eric Verdin told the audience at the 10th Conference on Aging Research and Drug Development in Copenhagen on Monday. “Hence the need for … surrogate markers.”
