Traditional antibody therapies, while promising in some studies, are too large to enter cells in order to affect the aggregates there.
Scientists Move the Boundaries of Post-Mortem Recovery: Researchers have been able to achieve substantial recovery of cellular and organismal activity in pigs that had been dead for a full hour. Advances in resuscitation have already moved the boundaries of life and death, making it possible to revive a person several minutes after the heart stops beating.
An In-Depth Review of Skin Aging Genes: In a new systematic review published in Scientific Reports, multiple genes driving skin aging were identified. The authors start by explaining the intrinsic (genetic and chronological) and extrinsic (environmental) factors that drive skin aging.
Hypertension Is Associated with Brain Drainage Changes: Researchers publishing in Aging have found that enlarged perivascular spaces in the brain are correlated with vascular disorders. These spaces, which are part of the brain’s glymphatic system, allow for the drainage of potentially dangerous metabolites such as beta amyloid.
Rapamycin-Loaded Microneedles Reverse Hair Loss in Mice: Scientists have successfully regrown hair in a mouse model of hair loss using custom-made plastic microneedles loaded with rapamycin and epigallocatechin gallate (EGCG), an active ingredient in green tea.

Combining Senolytic Pathways Has Synergistic Effects: A team of researchers have explained in Aging how multiple compounds that target the BCL-2 protein family are considerably more effective against senescent cells than each compound by itself.
New Synthetic Molecule Alleviates Alzheimer’s in Mice: Scientists have synthesized a molecule that alleviates Alzheimer’s in a mouse model by targeting inflammation. Two of the most prominent – and probably interconnected – symptoms of Alzheimer’s disease are the accumulation of amyloid beta (Aβ) and chronic neuroinflammation.
The Relationship Between Stroke and Inflammation: Publishing in Aging, a team of Chinese researchers has provided evidence showing a relationship between systemic inflammation and prognosis after a stroke. As the researchers point out, strokes are the leading cause of death in China.
Almost Half of Cancer Deaths Worldwide are Preventable: Researchers have shown that 44.4% of cancer deaths worldwide can be attributed to preventable risk factors, including behavioral and environmental ones. It is well known that many cancer cases occur due to behavioral and environmental and factors such as smoking and pollution, which makes them theoretically preventable.
Rapamycin and Metformin Show Synergy in Mice: Scientists have found that rapamycin and metformin work hand in hand in diabetes-prone mice, boosting each other’s effectiveness and blocking side effects. Both have been in use for various indications for decades and have decent safety profiles.
Plasma Dilution Appears to Rejuvenate Humans: Published in GeroScience, a groundbreaking study from the renowned Conboy lab has confirmed that plasma dilution leads to systemic rejuvenation against multiple proteomic aspects of aging in human beings. This paper takes the view that much of aging is driven by systemic molecular excess of signaling molecules, antibodies, and toxins.
Mitochondrial Drug Alleviates Atherosclerosis in Mice: Scientists have drastically improved various symptoms of atherosclerosis in mice by precisely targeting mitochondria with a plant-derived antioxidant. Atherosclerosis, the accumulation of plaques on arterial walls, is one of the deadliest age-related diseases.
Intravenous Stem Cells Alleviate Guinea Pig Osteoarthritis: Scientists have shown that intravenous delivery of mesenchymal stem cells, which has some advantages over the more conventional intra-articular injection, alleviates age-related osteoarthritis and decreases inflammation in guinea pigs. Osteoarthritis, a degenerative joint disease, is one of the most common causes of disability in old age.
Glycans as Biomarkers of Aging: In a new review published in Clinica Chimica Acta, researchers from the University of Zagreb discuss immunoglobulin G glycans, the changes that their composition undergoes with aging, and their potential as biomarkers of aging. One of the review’s co-authors is Prof. Gordan Lauc, who gave a presentation on them at EARD2022.
