Heart and veins
The latest research published in the Journal of Anatomy found that spermidine alters the morphology of mitochondria in aged mouse heart tissue [1]. Mitochondrial dysfunction in the aging heart Why we Age: Mitochondrial DysfunctionAs they age, the mitochondria in our cells lose their ability to provide cellular energy and release reactive oxygen species that harm...
Bladder
In an important proof-of-concept study, scientists have successfully employed a ferroptosis activator and an mTOR inhibitor against bladder cancer cells [1]. Ferroptosis – "the iron death" Ferroptosis is a distinct type of cell death that gets less attention and is less well understood than the more ubiquitous and familiar apoptosis. As its name suggests, ferroptosis...
Elderly eyes
In a new paper published in Aging, researchers have determined that directly improving autophagy through flubendazole (FLBZ) is potentially useful in treating dry age-related macular degeneration (AMD), a disease that causes vision loss. An accumulation of lipids Dry AMD shares a surprising commonality with atherosclerosis. As our macrophages attack the fatty (lipid) deposits in our...
Spermidine supplement may slow down aging.
Recently published research in Cell Reports provides a detailed account of dietary spermidine improving cognition and mitochondrial function in flies and mice, with some prospective human data to top it off. Spermidine and longevity Spermidine is known to decline with aging, and treatment with spermidine extends lifespan across various species. While it has a myriad...
Autophagy
Genes in the sirtuin family are conserved across a wide range of species and are involved in cellular metabolism, immune response, and aging. SIRT1 is known to decline during aging, but the mechanisms involved in this process were not known. Now, an international team has clarified how SIRT1 is regulated during cellular senescence [1]. Why...
Glia Alzheimer's
The macrophages resident in the brain and spinal cord appear to be a key element in the progression of Alzheimer's disease, according to the results of a new mouse study. Microglial mayhem As we age, our immune cells become increasingly dysfunctional; once-helpful cells can behave in harmful ways, promoting persistent inflammation, impairing tissue regeneration, and...
