In Aging Cell, researchers have described how increasing fibroblast growth factor 13 (FGF13) in astrocytes reduces aging throughout the bodies of mice. A factor from a well-known family FGFs are signaling molecules that share structural and functional commonalities and play crucial roles in biology, including neural function [1]. Some of these molecules are secreted, and...

A team of researchers has written a paper with a surprising finding: that many of the benefits of caloric restriction and increased NAD+ may be due to their effects on the cilia of hypothalamic neurons. Neuronal cilia have a relationship to overall health Nicotinamide Adenine Dinucleotide (NAD): Benefits and ResearchNicotinamide adenine dinucleotide (NAD) is a...

A new study links an age-related decline in cellular maintenance to impaired immune clearance. Activating the pathway reduced signs of senescence in aged mice [1]. Senescence and autophagy Cellular senescence, which occurs when cells stop dividing and start emitting largely pro-inflammatory stress signals, the senescence-associated secretory phenotype (SASP), is a double-edged sword. On the one...

Autophagy, which increases in younger mice under toxic stress, does not increase in older mice and leaves them susceptible to acute kidney injury (AKI). Increasing autophagic flux by targeting a key molecule, transcription factor EB (TFEB), alleviates some of this damage. An acute disease with lasting effects AKI is a rapidly developing condition that causes...

Researchers have described a method of using exosomes derived from mesenchymal stem cells (MSCs) to fight harmful metabolic changes in the liver. Another look at exosomes This is far from the first attempt at using MSC-derived exosomes, particularly exosomes derived from MSCs originally taken from human umbilical cord tissue (HucMDEs derived from HucMSCs), to treat...

Researchers have explained how a protein found in both yeast and humans facilitates the destruction of the core protein responsible for Parkinson's disease. An aggregate that impairs clearance Loss of ProteostasisThe loss of proteostasis is the failure of the protein-building machinery of the cell and the accumulation of misfolded proteins, which is one of the...
