Surprise! This eukaryote completely lacks mitochondria

Mitochondria are membrane-bound components within cells that are often described as the cells' powerhouses. They've long been considered as essential components for life in eukaryotes, the group including plants, fungi, animals, ...

Lysosome to mitochondria communication regulates longevity

As people get older, they often feel less energetic, mobile or active. This may be due in part to a decline in mitochondria, the tiny powerhouses inside of our cells, which provide energy and regulate metabolism. In fact, ...

Anti-aging molecule NAD+ gets a boost from blocking an enzyme

Nicotinamide adenine dinucleotide (NAD+) is a major player in nutrition today. Studies have shown that NAD+ concentrations decrease during aging and that recovering the body's levels of NAD+ can prolong both health span and ...

Protein quality control and mitochondria

Protein aggregates are toxic for mitochondrial function, and thus disrupt the supply of chemical energy to their host cells. An LMU team has characterized a protein complex that prevents the build-up of such deposits in the ...

Cells stressed out? Make mitochondria longer

Scientists at The Scripps Research Institute (TSRI) have discovered a new pathway in cells that promotes mitochondrial function during times of stress, a response that can guard against disease as we age.
