mitochondria

Cellular oxygen consumption in the brain may shed new light on Alzheimer’s disease onset, progression, and treatment.

Tiny but mighty, the mitochondria continue to surprise scientists with new insights into their diverse roles within cells.

A team demonstrated that ultrasound waves improved motility in sperm.

Reactive oxygen species cause mutations to DNA bases that can lead to cancer, but the long-blamed mitochondria could have been wrongfully charged.

Scientists seek citizens’ help to survey placental mitochondria in complicated and healthy pregnancies.

Researchers reveal that cellular secretion removes defective mitochondria when lysosomes are dysfunctional.

Regulatory T cells in muscles surge after exercise, quelling inflammation, protecting mitochondria, and enhancing performance.

An endoplasmic reticulum associated protein holds mitochondria in place in dendrites. This spatial stabilization possibly provides a local energy source for synaptic plasticity. 

Dietary changes rapidly alter T cell metabolism, but the effects can be reversed.

Following decades of being called “the powerhouse of the cell,” researchers recently proposed a new description that reflects the multifaceted roles of mitochondria.

As scientists realize the multifaceted role of mitochondria, some feel that the “powerhouse of the cell” analogy is out of date.

Annie Curtis’s research team revealed how circadian rhythm-regulated mitochondrial metabolism drives dendritic cell antigen presentation activity.

Researchers discover that neurons trade protein aggregates for microglial-derived mitochondria through tunneling nanotubes. 

Altering the rate of respiration in mitochondria changes how fast neurons grow, making mouse neurons grow more like human ones and vice versa, a study finds.

The Duke University cell biologist uses live-cell microscopy to reveal how brain cells rid themselves of damaged mitochondria and what goes wrong in neurodegenerative disease.

The findings answer the longstanding question of where these cells hold the mRNA needed to cope with the transcriptional halt preceding meiosis.

Genetic material pilfered from mitochondria may seal cracks in our genetic code, a study suggests.

Despite recent advances in the study of eukaryogenesis, much remains unresolved about the origin and evolution of the most complex domain of life.

A lot happened in the hundreds of millions years separating the first and last eukaryotic common ancestors, but when and how most features arose remains a mystery.
