Fusion and Fission: Why Mitochondria Have to Change Shape

Mitochondria don't just produce energy. They constantly merge, divide, and reorganize. Discover why this process matters for mitochondrial function, quality control, and healthy aging.

When Worn Mitochondria Keep the Immune System on Alert

Damaged mitochondria can trigger immune alarms even without an infection. Why do some aging cells keep those signals active, and what does mitochondrial maintenance have to do with it?

Autophagy Is Not the Same as Mitophagy

Autophagy helps cells recycle unwanted material, while mitophagy specifically targets damaged or worn mitochondria. But removing what no longer works is only half the story: how do cells repair, rebuild, and maintain the mitochondria they need to stay healthy?

Why Aging Muscle Can Still Make Energy but Lose Capacity

Aging muscle does not simply lose its ability to make energy. Research suggests mitochondrial energy production can remain surprisingly resilient while other functions, including calcium handling and cellular maintenance, become less robust.

Why Damaged Mitochondrial DNA Changes the Aging Conversation

As we age, we tend to lose mitochondrial capacity. But having fewer mitochondria does not tell the full story. The quality of the mitochondria that remain, including the condition of their DNA, also plays an important role in how well cells continue to produce and manage energy.

NAD and Mitochondrial Capacity: Why More NAD Is Not Enough

Raising NAD+ may support cellular energy metabolism, but does more NAD+ actually mean better mitochondria? The answer depends on what happens beyond NAD+.

ROS Are Not the Enemy: How Cells Turn Stress Into Adaptation

Reactive oxygen species are usually portrayed as cellular enemies. In controlled amounts, however, they help cells respond to exercise, tissue injury, and mitochondrial stress. The real issue is when a useful signal becomes chronic noise.

Cardiolipin: The Mitochondrial Fat Almost Nobody Talks About

Cardiolipin is a specialized phospholipid found mainly in the inner mitochondrial membrane. Its unusual four-tailed structure helps support mitochondrial cristae and the proteins involved in ATP production. Here is why this little-known membrane lipid matters for mitochondrial organization, energy production, and renewal.

Cómo se influyen mutuamente el microbioma y las mitocondrias

La microbiota intestinal no solo favorece la digestión. Los metabolitos microbianos pueden influir en el uso de energía, la señalización y el control de calidad de las mitocondrias, mientras que estas, a su vez, contribuyen a configurar el entorno intestinal.

Las mitocondrias, el estrés oxidativo y la falta de uniformidad en el tono de la piel

La irregularidad del tono de la piel no es solo un problema superficial. En este artículo se explica cómo se relacionan entre sí el estrés oxidativo, las mitocondrias, la exposición a los rayos UV y el cuidado diario de la piel.

Mitochondria, Collagen, and Skin Structure: The Biology Beneath Firmness and Elasticity

Skin firmness is not only about collagen. This article explains how mitochondria, fibroblasts, oxidative stress, and hydration shape the biology beneath elasticity.

Heat, Cold, and Mitochondrial Hormesis: How Temperature Stress May Shape Cellular Resilience

Heat and cold can act as controlled stress signals for mitochondria. Learn how mitochondrial hormesis, thermogenesis, heat shock proteins, and recovery shape cellular resilience.
