Mitochondria are essential for cell survival, repair, and adaptation. Not only do they generate most of the energy needed during a cell's life, but they also regulate cell death, calcium balance, and ...

Cells throughout the human body become less efficient with age, and a newly published study points to a specific lipid, ...

A first-in-human clinical trial of an immune rejuvenation therapy designed to restore the function of worn-out T cells is ...

Mesenchymal drift may help explain how cells lose stable identity and acquire pro-fibrotic, inflammatory mesenchymal traits during aging. The review proposes MD as a unifying framework that links ...

Read on to understand how sickle-shaped red blood cells block blood vessels, trigger pain crises and may lead to organ damage ...

Cilia are ubiquitous on cells, playing a variety of roles, Dr. Nicastro explained. While non-motile cilia serve as sensors for chemical and mechanical signals, motile cilia rhythmically beat to propel ...

People need to sleep, and sleep deprivation can cause many changes in the brain. But we have a poor understanding of why sleep is so crucial. New research has examined a fruit fly model to assess how ...

Scientists at City of Hope have uncovered a gene called SMOC1 that plays a surprising role in the development of type 2 diabetes (T2D) by converting pancreatic cells that normally produce insulin into ...

Scientists have discovered that cells can sense far beyond the surfaces they touch. While individual cancer cells can probe about 10 microns ahead by tugging on surrounding collagen fibers, clusters ...

Researchers have a new hypothesis for how brain cells called astrocytes might contribute to memory storage in the brain. Their model, known as dense associative memory, would help explain the brain's ...

The regulatory division of the immune system is vital for its overall function. Immune T cells originate in the bone marrow and then travel to the thymus—a kind of biological police academy. 2 Here, ...
