Lipids are a broad group of naturally-occurring molecules which includes fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E and K), monoglycerides, diglycerides, phospholipids, and others. The main biological functions of lipids include energy storage, as structural components of cell membranes, and as important signaling molecules.
University of Queensland researchers have uncovered the critical role that saturated fats play in the brain's memory consolidation process.
Cell death is fundamental to life and, thus, healthy aging. In the realm of cellular biology, ferroptosis (a form of programmed cell death) has emerged not only as a focal point of research for its potential in eliminating cancer cells, but also its role in a plethora of other diseases, including neurodegenerative diseases such as Alzheimer's disease, eye diseases such as Retinitis pigmentosa and age-related macular degeneration, as well as ischemia, cardiovascular disease, liver disease, acute kidney injury and inflammation.
For more than a century, scientists have been aware of a certain organelle found in plant cells. That organelle's crucial function in aging, however, has only recently been uncovered by UC Riverside scientists.
By exploiting the technology used in Covid-19 vaccines, a team led by UCL, King's College London and Moderna scientists has created an effective therapy for a rare disease, in a study in mice, demonstrating the technology's potential therapeutic use in people.
Some bacterial membrane transporters work almost like freight elevators to transport substances through the cell membrane into the interior of the cell. The transporter itself spans the bacterial membrane.
Amino acids are the building blocks of life. We obtain them from the food we eat, and the body uses them to make proteins, which in turn are used for growth, development, and a multitude of other functions.
The maintenance of a balanced lipid homeostasis is critical for our health. While consumption of excessive amounts of fatty foods contributes to metabolic diseases such as obesity and atherosclerosis, fat is an indispensable component of our diet.
Non-alcoholic fatty liver disease (NAFLD), characterized by an excess accumulation of hepatic lipids, is highly prevalent and can progress to cirrhosis and liver cancer.
Some Covid-19 vaccines safely and effectively used lipid nanoparticles (LNPs) to deliver messenger RNA to cells.
Paleontologists are gaining insight into life from over a billion years ago by analyzing chemical remnants in ancient rocks and studying the genetics of present-day animals.
Cheryl Rosenfeld has dedicated three decades to investigating the transmission of biological information from mothers to babies during pregnancy.
Messenger bubbles produced by human cells can pick up bacterial products and deliver them to other cells, University of Connecticut researchers report in the Nov. 16 issue of Nature Cell Biology.
Recycling is just as essential in cells as in our more familiar macroscopic world. Cells continuously generate waste products and accumulate damaged components while performing regular functions.
Cyanobacteria are a key species in Earth's history, as they introduced atmospheric oxygen for the first time. The analysis of their evolution therefore provides important insights into the formation of modern aerobic ecosystems.
Can plant-derived nutrients alter gut bacteria to affect brain function? Scientists from the University of Leipzig Medical Center, the Max Planck Institute for Human Cognitive and Brain Sciences and the Helmholtz Centre for Environmental Research investigated this question in a study of overweight adults.
The effectiveness of any drug molecule depends on how well it interacts with the internal environment inside our body.
Going meatless is undoubtedly fashionable, as seen by Impossible Burger and “Meatless Mondays.”
Every system has a waste management system. The “peroxisomes” are cell organelles that dispose of toxic substances and lipids in the human body, among other things, and thereby avoid major diseases.
In living organisms, cells have a very high capacity to process and communicate information by moving molecules or ions through tiny channels that span the cell membrane. UC Santa Cruz Professor of Electrical and Computer Engineering Marco Rolandi's lab and collaborators at MIT have created a device that mimics this biological concept in order to detect disease.
The sequencing of the human genome promised a revolution in medicine, but scientists soon realized that a genetic blueprint alone does not show the body in action.
