Lipids News and Research

RSS

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.

Researchers identify novel risk genes linked to bipolar disorder

Bipolar disorder (BD), characterized by mood swings between positive manic/hypomanic and negative/depressive states, is a common psychiatric disorder with a lifetime prevalence of ~1%.

New study shows outcomes after obesity surgery in teenagers

Obesity surgery has proven to be just as effective for teenagers as for adults. Five years on, those who underwent the procedure as teenagers weighed, on average, 28 percent less than prior to the surgery.

Characterizing the Brain - Cell by Cell

My group develops approaches to study cell-to-cell signaling in the brain – how the cells of the brain talk to each other. The brain is heterogeneous, probably more so than any other organ in our body, and many of its functions depend on the unique characteristics of these cells.

Exeter scientists discover how two cell organelles interact at molecular level

Scientists have made a breakthrough in understanding how different compartments (or organelles) of human cells interact.

Lipid content changes as cells age, new study reveals

As cells age and stop dividing, their fat content changes, along with the way they produce and break down fat and other molecules classified as lipids, according to a new University at Buffalo study.

Study shows structural impact of membrane lipids on medically relevant serotonin transporters

Neurotransmitter transporters are some of the most popular transport proteins in research as they play a major role in the processing of signals in the brain. A joint study by TU Wien and the Medical University of Vienna has now successfully demonstrated for the first time the structural impact of membrane lipids on medically relevant serotonin transporters.

Research finding provides new target for regulating cell division

Modern genome sequencing methods used to measure the efficiency of synthesis of individual protein during cell division has found that the enzymes that make lipids and membranes were synthesized at much greater efficiency when a cell is ready to split.

UIC chemists pinpoint role of cholesterol in cells

Scientists have long puzzled over cholesterol. It's biologically necessary; it's observably harmful - and nobody knows what it's doing where it's most abundant in cells: in the cell membrane.

Study provides insights into CPEB4 gene and fatty liver disease

This condition generally leads to chronic inflammation (non-alcoholic steatohepatitis), which can trigger fibrosis, cirrhosis and ultimately liver cancer. This study on the basic biology of the liver paves the way to examine therapeutic strategies to fight and prevent fatty liver disease.

People with metabolic syndrome may need more vitamin E, new research shows

New research has shown that people with metabolic syndrome need significantly more vitamin E - which could be a serious public health concern, in light of the millions of people who have this condition that's often related to obesity.

Could pathogen infection really lead to Alzheimer’s?

New concepts of infectious disease are evolving with the realization that pathogens are key players in the development of progressive chronic diseases that originally were not thought to be infectious. Infection is well-known to be associated with numerous neurological diseases for which...

Childhood obesity starts in the womb?

There is incontrovertible evidence that some harmful drugs and toxins can affect lifelong health. For example, if women take certain drugs in pregnancy, such as thalidomide, there are well documented effects on lifelong health. These have obvious and dramatic effects on the child...

TSRI biologists uncover new mechanism behind sense of touch

Biologists on the Florida campus of The Scripps Research Institute have discovered a new mechanism that likely underlies how we feel force or touch. Their study suggests that "rafts" of fatty lipids on the cell surface act as compartments to keep certain enzymes from mixing with their binding partners.

Researchers uncover reason for stent failure in diabetic patients with clogged arteries

People with any form of diabetes are at greater risk of developing cardiovascular conditions than people without the disease. Moreover, if they undergo an operation to open up a clogged artery by inserting a "stent" surgical tube, the artery is much more likely to clog up again.
