Fibroblasts hold clues to fat, scars and inflammation

Scientists found certain fibroblasts can transform into myofibroblasts, leading to fibrosis, and lipofibroblasts, developing into fat cells that cause thyroid eye disease. This research may lead to new diagnostic tools and treatments for diseases like fibrosis and fatty tissue buildup.

Researchers found that 8 out of 20 commonly used NSAIDs can selectively lower Abeta42 levels in mice, with flurbiprofen showing the most promise. Additionally, studies revealed increased T cell reactivity to Abeta protein in older humans and patients with Alzheimer's disease, which could inform the design of future vaccines.

Obese mice provide clues to a natural system that puts brakes on obesity

Researchers have identified a gene called Foxa-2 that is switched on only in the fat cells of obese mice. This gene acts as a brake to slow down further fat production and storage. In pre-adipocytes, Foxa-2 activates genes important for insulin sensitivity, providing an ideal combination for treating obesity and type 2 diabetes.

Missing link detected in insulin mechanism

Researchers identify protein that bridges signaling and membrane movement, linking insulin's action to glucose uptake. This finding could provide clues for understanding type 2 diabetes, where muscle and fat tissues resist insulin.

Researchers found that RGS2-deficient mice developed strongly hypertensive conditions and persistent vessel constriction due to prolonged GPCR signaling. Genetic defects affecting RGS2 function may also contribute to hypertension in humans, according to findings published in the Journal of Clinical Investigation.

Cell division required, twice before fat cells mature

Cell division is necessary for fat cells to mature, according to a new study. The researchers found that primitive fat cells need to divide at least twice before they can store fat, and that interfering with this process could prevent the formation of new fat cells.

Anker Laptop Power Bank 25,000mAh (Triple 100W USB-C) keeps Macs, tablets, and meters powered during extended observing runs and remote surveys.

‘Futile’ cycle both fights diabetes and causes weight gain

TZDs trigger a 'futile' cycle where glycerol kinase stores fatty acids faster than fat cells release them, leading to increased insulin sensitivity. Researchers also found that TZDs alter chemical signals produced by fat cells, potentially benefiting future anti-diabetes drug development.

Cartilage made from stem cells tested in animals

Scientists have successfully implanted cartilage made from stem cells in mice, showing promise for repairing damaged tissues. The study uses fat cells to produce cartilage-like cells that can be used as implants to treat injuries and diseases.

Fat gene discovered

Researchers identify PPARgamma2 as critical player in fat cell differentiation process. The discovery provides a molecular target for rational drug design to combat obesity.

GQ GMC-500Plus Geiger Counter logs beta, gamma, and X-ray levels for environmental monitoring, training labs, and safety demonstrations.

Oxygen is toxic to stem cells

A study by Michigan Medicine researchers found that high oxygen levels can be toxic to stem cells, converting muscle cells into fat cells. This discovery has important clinical implications for the treatment of obesity and diabetes, as it may be related to aging and oxidative stress conditions.

Say what? Neurons and fat cells have a dialogue in the lab

Researchers found that signals from fat cells can directly influence neurons outside of the brain, affecting the storage and burning of fat. The study suggests that nerve cells outside of the brain secrete a messenger called neuropeptide Y to prevent fat deposits from being burned for energy.

Knockout of cav-1 protein causes loss of a cellular organelle

The study demonstrates a fundamental role of caveolin-1 and caveolae in organizing multiple signalling pathways in the cell. The absence of caveolae impaired nitric oxide and calcium signaling, leading to severe physical limitations in caveolin-1-disrupted mice.

'Fat-proof' mice yield new anti-obesity drug target

Researchers at Baylor College of Medicine have identified perilipin as a crucial protein that protects fat cells from breakdown. By eliminating this protein, mice lost weight despite consuming more food and gained increased muscle mass. The findings hold promise for developing new anti-perilipin drugs to combat obesity.

UGA Researchers First To Determine That Leptin Causes Death Of Fat Cells

Researchers at the University of Georgia have made a groundbreaking discovery that leptin causes the programmed death of fat cells. This finding could play a significant role in the development of new treatments for obesity, as rats injected with leptin stay thin even after treatment is stopped.
