With age, people become more susceptible to cold as inflammation and metabolic problems which can lead to a host of chronic diseases. Researchers at Yale and the University of California-San Francisco have found one culprit in this process — the same immune cells within fat that are designed to protect us from cold temperatures.

Abstract Excessive visceral fat accumulation is a primary risk factor for metabolically unhealthy obesity and related diseases. The visceral fat is highly susceptible to the availability of external nutrients. Moreover, adipose OGT overexpression inhibits lipolysis and promotes diet-induced obesity. These findings establish an essential role for OGT in adipose tissue homeostasis and indicate a unique potential for targeting O-GlcNAc signaling in the treatment of obesity.

In obese individuals, cellular "doormen" open the gates far too wide in certain key fat cells, known as visceral fat cells, letting in too many carbohydrates without first burning off lipids. This leads to a ballooning of the size of visceral fat cells in the belly.

A study by researchers at Yale has uncovered why belly fat surrounding organs increases as people age, a finding that could offer new treatment possibilities for improving metabolic health, thereby reducing the likelihood for diseases like diabetes and atherosclerosis that stem from inflammation.

The researchers reaffirmed that inflammation occurs in the hypothalamus as early as three days after consumption of a high-fat diet, even before the body begins to display signs of obesity.

In the search for obesity treatments, scientists recently zeroed in on a gene known as Nucleobindin-2 (Nucb2), which was believed to play a role in satiety. However, in a new study published in Cell Reports, Yale researchers uncovered an unexpected function for the gene in reducing inflammation.
