Immune Signaling Proteins May Also Help in Regulating Obesity and Diabetes

Activating the sensor protein sets off a chain of events that instructs cells to use up their energy or fat stores to prevent excess fat accumulation.

A sensor protein could help fight against obesity and diabetes, revealed a new study. In the study, researchers showed a protein called NLRP1 is switched on when increased dietary energy (food) intake triggers the cell to become 'unstable'.

Activating the protein sets off a chain of events that instructs cells to use up their energy or fat stores to prevent excess fat accumulating.

Key Factor in Fat Storage and Energy Metabolism Discovered
Researchers have discovered a cell cycle transcriptional co-regulator – TRIP-Br2 that plays an important role in energy metabolism and fat storage.

Lead author Seth Masters from Melbourne's Walter and Eliza Hall Institute said NLRP1 was a biological sensor that could hold the key to developing new ways of treating obesity and type 2 diabetes. NLRP1 is a biological sensor that can respond to and prevent obesity and metabolic syndrome, which are causing a dramatically increasing burden of disease throughout the world.

The sensor is activated if it detects that the body's energy intake is too high. When the sensor is activated, it tells cells to burn fat stores to prevent excess build up of fat. We showed that without NLRP1, fat stores continue to build up, especially with a high-energy diet, leading to obesity, he added.

Masters said, “NLRP1 was more commonly known for its role in the immune system. However it is becoming increasingly clear that immune signaling proteins also have an important role in regulating metabolism." However the investigators cautioned that the treatment would have to be tightly controlled to avoid potential side-effects.

Health Problems Triggered Off by Cell's Fat Storage Capacity
Acutely obese people and animals have fat cells that have a limit of storing fat which when exceeded would trigger off other health problems.

Masters said, "Our research showed that activation of NLRP1 could be exacerbated by some diets, and identified that there is a fine balance between increasing the cell's fat burning abilities and causing harm." The study is published in the journal Cell Metabolism.

Worried About Fat Storing On Your Hips? Instead Thank As It Lessens Diabetes Risk!
Women who carry fat in their hips - those with a 'pear-shaped' body type - are significantly less likely to develop diabetes than those with smaller hips.

Researchers Discover Mechanism Behind Fat Cells Losing Storage Ability
A mechanism that causes fat cells to lose their ability to efficiently store and use energy has been discovered by Yale University researchers.
