The Claim
Chronic stimulation of invariant natural killer T (iNKT) cells with α-GalCer in obese mice exacerbates insulin resistance and hepatic steatosis without affecting body weight.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In obese mice, prolonged activation of invariant natural killer T cells using α-GalCer increases insulin resistance and liver fat accumulation without changing body weight.
See the scientific wording
Chronic stimulation of invariant natural killer T (iNKT) cells with α-GalCer in obese mice exacerbates insulin resistance and hepatic steatosis without affecting body weight, demonstrating that iNKT cell activation can worsen metabolic outcomes independently of adiposity.
In obese mice, excess fat causes immune cells to present fat molecules to a specific type of immune cell called iNKT cells. These cells become overactive and release inflammatory signals that attract other immune cells to the liver and fat tissue. The inflammation blocks the body's ability to respond to insulin and forces the liver to store more fat, making insulin resistance and fatty liver worse—even if the animal doesn't gain more weight.
What the research says
1 studyIn obese mice, repeatedly activating a specific immune cell (iNKT) makes their blood sugar control and liver fat worse—even if they don’t get heavier—proving that immune activity alone can harm metabolism.
