eLife Assessment
The study presents important findings on inositol-requiring enzyme (IRE1α) inhibition on diet-induced obesity (overnutrition) and insulin resistance where IRE1α inhibition enhances thermogenesis and reduces the metabolically active and M1-like macrophages in adipose tissue. The evidence supporting the conclusions is convincing. The work will be of interest to cell biologists and biochemists working in metabolism, insulin resistance and inflammation with a broad eLife readership.
