IL-6 induces IL4ralpha expression in macrophages. This mechanism is necessary to promote macrophage polarization towards an M2-phenotype and is crucial to limit the inflammatory response both upon obesity and LPS-endotoxemia.
Signaling by IL-6 promotes alternative activation of macrophages to limit endotoxemia and obesity-associated resistance to insulin.

In this study we implemented IGF1R knockout mice in the olfactory sensory neurons, by olfactory marker protetin (OMP) Cre specific recombination, and investigated metabolic parameters, smell perception and transcriptome sequencing. We could demonstrate that IGF1R knockout in the olfactory sensory neurons results in enhanced smell perception, insulin resistance under normal chow diet conditions and increased adiposity in mice fed control diet. Transcriptome analysis of the olfactory epithelium revealed differential expression of markers for mature and immature olfactory sensory neurons, being down-regulated and up- regulated respectively, pointing to differentiation-dependent changes that result in increased olfactory perception. Collectively, this study provides evidence that enhanced smell perception can result in insulin resistance and increased adiposity. Overall design: mRNA profiles of olfactory sensory neurons (OSN) extracted from homozygous tissue-specific IGF1R knockout (OMPIGF1R) and respective cotnrol mice (OMPflfl) were generated by deep sequencing, in four replicates using Illumina sequencing

View SamplesHuman rhinoviruses (HRV) are among the most common causes of respiratory infections in humans but can be frequently detected also in asymptomatic subjects. We evaluated the value of gene expression profiles to differentiate asymptomatic detection from symptomatic HRV infection in children.
