A Study to Analyze the Effect of Obesity on Eosinophil (disease fighting white blood cell) Recruitment in Human Adipose Tissue


About this study

To determine whether EOS recruitment in AT is impaired during obesity. Therefore, we hypothesize that chronic, low-grade inflammation of AT initiates epigenetic modifications in EOS and/or in AT, thereby impairing the recruitment of eosinophils.
