Article Title: An Adipo-Pulmonary Axis Mediated by FABP4 Hormone Defines a Therapeutic Target Against Obesity-Induced Airway Disease
doi: 10.1101/2024.07.15.603433
Figure Lengend Snippet: A. Airway hyperresponsiveness in genetically obese (ob/ob) and lean wild type (WT) and FABP4 and FABP5 double knockout mice (FABP4-5 KO) on a Balb/C background. Measurements were performed using the FlexiVent Fx system with the forced oscillation technique, starting at baseline and then with increasing doses of methacholine (MeCh) up to 25 mg. B. Body weights from mice used in panel A (n=4-9 per group). C. Representative DEXA scanner body composition images from obese and lean WT mice, and quantification of thoracic fat percentage in WT and FABP4 KO lean and obese (ob/ob) mice (n=3-9 per group). D. Measurement of airway hyperresponsiveness in WT lean treated with PBS (WT PBS), WT obese treated with PBS (ob/ob), WT obese (ob/ob) treated with anti-FABP4 monoclonal antibody (mAb) (n=3-8 per group). E. Plasma and F. BALF FABP4 levels from mice in panel D, measured by ELISA. G. Measurement of airway hyperresponsiveness in WT lean, FABP4 KO lean, WT obese (ob/ob), FABP4 KO obese (ob/ob), and WT obese (ob/ob) mice treated with anti-FABP4 monoclonal antibody (mAb) (n=4-7 per group).
Article Snippet: Body composition was measured using a DEXA scanner (Lunar PIXImus2, GE Healthcare, Waukesha, WI) in anesthetized mice (100 mg/kg ketamine / 10 mg/kg xylazine, ip).
