The obesity marker FABP4 induces vascular inflammatory atherosclerosis (García-Vega et al., 2024) and prior research has demonstrated that GLP-1 can affect the course of this disease (Park et al., 2024; Rakipovski et al., 2018; Saraiva and Franco, 2021). Here, FABP4 is linked to obesity due to melanocortin 4 receptor deficiency.
