Background: It showed that the infiltration of macrophages into adipose tissue is the origin of inflammation. Despite the positive effect of training and octopamine on the inflammatory process and adipose tissue permeability to macrophages, the simultaneous effect of aerobic training (AT) and octopamine (O), as a lipolytic agent on macrophage permeability in a high-fat diet situation, is unclear. Objectives: This study aimed to investigate the effect of AT and O supplementation on CD86 and CD206 concentration in white adipose tissue of rats poisoned with deep-fried oil (DFO). Methods: A total of 30 male Wistar rats were divided into groups, including healthy control, DFO control, AT + DFO, O + DFO, and AT + O + DFO. During the four weeks the O groups received 81 µmol/kg octopamine for five days/week intraperitoneally, and AT groups performed training with moderate intensity (26 m/min). Forty-eight hours after the last intervention, the rats were anesthetized and subcutaneous adipose tissue was removed for CD86 and CD206 assays. Results: DFO significantly increased CD86 and reduced CD206; AT was able to reduce the CD86 increase, however, it had no effect on CD206; O significantly reduced CD86 and increased CD206; in addition, interaction of AT and O on CD86 was significant. Conclusions: Both AT and O can reduce the negative effect of deep-fried oil on macrophage permeability in adipose tissue.
