Abstract

Introduction: TNF-α plays a key role in initiating pathologic angiogenesis, however, literature on the effects of infliximab on angiogenesis is limited. Objective: The study aimed to investigate the effects of infliximab on angiogenesis in an in vivo chick chorioallantoic membrane (CAM) model. Methods: The study was approved by the local ethics committee on animal experimentation. Thirty fertilized specific pathogen-free eggs were incubated and kept under appropriate temperature and humidity control. On the third day of the incubation, infliximab (1 µmol) dissolved in phosphate-buffered saline in the first group, phosphate-buffered saline (negative control) (0.1 ml) in the second group, anti-VEGF (positive control) (1 µmol) in the third group were administered by injection. On the eighth day of incubation, the vascular structures of the CAMs were macroscopically examined, and standard digital photographs were taken. The digital images were analyzed, and data including mean vessel density, thickness, and number were compared between groups. P < 0.05 was considered statistically significant. Results: Angiogenesis was significantly reduced in the anti-VEGF and infliximab groups compared to the saline-only group. Vessel thickness, vessel number, and vessel density were significantly less in the infliximab and anti-VEGF groups compared to the saline-only group (p=0.034, 0.029, 0.024, respectively). Conclusions: Infliximab showed promising antiangiogenic effects in the chick CAM model. Thus, infliximab could be a treatment agent in pathological processes in which angiogenesis is responsible. The antiangiogenic effect of infliximab could be due to the inhibition of various angiogenesis-related cytokines and adhesion molecules. Further studies are needed to clarify the exact mechanisms.
