Aflibercept  (Synonyms: VEGF Trap; VEGF-TRAPR1R2; VEGF-trapR1)

Aflibercept (VEGF Trap) is a soluble decoy VEGFR constructed by fusing the Ig domains of VEGFR1 and VEGFR2 with the Fc region of human IgG1. Aflibercept inhibits VEGF signaling by reducing VEGF-regulated processes. Aflibercept can be used for thr research of age-related macular degeneration (AMD) and cardiovascular disease^[1][2][3].

Aflibercept (500 μg/mL; 24 h and 7 d) shows no toxicity on RPE cells, neither in MTT-assay nor in trypan blue exclusion assay^[1].
Aflibercept (500 μg/mL; 24 h) shows a statistically significant effect on wound healing compared with control in the confluent RPE cell layer with three wounds^[1].
Aflibercept (500 μg/mL; 7 d) displays a significantly diminished phagocytosis of opsonised latex beads compared to untreated control^[1].
Aflibercept (1 and 10 μg/mL; 10 h) inhibits VEGF signaling by reducing VEGF-regulated processes, such as permeability and angiogenesis^[2].

Aflibercept (10 mg/kg; 3 h post-middle cerebral artery occlusion (MCAO)) reduces stroke-induced VEGF-A and VEGFR2 expression, and brain edema, and BBB disruption and improves poststroke survival in obese mice^[2].
Aflibercept (18.2 mg/kg and 36.4 mg/kg; i.v. once) affects BP, ROS and eNOS production in mice^[3].
